Explain the reason for the changing seasons.

As everyone knows, the Earth revolves around the Sun, it is generally believed that this is the reason for the change of seasons, however, the main reason is the Earth’s axis, because the Earth also revolves around its own axis. Due to the fact that the axis is tilted, we get a change of seasons. If the axis were at right angles, then the change of seasons would not take place, and all days would be the same. The axis is always directed towards the polar stars, as a result of which at different times of the year the earth exposes its surface in different ways to the sun’s rays.
