find out how we get day and night

We get day and night because 50% of the earth is in night, and the other 50% is in the day time.
Do you know why?

I will tell you why. The earth has gravity which causes it to rotate. As the earth rotates half of it has day, but if it does one half turn the day side will have night.

It is the same with the night side. That means the earth`s two halves take turn to have day and night.
