How we rejoice at the change of seasons, and do not even suspect how exactly this simple, at first glance happens, but such a serious process. So let’s fill this gap in our knowledge.
The offensive of spring
As we all know, a year is divided into four seasons – this is spring, summer, autumn and winter. Spring is a very pleasant time, this is the time when we take off our boring and heavy clothes, and rejoice at a slightly warmed breeze, and how the sun begins to warm our face.
How is the change of seasons
Spring is generally such a time of the year that all living things begin to awaken. The grass begins to turn green, the kidneys bloom on the trees and leaves appear. In a word, the earth begins to wake up from deep winter hibernation.
This is all because, thanks to the inclination of the earth, its northern hemisphere is inclined to the sun, which is why it becomes warmer on this part of the planet. Our planet makes a complete revolution around the sun in one year. At the same time, her orbit is not entirely circular, but slightly elongated – elliptical. Thanks to this, in the spring, the Earth also turns out to be 3% closer to the sun than before. And it is precisely because of these 3% inclination towards the Sun in the Northern Hemisphere that such a pleasant phenomenon is taking place as spring. By the way, in the southern hemisphere at this time, autumn occurs.
Summer time
After spring has prepared nature for the next period, summer comes to replace it. Clearings begin to be covered with various colors, berries.
How is the change of seasons
People are happy to go on vacation, closer to nature. In the summer, it becomes so warm that the sand on the beach becomes very hot, and the water is warm. On earth it becomes warmer, because it, as it moves, has reached the closest point to the sun. In addition, thanks to the inclination of the earth’s axis, the sun’s rays fall almost vertically, warming the surface. Therefore, in the summer we see the sun high, almost at the zenith, and it warms stronger.
Naturally, the days have become much longer, and the nights are now much warm. In the summer in the Northern Hemisphere at night, it was almost light, and all this – because of the not large inclination of the earth.
Autumn
Autumn is no less beautiful than summer, it has absorbed so many natural colors. All plants begin to change their color, the trees turn yellow, like the Sun itself.
How the seasons change
The arrival of autumn is due to the fact that the globe gradually began to move away from the Sun. The days begin to rapidly shorten, it becomes cooler, and at night the frosts begin to slowly press down. The entire surface of the Earth is covered with a large layer of yellow and red leaves.
The northern hemisphere of the Earth begins to “turn away” from the Sun, so it appears lower and lower every day above the horizon. The sunlight is no longer so bright, even in the daytime, and small snow fluffs gradually begin to fly in places.
Snow drift time
So it’s time for snowstorms and bitter frosts. This is the time when the surface of the earth is covered with a large layer of snow. Just at this time, the earth moves away from the sun to the maximum distance. Due to the tilt of the earth’s axis, the sun’s rays are seen low on the horizon. At the same time, the Sun rises later and hides earlier – the day becomes shorter, and the sun’s rays practically do not warm. The nights, on the contrary, are getting longer, but the night sky is so clear that it even feels like the stars have become closer.
How the seasons change
So just a slightly elongated orbit of the planet and a slight tilt of its axis gave us as many as four different seasons. As the Earth and Sun approach and recede, we can observe a smooth change of seasons. Only in tropical latitudes is this phenomenon so weakly expressed that it is almost not felt. The seasons are not only beautiful, but also make our life more diverse. It is not for nothing that the inhabitants of the equator, who have never seen snow, envy us, the inhabitants of higher latitudes.
