                  2 Climate and the Seasons.

Sub-Topic 1: Eclipse

Sun is a large luminous body from which light shines on to the earth and the moon. Because of the movement of the earth and the moon, it is possible for one to shield (Eclipse) the other from the sun.

There are three types of eclipse:

1.  An eclipse of the moon:   this is formed when the earth comes between the sun and the moon; the moon is in the shadow of the earth.

2.   An eclipse of the sun:   This is formed when the moon passes between the earth and the sun, the shadow of the moon falls on parts of the earth.

3.   Annular eclipse:   A times when the moon is so far away from the earth that no region of total shadow falls on the earth. The moon is then observed against the circular sun.
