While most craters left by ancient impacts on Earth have been erased by erosion and other geologic processes, the Moons craters are still largely intact and visible. 2) Most meteorites are denser than the average Earth rock. When the surface of the meteorite begins to melt during entry into the atmosphere, some areas of the meteorites are eroded by the melting more than others, almost like someone is taking little scoops of material out. The kamacite crystals revealed by this
