Natural phenomena

natural phenomena are all the changes that occur in nature

Thermometer is a temperature measuring device.

Mark (color the plate) objects of nature in green, natural phenomena in yellow. Make pairs "object - phenomenon".

Pairs "object - phenomenon": the sun is a solar eclipse, a grain of wheat is the germination of grain, a snowflake is snowfall, ice is the melting of ice, a tiger is the growl of a tiger, a chicken egg is the appearance of a chicken from an egg.

Complete the table (write at least three examples in each column).

Ant Question, as in the last academic year, drew pictures. He tried very hard, but Seryozha and Nadia's dad said that Ant had mixed up something again. Find mistakes. Count and write down how many mistakes are in each picture. Prove the correctness of your decision.

Mistakes
Picture Summer:
It is warm in summer, there cannot be ice on the river and snow on the shore, for the same reason it cannot snow. Migratory birds do not fly away in summer. The leaves on the trees are not turning yellow yet. Fly agaric does not grow on the river bank.
In total, six errors were counted in this figure. The number "6" must be written in a circle.
Picture Spring:
If the birds have already had chicks, there are already lush foliage on the birch, lilies of the valley and chamomile are blooming, then this is late spring. From this it follows that autumn yellow leaves are mistakenly drawn in the picture, there should not be snow on the ground, as well as on the Christmas tree, at that time it had already melted all over. The picture shows that the day is sunny, dry, so there should not be a rainbow that appears after the rain.
In total, four errors were counted in this figure. The number "4" must be written in a circle.

Sign the thermometer parts

Mark with arrows what happens to the liquid column in the thermometer tube.

Do the exercises.
1) Write in numbers:
ten degrees +10°
ten degrees of frost -10°
zero degrees 0°
six degrees above zero +6°
six degrees below zero -6°

2) Write in words:
+5° five degrees Celsius
-7° seven degrees below zero

Have a nice day. In today's article, I want to tell you about the most interesting natural phenomena that exist on our vast earth, some of which are very dangerous, but so beautiful and wonderfully interesting that many people watch them on purpose, because they cannot take their eyes off them. .

Surprisingly complex and interesting is our world of wildlife and, apparently, therefore, many natural phenomena do not cease to amaze and amaze people with their unimaginable diversity. They make you think and admire your unnatural beauty.

It is known from the school course that various natural changes occurring in the environment are usually called phenomena that can be classified according to several criteria of origin and impact, duration of distribution and regularity of action. All of them can be divided into three main classes:

1. physical - where substances are not subject to change,
2. chemical - where one substance is converted into another,
3. biological - where certain changes occur in living organisms.

Physical phenomena include such types of phenomena as:

• electrical - thunderstorms and lightning, lightning and radiance,
• mechanical - movement and movement, running and flying, rolling, swinging and swimming,
• optical - rainbows and mirages, prize and crown, halo and pillars,
• magnetic - storms and anomalies, with such meteorological parameters: humidity and temperature of the environment (air, water, soil),
• light - sun and moon, sunrise and sunset, multicolor and luminescence,
• sound - thunder and rustle, noise and knock, tramp and creak, voices and explosions,
• thermal - heating and cooling, solidification and melting, boiling, evaporation and condensation.

Chemical phenomena include such types of phenomena as:

1. combustion of any substances and smoke in the air
2. decay (decomposition and destruction) of animal and plant tissue,
3. explosion of gases and dust, liquids and vapours.

Biological phenomena include such types of phenomena as:

• flowering plant,
• autumn leaf fall,
• Animal Moult,
• arrival of migratory birds,
• hibernation of animals.

In addition to the main types of natural phenomena, one can also recall additional phenomena, such as:

1. whirlwinds and tornadoes,
2. squall and storm
3. wind and darkness

According to the seasons - seasonal natural phenomena:

• spring - flood and ice drift, melting snow with the appearance of thawed patches and the formation of icicles, awakening and flowering,
• summer - heat and rain, dew and a colorful rainbow, a thunderstorm with thunder and lightning,
• autumn - fogs and leaf fall, showers and winds, hoarfrost and frosts,
• winter - blizzards and snowfalls, frost and black ice, drizzle and blizzards, crust and freezing.

