The Earth rotates on its own axis, causing one part to face the sun (day) while the other part faces away (night).
Changing Seasons
As the Earth revolves around the sun, different regions experience changes in weather, leading to seasons like summer, winter, and monsoon.
Animal Migration
Many birds and animals travel long distances during specific times of the year to find food, warmth, or suitable breeding grounds.
