The amount of time it takes for a single trip around the sun.
What’s the shape of the Earth’s orbit?
It’s has an eliptical shape.
What’s the reason we have seasons?
The Earth’s spin, tilt, and rotation around the sun is the reason for the seasons.
Why do planet’s orbit the Sun?
Because it’s really big.
Why is the Sun important?
It makes plants produce photosynthesis.
What’s the name of the theory of the Moon’s formation?
