Because there is No GRAVITY!
Well... yes and no...
Yes: Solar wind erodes the lunar surface but the effect is almost unnoticeable.
No: The moon has no atmosphere so there's no weather to cause 'typical' erosion.
Because there isn't Gravity
There is no wind or rain
There is no erosion from wind or water.
There is no erosion on the moon and mercury to erase the impact sites.
No atmosphere, no rain, no wind, no erosion.
because there is no weather on the moon. there's no air, no water, no life whatsoever. the only cause of surface changes on the moon are meteors and astronauts
it doesn't happen on the moon ... there no wind , water or any thing else that causes erosion on the moon :)
No weather on Moon.
Erosion can not happen on the moon, because there is no wind or clouds in the atmosphere.
There is no atmosphere on the Moon and no large bodies of water to cause any forms of erosion, so there is no erosion like on Earth.
No because there is no wind or water on the moon
There is no wind or rain
No because there is no wind or water on the moon
There is deposition - from the impact of meteors colliding with the moon.
Not as you are used to on Earth surface. Erosion is caused mainly by water and air movement, which do not exist on the Moon's surface. However, seismic activity and impacts from asteroids may cause effects not dissimilar to erosion.
Can't happen. Weathering takes air in motion (wind), and erosion takes water in motion, and there's none of either on the moon.
There is no erosion on the moon, except perhaps from the impact from meteorites knocking things around. There is no liquid nor is there an atmosphere to erode anything.
because the moon has no oxygen and water to have weathering or erosion
