According to ISRO, the Moon has been continuously bombarded by meteorites, asteroids and comets since its formation. This has resulted in the formation of innumerable impact craters that form the most distinct geographic features on its surface.
Impact craters are approximately circular depressions on the surface of the moon, ranging from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins.
“In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain,” ISRO said.
The study of the nature, size, distribution and composition of impact craters and associated ejecta (material that gets thrown out on an impact) features reveal valuable information about the origin and evolution of craters.Read More..
