Question

how are day and night caused???

Answer 1

Very good question. The earth revolves round the sun and rotates round its own axis. The rotation of the earth causes day and night. which gives us some time to take a break. The part of the earth which faces the sun experiences the day time whereas the part away from sun gets no sun light and hence the night.The axis of earth's rotation is tilted at 23.5 degrees.

HOPE THIS HELPS
