Answer 1

Answer:

The Earth rotates on its own axis and it is tilted at an angle of 23.5° with respect to its orbital plane; this causes the occurrence of seasons. The revolution of the Earth around the Sun, which requires 365 days and 6 hours, in an elliptical orbit also causes the change in seasons.
