Earth is biologically active. Life - mainly vegetative - keeps filling the craters in.
Edit: in fact these are the main reasons, as far as I know :
1) Erosion caused by weather
2) Concealment by sediments
3) Renewal of the Earth's surface by tectonic plates.
What else can I help you with?
Why do you see many impact craters on the moon but not earth?
The Earth has weather patterns that have eroded most of the craters on Earth. The moon has no weather, therefore no erosion.
Why is the moon full of craters but the earth is not?
The Moon's surface is heavily cratered because of of meteor impacts. Meteors are able to more commonly strike the Moon's surface than the Earth's surface because the Moon's atmosphere is not as strong as the Earth's, so less meteors burn up in the Moon's atmosphere than they do in the Earth's atmospheres. So the craters are simply the result of heavy meteor impacts. Answer #2 The moon has no weather to erode craters. Speculation is that the earth has been hit at least as many times as the moon because of our greater mass. Wind, water, and plate tectonics wipe out the evidence on earth.
Why do you see so few craters on the earth compared to the moon?
The moon is hit by many more meteorites than Earth because it has no significant atmosphere to burn them up in. Also as the earths surface is continually changing, visible craters may be filled in, smoothed over or covered up.
Are there more craters on Mercury and the Moon than the Earth?
The surface of the Earth has been reworked over geological time and this has erased evidence for craters that have existed on the Earth. However all the inner planets and moons have been subject to the same rate of impactors and as Earth is larger, it is therefore likely that Earth has in fact received more impactors (and therefore had more total craters) than the Moon or Mercury. There are more craters now visible on the Moon and Mercury, but there were likely many more on the Earth over the same astronomical time. But craters on Earth have become less visible due to erosion and geologic activity - these processes are much more active on Earth than on the Moon or Mercury, which have less tectonic activity, no real atmosphere, and no liquid water.
Why are the craters on the moon all perfectly circular?
It can not be because the moon has no atmosphere or gravity....in fact many craters would then have a parabolical shape because all meteorites can not impact with the moon at an exact vertical angle. So why can it be? It is because the theories of the moon being part of a very young earth is simply not true. Earth with it's much stronger gravitational pull should attract far more meteorites away from the moon, had this been the case. Also, the moon, being so close to earth, is protected by the earth from meteorite strikes directly in line with the earth. Earth's gravity would not allow meteorites to hit the moon directly behind it. Missing earth, the meteorites will definitely not impact with the moon directly behind earth. Many craters are on the side of the moon facing earth, so how did these meteorites get past earth to stirke the moon exactly face on? Remember that the moon is in terms of the universe, very close to earth therefore earth is shielding the moon against many many meteorite strikes from directly behind earth itself. Sorry, but I can not answer this question!
How many sides of the moon are visibles?
near to the earth and cms if you want to add more
Why do you see many impact craters on the moon but not earth?
The Earth has weather patterns that have eroded most of the craters on Earth. The moon has no weather, therefore no erosion.
Does the moon has craters?
The moon has plenty of craters, many of which can be seen from Earth, with a good telescope or binoculars. The craters are there, because the moon has no atmosphere for the objects to burn up in, so all of them hit the moon.
Stuff that the moon has that the earth doesn't?
The moon has many craters, and it does not have the atmosphere that the Earth has. There are lunar seas known as maria on the moon.
Does only the moon have craters?
No, Earth has some craters, but not as many because Earth has an atmosphere to destroy or smallen meteors, but the moon does not, so it is hit by meteors more3 often.
Who used a telescope to discover craters on the moon?
Many of the larger craters on the moon can be seen from earth without a telescope, so nobody discovered craters on the moon with a telescope.
How many craters are in the moon.?
There are 375 craters in the moon.....
Why does the moon still have many craters when the Earth does not?
Craters tend to disappear on the Earth because of erosion caused by weather, and because of earthquakes. The moon has no air and therefore has no weather, and it also is not tectonically active.
What caused the moon to have many craters?
Meteorites. They hit the moon frequently, causing many craters.

Why does the moon has many craters but the Earth has few?
Earth is geologically active with volcanoes, tectonic plates, and has a substantial atmosphere, moving water, and glaciers. These forces are constantly changing Earth's surface. Impact craters get eroded, buried, and outright erased. The moon has no significant geologic activity, no atmosphere, and no water. As a result craters on the moon can remain almost untouched for billions of years.
Is there a way to figure out how many craters are on the moon?
isw there a way to figure how may craters are on the moon
