How we have day and night

In school recently our topic has been space and today I am going to tell you about how we have day and night. We have night and day because the earth is always rotating.if  the earth did not rotate then we would never have day and night.

 Day time is when half of the earth is facing the sun whereas night time is when the other half  of the earth is facing the other side of the sun.

thanks again from Maheen
