The erosion on Earth caused the craters to disappear.It also caused them to not get seen by anything and it is gone. bye bye

Why isn't the earth covered with craters?
The Earth isn't covered in as many craters as other planets is due to water and wind erosion. Plant and wildlife also cover up some craters making them less visible.
What evidence indicates that catastrophic impacts have occurred in the solar systems past?
Many impact craters are visible on many planets and satellites of planets. The moon is a perfect example, it is covered with craters, some of which we can see from Earth even without a telescope. We do have a few impact craters that have survived here on Earth, as well, even though the weather on Earth, over long periods of time, tends to smooth away craters.
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 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.
How are the craters on mars caused?
The craters are formed by a large object such as an asteroid or a comet. When these large objets hit the surface they form holes. Known as craters. Craters can be many shapes and sizes depending on the object. That's how craters are formed. Mars has a much thinner atmosphere than Earth, so more objects reach the Martian surface intact, and the lack of water, glaciers, and plate tectonic mean the craters last longer than they do on Earth.

Why does earth lack craters?
Earth does have impact craters, but it has much few than the moon or Mercury and many of them are not readily visible. The main reason is that Earth has many active geologic processes that renew and change its surface, burying and destroying impact craters. If an impact crater on Earth is clearly visible then it probably formed quite recently in geologic history. Many of the impact craters on the moon and Mercury are billions of years old, dating to when the solar system was young and large asteroid impacts were far more common than they are now. Very little of Earth's crust from that time remains intact. By contrast craters on Earth that are tens of millions of years old are not readily visible.

What happened to all of earths craters?
Erosion and coverage. Weather, rain, floods, wind, earthquakes, plants and so on have eroded much of the craters that were on earth. Vegetation helps to disguise earth's craters as well. Since Earth has had an atmosphere for quite some time, many meteors burn up in the atmosphere before they would hit earth and leave a crater. Now only some of the largest craters are visible.

How many craters Earth?
There are a huge number of craters on the Earth, including very small impact sites. There are about 65 named and documented craters on the planet.
Why are there so many craters on the moon and mars compared to earth?
Mars and our moon do not have dense atmospheres where many of the smaller probable impacts break up prior to reaching terra firma's earth. Second the earth's massive tectonic shifts mold the earth slowly and the actions of wind, water, and life break down geologic features, so many visible craters are erased.

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 does the moon have more surface craters than the Earth does?
I'm no expert but id guess that earth (being a larger target) has been hit more then mercury. (here is where the guessing ends) but mercury is devoid of water Ware as earth has lots. their was once a time where earth was covered with impact craters. but over rain eroded them away. mercury has no rain so the craters will stay their for millions of years
