Rotation is the circular movement of an object around its own axis, while revolution is the movement of an object around another object. The Earth rotates on its axis once every 24 hours, causing day and night, and revolves around the Sun once every 365 days, causing changes in seasons. The Moon also rotates on its axis once every 28 days and revolves around the Earth once every 28 days.
