1. Rotation: Earth spins on its axis, completing one rotation approximately every 24 hours. This rotation is responsible for day and night.

2. Revolution: Earth orbits the Sun in an elliptical path, completing one revolution approximately every 365.25 days. This revolution is responsible for the seasons.

3. Precession: The Earth's axis of rotation slowly wobbles like a spinning top, completing one full wobble cycle approximately every 26,000 years. This wobble is responsible for the slow change in the position of the celestial poles over time.
