What causes day and night on the earth
Rotation of earth around its axis.
the rotation of the earth around the sun and how the earth is tilted on its axis and how it spins :) hope this helps :)
the earth rotates and the sun only shines on half of it and while it spins it moves into light or darkness....spin an orange or ball in front of a light and you will see what i mean
The earth revolving around the sun.
