SOLAR SYSTEM

Detailed explanation-1: -Because of tectonics, the surface of Earth is recycled many times throughout its long history. As a result, very few rocks on Earth are as old as the rocks on the Moon. The Moon has not had tectonics for billions of years. That’s a lot more time for craters to form and stay put.

Detailed explanation-2: -So why are there so few craters on Earth? NASA notes that Earth is equipped with three processes that eat up craters relatively quickly: erosion, tectonics, and volcanism. These forces leave only the largest scars from meteorites or asteroids-unlike, say, the moon, which can’t gobble up craters.

Detailed explanation-3: -The moon has so many more craters than Earth because the moon has no processes of weather or erosion to remove them. Earth has precipitation, wind and water erosion that change the landscape over time. These processes can erase any evidence of craters that have occurred.

Detailed explanation-4: -One reason the moon has craters because it gets hit by objects, small pieces of rocks that come from outer space. These are pieces of asteroids, comets that are flying around in the solar system. When they hit the surface, there’s an impact. The moon has no atmosphere, and so even a tiny rock will create a crater.

Detailed explanation-5: -The moon’s surface is much more heavily cratered than Earth’s surface because ancient craters have already disappeared on Earth . They were worn away over time by water, wind, and other forces . Since the moon has no liquid water or atmosphere, its surface has changed very little .
