How is revolution of the earth responsible for change in season?

These revolutions of the Earth, refer specifically to its translation movement, which consists of the elliptical orbit that describes the Earth around the Sun.

So, a complete revolution around the Sun occurs every 365 days, 5 hours, 48 minutes and about 46 seconds. It is thanks to this movement and that the Earth's axis is tilted with respect to the plane of its orbit about , that the four seasons of the year exist.

That is why some regions receive different amounts of sunlight according to the seasons of the year. These variations are more evident near the poles and softer or imperceptible in the tropics (near the equator). This explains the fact that while in the northern hemisphere it is summer and there are high temperatures (because the Sunlight incides more perpendicularly in this area during this season), in the southern hemisphere it is winter and very low temperatures are recorded, and vice versa.

However, as the Earth continues its translational movement, the solar radiation affects more obliquely, as is the case of the spring and summer seasons.

It should be noted that near the equator, as previously mentioned, these changes are not very noticeable and the temperature tends to be more stable, with only two seasons: rain and drought.
