What is the giant impact hypothesis for the origin of Earths moon?
The theory is this: not long after the earth was born, there was still alot of junk left over from the creation of the solar system. One of these pieces of junk–also known as meteors, slammed into the earth, tearing a huge chunk out of the earth. The approximate size of the Pacific Ocean. The material, along with the meteor, spun around in the area around the earth, was caught in the earth’s gravitational field and eventually formed the moon. Some of the material naturally returned to earth. But the bulk of the material formed the moon. Which is why the moon and the earth are so much alike, as far as geology is concerned.