So we learned what natural phenomena are, what they are and what they are connected with.

Phenomena taking place in the sky

Since ancient times, man has been interested in the environment with its huge variety of incomprehensible and sometimes surprising manifestations of nature, which is probably why he was interested in observing them.

After all, a person is naturally curious, and therefore interested in everything that surrounds him. Interesting phenomena of nature were no exception for him.

Let's move on to the most interesting celestial phenomena.

It is very interesting for many people to observe the movement of various clouds in the sky, and yet their numerous diversity and speed of movement is sometimes mesmerizing.
Maybe you have thought about why it is interesting for a person to observe natural phenomena occurring high in the sky? After all, this process of observation is as simple as it is interesting.

A very rare sight in terms of beauty - mother-of-pearl clouds can be observed high in the stratosphere, where there is not enough moisture for their formation. However, during periods of cold winters, the amount of moisture increases, and already these clouds form in a lower layer at about 20 kilometers.

Vymeobraznye or tubular clouds of a dark gray hue are formed due to the dense accumulation of clots of air and in appearance look like picturesque groups of balls. As a rule, such terry clouds appear in the tropics, where numerous tropical cyclones are especially active.
Have you seen clouds in the sky that look like horse heads? This unusual configuration of clouds is caused by the formation of wind breakers, which move through the sky faster than water. You can usually see them in Alabama.

And how beautiful are the feathers of an angel in the sky, appearing after the flight of an airplane, creating an artificial gap in the sky. It occurs when a strong current of air passes through cirrus or cumulus clouds.

No less interesting are lenticular clouds, similar to unidentified flying objects from other planets, the formation of which is impossible without humid mountain air.

Each of us, but at least once in his life observed such a beautiful phenomenon as a colored rainbow, and there are many such different rainbows in nature, and one of them is a white foggy rainbow, similar to a whitish semicircle of water drops in fog. In such small water droplets, the usual scattering of the spectrum of sunlight does not occur, and therefore the rainbow itself turns out to be whitish.

But the fiery rainbow appears high in the sky, where you can see quite a lot of ice crystals, from which the sun's rays are refracted. At the same time, the celestial horizon is painted in different chaotic colors, and the ice crystals themselves are located parallel to the surface of the earth.

There is also a wonderful lunar rainbow, which can be observed in the dark sky of a falling waterfall in the form of a powerful scattering rainbow light rising above the water in a multi-colored fog.

Phenomena from water ice and snow

Once at sea, I had to observe a water tornado that literally grew before my eyes above the surface of the water surface. Its vortex funnel rotating inside sucked in a huge mass of water from the surface of the sea with great speed and raised it to a sufficiently high height.
The entire raised mass of sea water immediately formed a huge dark cloud, which quickly moved towards the coastline, but the warm coastal air did not allow it to approach and fall on the resting people, but carried it away to the other side, where it immediately poured heavy rain.

Apparently because I live in the south of our country, I really like to watch in the winter how high piles of snow form on the streets of our northern cities.

If they are not removed in a timely manner, then over time they turn into huge snow monsters, which become larger and larger every day, and resemble scary frightening monsters in appearance.

The picture is certainly creepy, but all hope for warm sunny days, when all this ice block begins to quickly melt and turn into melt water.
No less interesting is the ice analogue of a mountain stalactite in the form of an ice icicle located under water. She received a frightening name - the finger of death, as she destroys everything that comes across to him in the course of his growth.

And the process of formation of this interesting natural phenomenon is quite understandable - it is formed at the point of collision of two streams of icy water - slightly salty and oceanic enough salty.

On a thin layer of sea ice, a kind of flower field, you can sometimes see unusual snow flowers in the form of beautiful ice crystals, which are formed only in a cold atmosphere when moist cold air interacts with warm air.

In those distant times, when the sea level was lower than the current one, and various natural phenomena affected its bottom, thanks to erosion processes, huge funnel holes more than 100 meters deep were formed, the growth of which stopped only after they began to fill with sea blue water.

And how incredibly beautiful the multi-colored spotted lake looks with bizarrely round mineral formations, where each has its own specific color, depending both on the amount and on the composition of the mineral itself.

