Solar System

My best understandings about...

1. How the phases of the moon occur... As Earth rotates around the sun, the moon rotates around Earth. The phases are formed by how much sunlight hits the moon as it rotates around Earth.

2. What causes the seasons... Seasons are caused by Earth's tilt. Earth rotates around the sun at the same angle. As Earth rotates around the sun, seasons are formed.

3. What causes a lunar eclipse... A lunar eclipse is caused by the alignment of the sun, Earth, and the moon.
