List the four seasons.
- Winter
- Summer
- Spring

Why do we have seasons?
They are caused by the Earth’s tilt on its axis and its revolution around the Sun.
What causes the phases of the moon?
They are caused by the Sun’s rays and the Earth’s shadow as the Earth and Moon rotate and revolve around the sun.
What are the four phases of the moon?
- New
- Crescent
- Gibbous
- Full
