There are countless craters on the surface of the moon, but why are there so few craters on the earth?

The moon is a satellite of the earth. There are many legends about the moon since ancient times. The ancients had different feelings about the moon. They regard the moon as a shrine and think that people live there. Later, with the invention of astronomical telescope, people can finally observe the moon clearly. Only then did I find that the moon was desolate and there was nothing. On the contrary, the surface of the moon is covered with countless craters.

Every planet has been hit by a meteorite, and naturally there are craters, but to say which planet has a large number of craters, the moon is well-deserved from what can be observed. How big is the crater of the moon? At present, scientists do not have accurate figures, but conservative estimates are also above 65438+ 10,000. With so many craters, we can see what kind of disasters the moon suffered in history.

Maybe a friend asked, the earth is so close to the moon that it is much bigger than the moon. With such a big goal, why can't we see many craters on the earth? Is it because the earth is so lucky that meteorites go around the earth? Three reasons can be roughly analyzed here.

The first reason is that the earth has an atmosphere, and meteorites will burn through the earth's atmosphere by friction, and small meteorites will burn out when they hit the ground. Larger meteorites will be grilled very little after passing through the atmosphere and have little impact on the ground. There is no atmosphere on the moon. When the meteorite comes, it hits directly, and naturally there are more craters.

The second reason is that the earth is a living planet with very active geological activities. The crater left by the impact of meteorites on the earth, with the passage of time, with the influence of weather activities and geological movements, the surface of the crater has been rubbed and weathered by water, and over time, the crater has naturally disappeared. This is also one reason why there are few pits and stone pits that can be preserved on the earth.

The third reason is to thank the moon, which is the satellite and guardian of the earth. It stands in front of the earth. When meteorites hit the earth and the moon, the moon will stand in front, and the meteorite will naturally hit the moon first, and the earth will be spared. This may be an important reason why meteorites rarely encounter attacks in the history of the earth.

The moon is the companion of the earth and our comrade-in-arms. In the future, human beings will definitely establish a living base on the moon, and then they will emigrate to live on the moon.