In areas with terrestrial activity, unusual ghostly steam towers can be observed that rise high above the ground from hot swamp gullies. This is an interesting natural spectacle, and you can see it in the country of volcanoes in Iceland.

And how interesting are the ice caves formed by frozen water on the edges of glaciers, where a thick layer of ice has a unique blue color and contains almost no air.
Another interesting miracle of nature can be considered the longest giant tidal wave in height of 5 meters - pororoka. This endless wave with a length of 800 kilometers during the winter-spring period of the tides moves from the Atlantic to the shores of the Amazon.

When two strong sea currents meet, circular giant whirlpools appear. This unusually beautiful movement of water can be observed on a fairly large surface, because its dimensions can reach several kilometers.

And, perhaps, the most beautiful phenomenon of nature can be considered unusually soft ice hair that appears due to plants, or rather the bacteria that lives in it.
Living inside the plant, this unusual bacterium affects the freezing temperature and as soon as the liquid of the plant disappears, the cold air forms such an unusual drizzle.

Phenomena formed by living organisms

Numerous colonies of tiny night-light organisms, which have the amazing ability to glow in the dark, can be considered a marine miracle of wildlife, formed by living organisms.

They often gather near the water surface and emit their amazing light, which can be seen even from a great height.

It is literally before our eyes, turns into a blooming multi-colored carpet in the open air.

In the sandy soil of the desert, one can observe the so-called witch circles of large diameter. The culprits of such peculiar spots are termite insects that live and eat plant roots in this place.

Isn't it interesting two-meter strange underwater circles that appear on the seabed, each of which is distinguished by its original shape.

And the culprit for the emergence of these unusual works of art is the male of a small fish, the puffer fish, which, by flapping its movable fins, creates them, in this way attracting a female to itself.
Luminescent waves are of great interest to many people, their luster glowing along the coast in the dark causes plant phytoplankton in the form of unicellular algae.

Of particular interest to people are iridescent eucalyptus trees, the diversity of which is due to the fact that the plant itself is unevenly freed from the bark in time and therefore its trunk acquires a different color.

An interesting miracle in the world of insects can be called a millionth invasion of spiders, which, fleeing from a water flood, climbed high trees, where they built nests for themselves.

Looking at them, during the rainy season there is a large migration of crabs. These red inhabitants of the forest are attracted to the coast by the eternal instinct of reproduction.

For the same reason, numerous butterfly migrations occur every year. Their long journey is sometimes carried out over distances of up to 5 thousand kilometers.

Of course, these are not all the interesting natural phenomena that exist in the world around us, but it will not be so easy to list them all in this article, so I will limit myself to only these.

And that's all for today. I hope you enjoyed my article about interesting natural phenomena occurring on our earth. Maybe you have seen some of them, write about it in your comment, I would be interested to know about it. And now let me say goodbye to you and see you again.

I suggest you subscribe to blog updates. If you really liked the article, you can rate it on a 10-point system, marking it with a certain number of stars.

Subject: General concepts of dangerous and emergency situations of a natural nature.

Lesson topic: Natural phenomena and their classification.

The purpose of the lesson: To acquaint students with natural phenomena and their diversity.

Lesson objectives:

I. Educational tasks:

• Recall and consolidate knowledge about the shells of the Earth.
• To form students' knowledge that the formation of any natural phenomenon is associated with the processes occurring in the Earth's shells.
• To give a general idea to students about the types of natural phenomena at the place of their occurrence.

II. development tasks.

• To develop in students the ability and ability to foresee the natural phenomena of their area, which can lead to serious consequences, as well as ways to protect against them.

III. educational tasks.

• To instill in students the belief that any natural phenomenon of destructive power brings huge damage to the state of various types, primarily material and loss of life. Therefore, the state needs to send funds to scientific institutions so that they deal with this problem and be able to predict them in the future.

During the classes

Teacher: Today, children, we will talk about natural phenomena and their diversity. Of course, you know some, some you learned from the course of natural history and geography, and if someone is interested in the media, then from there. If you turn on the TV, radio or use the Internet, then we can say with confidence that natural phenomena of destructive power are occurring more and more often, and their strength is becoming greater. Therefore, we need to know what natural phenomena occur, where they occur most often and how to protect ourselves from them.

