How did the moon form?
Question asked by: knowitall
Theories abound. The most widely accepted thought at present is that some massive impact on earth in its very formative days was so violent that it sent a chunk of earth rock flying out into space, and this became the moon. Certainly if true this was very fortuitous for life on earth in the long run, as the moon has many effects on the earth that are beneficial for life, e.g. tides.
