One of the causes of the occurrence of the four seasons

The answer is:

• Earth’s rotation around the sun.
• The inclination of the Earth’s axis is stable.

One of the reasons for the occurrence of the four seasons is the rotation of the earth around the sun. This rotation causes the earth to tilt on its axis by 23 and a half degrees, which leads to a difference in the angle of incidence of the sun’s rays on different parts of the earth. This difference in angle of incidence causes the four distinct seasons—spring, summer, fall, and winter. Moreover, this rotation also determines the duration of each season, with some parts of the world having longer summers and shorter winters. In conclusion, the Earth’s rotation around the Sun is a major factor in determining the four seasons.
