The weather is changing. You are hearing that if winter comes, the risk of flu and Covid-19 will be higher. In the season between the end of monsoon and the arrival of winter, find out why the weather on earth changes?

In a nutshell, weather changes due to the tilt of the Earth Axis. Most of the year, the sunlight falls on different parts of the earth. That is, when the North Pole is tilted towards the sun, it is summer in the northern part and when it is tilted to the south pole, it is hot in the southern hemisphere. But there are other aspects to this answer. There are some misconceptions associated with this question. Also, know how many questions and answers are available to you on the pretext of answering this question.

Why is the distance of the Earth from the sun?

There is a belief that the summer season is because the distance from the sun to the earth decreases at that time and the winter season is such that the distance increases. Although this concept sounds good but why is it not good? Let’s understand what science says.

It is true that the orbit of our earth is not a complete circle. It is slightly flattened on one side. At certain times of the year the earth is really a little closer to the sun, and at other times the distance from the sun increases. But if you look at the distance between the sun and the earth, being a little closer or farther away from the earth revolving in orbit does not make much difference. That is, it does not matter if the weather changes.

From top to bottom of the earth, the orbit of the earth in the center is like an imaginary pole. Assume that the earth is revolving around this one pole, on a complete revolution we see the time of day and night. The seasons change because the pole of the orbit is not straight. That bends a little here and there.

But why this inclination?

Long, long ago, when the earth was very young, it is believed that something very heavy hit the earth. Due to this shock, the earth began to rotate with a slight tilt instead of rotating straight up and down in its orbit. Now what was this big heavy thing? Do scientists know more about this?

Yes, it is believed that there was a planet in the early solar system about 4.5 billion years ago, which collided with our Earth. The collision caused a huge amount of dust and debris to reach Earth orbit. Many scientists believe that over time this is what appeared as the Earth's moon.

However, due to this inclination of the earth, the seasons change here. If the relationship between the earth and the sun is understood in every season, then the summer season is on the part of the earth where the sun is shining the most and the winter is happening there, due to the inclination where these lights have an angle Is arriving with. Throughout the year, sometimes the North Pole is tilted towards the sun, sometimes the South Pole.
