Why do we have night and day?
We have day and night because the earth’s rotation.
Firstly, the northern hemisphere faces the sun that’s Day and the southern hemisphere faces to space that’s Night.In addition the earth is spinning on its axis, the axis is a imaginary line from the north pole to the south pole.
Secondly, the earth takes 365 days to make a revolution that makes a year.
Lastly, the sun makes day because its a star.
