Types of Solar Eclipses1. Total Solar Eclipses occur when the umbra of the Moon's
shadow touches a region on the surface of the Earth. 2. Partial Solar Eclipses occur when the penumbra of the
Moon's shadow passes over a region on the Earth's surface.
3. Annular Solar Eclipses occur when a region on the Earth's surface is in line with the umbra, but the distances are such that the tip of the umbra does not reach the Earth's surface.

Evidence from the composition (what it is made of) shows that the moon was formed by a collision of an object the size of Mars hitting the earth. The material that blasted into space began to orbit the earth and eventually collected up to form the moon.
