Briefly explain the craters found on Earth's moon
What will be an ideal response?
Wherever you go on the Moon, you will find craters. The highlands on the Moon are marked heavily by craters, but the smooth lowlands contain fewer craters. The craters on the Moon were formed by impacts, as evidenced by their distinguishing characteristics such as shape and the material (ejecta) they have spread across the Moon's surface.The highlands are composed of low-density rock, for example, anorthosite, a light-colored rock that contributes to the highlands' bright contrast with the dark maria and that would be among the first material to solidify and float to the top of molten rock. Many rocks found on the Moon are breccias, made up of fragments of broken rock cemented together under pressure.
