Answer:
1.Following are some of the effects of Earth’s rotation:
It causes the bulging of the Earth at the Equator.
It causes days and nights.
It causes tides twice a day.
2.Days and nights are caused by the rotation of the Earth around its own axis. Due to the spherical shape of the Earth, only one half of the Earth gets light and heat from the Sun at a particular time. The portion of the Earth that receives sunlight is known as day, while the other portion is known as night.
3.Following are the factors responsible for the change of seasons:
Rotation of the Earth around its axis
Revolution of the Earth around the Sun
Inclination of the Earth’s axis
The Earth moves in an elliptical orbit and completes one revolution in 365 1/4 days. The axis of the Earth is tilted along the orbital plane and this tilt causes seasons. Because of this reason, different parts of the Earth receive different amounts of sunlight at different times of the year and hence experience change in seasons. When the axis faces the Sun, the respective hemisphere experiences summer. When the axis faces away from the Sun, the respective hemisphere experiences winter.

The above diagram shows how seasons are caused.
