By Ethan P
It is day when our part of Earth is facing the sun.
It is night when our part of the earth is facing away from the sun.
The earth spins very slowly and it take 1 day for a full spin.
We do not fall off the earth because gravity pulls us to the center of the earth.
A rotation is when the earth spins 1 circle which is 1 day.
