Eclipse

On the recent Eclipses at July 11, it was amazing too see the Sun being blocked out by the moon. This would be because the moon and the sun are in a direct alignment to the Earth. This is a very rare phenomenon that happens around 4 times every year. In my powerpoint slide I would be talking more about it.Here is the link to my powerpoint: http://www.docstoc.com/docs/54383666/Eclipses