Teacher: And so let's remember from the course of geography what shells of the Earth exist.

In total, 4 shells of the Earth are distinguished:

1. Lithosphere - it includes the earth's crust and the upper part of the mantle.
2. The hydrosphere is a water shell, it includes all water in different states.
3. The atmosphere is a gas shell, the lightest and most mobile.
4. The biosphere is the sphere of life, it is the area of ​​existence of all living organisms.

Teacher: In all these shells, certain processes take place, as a result of which natural phenomena arise. Therefore, various natural phenomena can be divided according to the place of their occurrence:

Teacher: From this diagram, we see how many natural phenomena exist. Now let's look at each of them and find out what they are. (Children should take an active part in this part.)

Geological.

1. An earthquake is a natural phenomenon associated with geological processes occurring in the Earth's lithosphere, it manifests itself in the form of tremors and vibrations of the earth's surface resulting from sudden displacements and ruptures in the earth's crust or in the upper part of the mantle.

Picture 1.

2. A volcano is a conical mountain, from which an incandescent substance, magma, erupts from time to time.

A volcanic eruption is the release of molten matter from the earth's crust and mantle, which is called magma, to the surface of the planet.

Figure 2.

3. A landslide is a downward displacement of soil masses under the action of gravity, which occurs on slopes when the stability of the soil or rocks is disturbed.

The formation of landslides depends on various factors such as:

• what rocks make up this slope;
• slope steepness;
• ground water, etc.

Landslides can occur both naturally (eg earthquake, heavy rainfall) and man-made (eg human activities: deforestation, excavation).

Figure 3

4. A collapse is a detachment and fall of large masses of rocks, their overturning, crushing and rolling on steep and steep slopes.

Causes of landslides in the mountains can be:

• the rocks that make up the mountains are layered or broken by cracks;
• water activity;
• geological processes (earthquake), etc.

Causes of collapses on the coast of seas and rivers are the washing and dissolution of the underlying rocks.

Figure 4

5. An avalanche is a collapse of a mass of snow on mountain slopes, the slope angle must be at least 15 °.

The causes of an avalanche are:

• earthquake;
• intensive snow melting;
• prolonged snowfall;
• human activity.

Figure 5

Meteorological.

1. A hurricane is a wind whose speed exceeds 30 m/s, resulting in huge destruction.

Figure 6

2. A storm is a wind, but with a lower speed than in a hurricane and is no more than 20 m/s.

Figure 7

3. A tornado is an atmospheric vortex that forms in a thundercloud and descends, has a funnel or sleeve head start.

A tornado consists of a core and a wall. Around the core there is an upward movement of air, the speed of which can reach 200 m / s.

Figure 8

Hydrological.

1. Flooding is a significant flooding of the area as a result of a rise in the water level in a lake, river, etc.

Reasons for the flood:

• intensive snowmelt in spring;
• heavy rainfall;
• blockage of the river bed with rocks during an earthquake, collapse, etc., as well as ice during traffic jams;
• wind activity (water surge from the sea, bay at the mouth of the river).

Types of floods:

Figure 9

2. Mudflow is a stormy stream in the mountains of a temporary nature, consisting of water and a large number of rock fragments.

The formation of mudflows is associated with abundant precipitation in the form of rain or intense snowmelt. As a result, loose rocks are washed away and move along the river bed at high speed, which picks up everything in its path: boulders, trees, etc.

Figure 10.

3. Tsunami is a type of sea waves resulting from the vertical shift of large areas of the seabed.

A tsunami occurs as a result of:

• earthquakes;
• underwater volcano eruptions;
• landslides, etc.

Figure 11.

Biological.

1. A forest fire is an uncontrolled burning of vegetation, spontaneously spreading through a forest area.

Forest fire can be: grassroots and riding.

An underground fire is the burning of peat in marshy and swampy soils.

Figure 12.

2. An epidemic is the spread of an infectious disease among a large number of the population and significantly exceeds the incidence rate usually recorded in the area.

Figure 13.

3. An epizootic is a widespread infectious disease among animals (for example: foot-and-mouth disease, swine fever, bovine brucellosis).

Figure 14.

