Group 2 Day And Night
th?id=I4594610558140625&pid=1.5Day and night are both interesting things. Day is caused by the earth spinning so part of it faces the sun. Night is caused by the oposite when the sun is facing the other side of the planet. The moon constantly orbits the earth and at night the moon glows because the moon is reflecting the sun. When you look at the sun it looks like it is moving but actually it is the earth moving on its axis. Half of the world is having day at any one time
