A very interesting perspective. Different kinds of craters results from the intersection of different size impacts and different geological conditions prevailing at the time .
I wonder if that first big meteor would have come in at that angle. Anyway, very cool animation.
Comment on the front page of scienceblogs:
Many of the moon’s craters were formed 4 billion years ago on Greg Laden’s Blog.
