Images provide clues about a plant's geologic processes and history.
Impact craters are caused when a bolide collides with a planet. A crater s six and features depend on the mass and velocity of the bolide. Impact craters provide insights into the age and geology of a planet's surface. The Martian surface contains thousands of impact craters because, unlike Earth , Mars has a stable crust, low erosion rate and no active sources of lava. So, impact craters on Mars are not obliterated as they are on Earth.