4. Epiphytotics is a mass spread of an infectious disease among plants (for example: late blight, wheat rust).

Figure 15.

Teacher: As you can see, in the world there are a huge number of phenomena that surround us. So let's remember them and be extremely careful at the time of their occurrence.

Some of you may say: “Why do we need to know all of them if they are not typical for our region?”. From one point of view you are right, but from the other you are wrong. Each of you tomorrow, the day after tomorrow or in the future will surely go on a trip to other parts of the Motherland and the country. And there, as you know, there can be completely different phenomena that are not typical for our area. And then your knowledge will help you survive in a critical situation and avoid negative consequences. As the saying goes: "God saves the safe."

Changes are constantly taking place in nature and weather, sometimes it snows, sometimes it rains, sometimes the sun bakes, sometimes clouds appear. All these are called natural phenomena or phenomena of nature. Natural phenomena are changes that occur in nature regardless of the will of man. Many natural phenomena are associated with the change of seasons (seasons), so they are called seasonal. For each season, and we have 4 of them - this is spring, summer, autumn, winter, its natural and weather phenomena are characteristic. Nature is usually divided into living (these are animals and plants) and non-living. Therefore, phenomena are also divided into phenomena of living nature and phenomena of inanimate nature. Of course, these phenomena intersect, but some of them are especially characteristic of a particular season.

In the spring, after a long winter, the sun warms up more and more, ice begins to drift on the river, thawed patches appear on the ground, buds swell, and the first green grass grows. The day is getting longer and the night is getting shorter. It is getting warmer. Migratory birds begin their journey to the regions where they will raise their chicks.

What natural phenomena occur in spring?

Snowmelt. As more heat comes from the Sun, the snow begins to melt. The air around is filled with the murmur of streams, which can provoke the onset of floods - a clear sign of spring.

thawed patches. They appear wherever the snow cover was thinner and where more sun fell on it. It is the appearance of thawed patches that indicates that winter has given up its rights, and spring has begun. The first greenery quickly breaks through the thawed patches; on them you can find the first spring flowers - snowdrops. Snow will lie in crevices and depressions for a long time, but on the hills and in the fields it melts quickly, exposing the land islands to the warm sun.

Frost. It was warm and suddenly it froze - frost appeared on the branches and wires. These are frozen crystals of moisture.

Ice drift. In spring it becomes warmer, the ice crust on rivers and lakes begins to crack, and gradually the ice melts. Moreover, there is more water in the reservoirs, it carries the ice floes downstream - this is an ice drift.

High water. Streams of melted snow flow from everywhere to the rivers, they fill the reservoirs, the water overflows the banks.

Thermal winds. The sun gradually warms the earth, and at night it begins to give off this heat, winds are formed. While they are still weak and unstable, but the warmer it gets around, the more the air masses move. Such winds are called thermal, they are typical for the spring season.

Rain. The first spring rain is cold, but not as cold as snow :)

Thunderstorm. At the end of May, the first thunderstorm can thunder. Not as strong yet, but bright. Thunderstorms are discharges of electricity in the atmosphere. Thunderstorms often occur when warm air is displaced and lifted by cold fronts.

Grad. This is a drop from a cloud of ice balls. Hail can be anything from a tiny pea to a hen's egg, and then it can even break through the windshield of a car!

These are all examples of inanimate phenomena.

Flowering is a spring phenomenon of wildlife. The first buds on the trees appear in late April - early May. The grass has already broken through its green stems, and the trees are getting ready to put on green clothes. The leaves will bloom quickly and suddenly, and the first flowers are about to bloom, exposing their centers to awakened insects. Summer will come soon.

In summer, the grass turns green, flowers bloom, leaves turn green on the trees, you can swim in the river. The sun warms well, it can be very hot. Summer is the longest day and the shortest night of the year. Berries and fruits ripen, the harvest ripens.

In summer, there are natural phenomena, such as:

Rain. In the air, water vapor is supercooled, forming clouds consisting of millions of small ice crystals. The low temperature in the air, below zero degrees, leads to the growth of crystals and to the weight of frozen drops, which melt in the lower part of the cloud and fall in the form of raindrops to the surface of the earth. In summer, the rain is usually warm, it helps to water the forests and fields. Thunderstorms often accompany summer rain. If it rains and the sun shines at the same time, they say that it is "Mushroom rain". Such rain happens when the cloud is small and does not cover the sun.

