How the four season forms?

Answer 1

The seasons are formed by the movement of the earth around the sun. Because the earth's axis is tilted, but not tilted toward the sun, as it moves around different portions receive more direct sunlight during different times of the year.

Answer 2

The four seasons are caused by the tilt of Earth's axis as it orbits the sun. During different times of the year, different parts of the Earth receive more or less direct sunlight, creating the variations in temperature and weather that we experience as the seasons change.

Answer 3

The four seasons are formed based on the sun's position to the Earth. This is just what happens due to position of the location under four seasons.
