Night+and+Day


 * Why Do We Have Night and Day on Earth? **

Planet Earth moves in two distinct ways:

1. It orbits (or revolves) around the sun. 2. It rotates (or spins) on its axis.



The Sun does not orbit but remains stationary. That means that the Sun stays in place. Because Earth spins around its axis, not all parts of Earth are facing the Sun at any given time.

Earth rotates on its axis in a counter clockwise (or West to East) direction. Because Earth moves from West to East, the sun always appears to rise in the East.

You may even have heard the saying, "The sun always rises in the East and sets in the West." That means when we look East in the morning, we can see the sun rising in the sky. When we look West, we see it setting in that direction.

Silly but True:  Some people even try to find jobs where they can drive West in the morning so they don't have to have the sun in their eyes. Driving north or south does not make much difference. Also, did you know that sun glare is a very serious problem and causes many traffic accidents?