Heat. In summer, the rays of the Sun fall on the Earth more vertically and heat its surface more intensively. And at night, the earth's surface gives off heat to the atmosphere. Therefore, in summer it is hot during the day and sometimes even at night.

Rainbow. Occurs in an atmosphere with high humidity, often after rain or thunderstorms. A rainbow is an optical phenomenon of nature, for the observer it appears as a multi-colored arc. When the sun's rays are refracted in water droplets, an optical distortion occurs, which consists in the deviation of different colors, the white color is divided into a spectrum of colors in the form of a multi-colored rainbow.

Flowering begins in spring and continues all summer.

In autumn, you no longer run outside in a T-shirt and shorts. It gets colder, the leaves turn yellow, fall off, migratory birds fly away, insects disappear from sight.

Autumn is characterized by such natural phenomena:

Leaf fall. As plants and trees go through their year-round cycle, they shed their leaves in the fall, exposing their bark and branches, preparing for hibernation. Why does a tree get rid of leaves? So that the fallen snow does not break the branches. Even before the leaf fall, the leaves of the trees dry, turn yellow or redden and, gradually, the wind throws the leaves to the ground, forming a leaf fall. This is an autumn phenomenon of wildlife.

fogs. The earth and water are still heated during the day, but in the evening it is already getting colder, fog appears. At high humidity, for example, after rain or in a damp, cool season, the cooled air turns into small droplets of water hovering above the ground - this is fog.

Dew. These are droplets of water from the air that have fallen in the morning on the grass and leaves. During the night, the air cools down, the water vapor that is in the air comes into contact with the surface of the earth, grass, tree leaves and settles in the form of water droplets. On cold nights, the dew drops freeze, causing it to turn to frost.

Shower. It's heavy, torrential rain.

Wind. This is the movement of air currents. In autumn and winter the wind is especially cold.

As in spring, there is frost in autumn. This means that there is a slight frost on the street - frost.

Fog, dew, downpour, wind, hoarfrost, frost - autumn phenomena of inanimate nature.

In winter it snows and it gets cold. Rivers and lakes are frozen over. In winter, the longest nights and shortest days, it gets dark early. The sun hardly heats up.

Thus, the phenomena of inanimate nature characteristic of winter are:

Snowfall is the fall of snow.

Blizzard. It's snowfall with wind. Being outdoors in a snowstorm is dangerous, it increases the risk of hypothermia. A strong blizzard can even knock you down.

Freezing is the formation of a crust of ice on the surface of the water. The ice will last all winter until spring, until the snow melts and the spring ice drifts.

Another natural phenomenon - clouds - happens at any time of the year. Clouds are water droplets that have collected in the atmosphere. Water, evaporating on the ground, turns into steam, then, together with warm air currents, rises above the ground. So water is transported over long distances, the water cycle is ensured in nature.

Unusual natural phenomena

There are also very rare, unusual natural phenomena, such as the northern lights, ball lightning, tornadoes and even fish rain. One way or another, such examples of the manifestation of inanimate natural forces cause both surprise and, at times, alarm, because many of them can harm a person.

Now you know a lot about natural phenomena and you can accurately find those characteristic of a particular season :)

The materials have been prepared for a lesson on the subject of the World around us in grade 2, the Perspective and School of Russia (Pleshakov) programs, but will be useful to any primary school teacher, and parents of preschoolers and younger students in home schooling.

Despite the fact that people have long given a description and found a rational explanation for why certain natural processes and phenomena occur, the most unusual and rare of them still amaze, delight and amaze, in particular, fire-breathing mountains spewing lava that sweeps away everything on his way; breathtaking whirlwinds rushing at great speed and raising stones, logs, cars and even entire houses into the sky; incredible fountains of boiling water rising tens of meters from the depths of our planet.

What is a natural phenomenon

Natural phenomena are ordinary, and in some cases supernatural meteorological and climatic processes, as a result of which nature naturally changes. At the same time, they can be quite harmless and do not cause absolutely no surprise in people and be taken for granted, for example, when it snows or rains, or they can represent real natural disasters, sowing death and destruction around them.

