Earth and Its Movements Related to the Sun

I learned that we live on a planet called Earth. Earth is always moving. It may not seem like it to us but the earth is moving very fast. The Earth spins on its axis. This spinning is called rotation. It takes 24 hours for the Earth to make one full rotation. One rotation is also called a day.
The Earth also moves around the Sun. When the Earth moves around the Sun it is called a revolution. One revolution around the Sun takes 365 days. One revolution is called a year.
