Day and Night

How day and night works

We have day and night because of Earth’s rotation.

First, the earth is always spinning on its axis which is an invisible line that goes through the North Pole and the South Pole.

In fact the Earth spins around its axis like a top, this movement is called the Earth’s rotation, the Earth’s rotation is what gives us day and night.

In addition while the Earth is spinning on its axis it also orbits or revolves around the sun. This movement is called revolution one whole orbit around the sun is called a revolution.

Lastly one side of the Earth is the Northern hemisphere and the opposite side is the Southern hemisphere.

This is how day and night works.