Classification of natural phenomena

Scientists have begun to study the extraordinary manifestations of the natural world since ancient times, and recently, when science began to move forward by leaps and bounds, its secrets gradually began to be revealed more and more quickly, for example, already in the 17th century. Gilbert proved that our planet is a huge magnet with poles, and a century later Franklin discovered atmospheric electricity.

Since there are a great many natural phenomena on our planet, very little is known about them so far. Therefore, there is nothing surprising in the fact that scientists have made their description, systematized and classified. Thanks to this, it became possible not only to study the types of natural processes by category, but also to predict and even prevent the possible occurrence of dangerous natural phenomena, but the amazing manifestations of the natural world are so unpredictable that it is not always possible to do this even with the latest equipment.

The following classification is rather conditional, since the same phenomenon of the natural world quite often corresponds to several points at once. Thus, natural phenomena are distinguished:

By the nature of the impact- some types of natural processes or phenomena can have several characteristics at once, for example, a severe flood can be destructive in a city, paralyze traffic on roads and deplete the soil, making it unsuitable for a good harvest.

• Natural disasters of a destructive nature - hurricanes, tornadoes, earthquakes, even an invasion of pests (locusts);
• Paralyzing natural phenomena completely or for a long time stop traffic (snowfall, ice, fog);
• Phenomena with a debilitating effect, due to which productivity and soil fertility decrease, groundwater is depleted and the supply of other natural resources decreases;

Origin:

• Natural disasters that cause man-made accidents - lightning, ice, biochemical corrosion.
• Climatic - these species are the most common. Examples are a typhoon, a snowstorm, or rain;
• Geological and geomorphological - these are natural natural phenomena such as tsunamis, earthquakes, volcanic eruption;
• Biogeochemical - hazardous natural phenomena of this type are mainly emissions of harmful gases from lakes, swamps and other water bodies;
• Biological - their appearance is often caused by objects of wildlife: increased reproduction of agricultural pests, as well as blood-sucking insects, predatory and poisonous animals, epidemics, diseases of plants and livestock.
• Space - first of all, the excessive activity of the sun also affects our world and space weather is dangerous for our world. For example, flares and emissions of charged solar particles and their interaction with the atmosphere and magnetic fields of our planet often lead to emergency situations.

By duration:

• Instant - do not last long (within a few seconds or minutes) and are the most dangerous (for example, earthquakes);
• Short-term natural phenomena last from several hours to several days (squalls, floods, rain, heat and, interestingly, the full moon);
• Long-term (the period of their action is longer and often amounts to months, and in some cases years) - this type of phenomena includes natural processes lasting months and even years (for example, volcanic eruptions, the emergence of ozone holes, the drying up of water bodies);
• Age-old - last for more than a dozen years and can stretch for centuries (global warming).

By regularity of action:

• Diurnal - for example, sunset and sunrise;
• Seasonal - leaves fall in autumn, buds appear on trees and bushes in spring.

Distribution scale:

• Global
• Local
• Regional

The influence of nature on man

Scientists have long noticed that nature actively influences not only the life of our planet, but also the health and well-being of a person and even his life expectancy. An important role in this case is given to such factors as the quality of water, land, air purity, climatic conditions.

For example, if people live in a territory unfavorable for living (too cold temperatures in winter and high in summer, high humidity, extremely strong winds), then it will be difficult for the human body to withstand, it will quickly fail and become unusable.

A person absolutely does not notice the influence of such natural conditions on his body, but pays attention only to the most unusual (for example, rainbows, northern lights, light pillars), mysterious (the mystery of the Bermuda Triangle has been haunting people for a long time) or dangerous natural phenomena that can lead to serious man-made accidents or human death.

site about the most interesting phenomena

On our site you will find information about the most unusual and amazing natural phenomena and their impact on the world around us. For example, you will be interested to know that the rainbow is not only solar, but also lunar, foggy, fiery or inverted. Also learn why people see mirages, auroras or halos.

Here you will read about dangerous natural phenomena that amaze with their beauty and power - tornadoes, volcanic eruption, tsunamis, earthquakes and other manifestations of the natural world.
