Why does erosion happen on earth and not on moon?

Answer 1

There is considerable erosion on the Moon, just not the same as on Earth. On Earth, erosion is caused by air, water, and geologic processes. (Air and water transport of solids is included and important.) On the Moon, there is no wind-blown sand or rushing streams, but there is significant erosion, resulting in a layer of dust, of varying thickness, on the entire surface. It may not move around as much as on Earth. The erosive forces on the Moon : * Heating and cooling (cracks and chemically changes rocks, and can clump dust electrostatically ; where ice is present, it can melt, expand, or contract) * Solar wind (there is no atmosphere to impede high-speed ions and particles) * Meteor impacts and micro-meteoroids (again, no atmosphere to stop them)

Answer 2

There is no erosion on the moon because there is no wind or water to cause it. The moon does not have plate tectonics because its mantle is not hot enough to support the movement of the crust.

Answer 3

Erosion DOES happen on the Moon, it is just that the mechanism - ablation by the solar wind and meteorite impact, is a much slower process.

On earth the Atmosphere and Hydrosphere, energized by solar irradiation effect a much faster erosion regime.

Answer 4

It's the other way around I think. The Earth has "weather", etc.

The Moon has no wind or rain, etc.

Answer 5

because there are no atmosthere
