Because most meteors break up in the atmosphere before they can hit the ground, or are so small by the time they do that they don't leave a crater. Also the weather (wind and water) erodes what craters there are fairly quickly.

The moon, however, has no atmosphere, so it's constantly poc-marked by meteoroids, and the craters last forever, until they're changed by something else, usually another meteoroid.

AnswerMost certainly the atmosphere helps, but the other conclusion from the evidence would be that the earth is not as old as claimed. The amount of cosmic dust, given the known rate of accumulation, is also too small and also supports an earth much younger than theorized. AnswerAnother possibility, generally the most widely held view, is that there have been many crater causing events on the earth, and processes of erosion have destroyed or eliminated some of them. There are some extremely large craters on earth, and some would not even be visible in a plane or with satellite imagery, unless special probes are used. Also, the moon and the other planets, particularly our giant neighbor Jupiter, have diverted many objects that might otherwise have collided with earth. We witnessed such an event just a few years ago when a comet crashed into Jupiter, leaving a gash in Jupiter's gaseous surface roughly the size of earth itself.

We also have to remember that earth is the only planet we know of that has a vast and immensely powerful water cycle. Deposited dust has been laid down, percolated into soil, turned into rock and other kinds of deposits, and none of these processes are observed on any other planet or moon. Some argued that the moon missions would be a spectacular disaster because the lander would sink into several meters of accumulated space dust. That did not happen.

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.


Names of craters that hit the Earth?

What evidence indicates that catastrophic impacts have occurred in the solar system?

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.

Why aren't we able to see most craters on the Earth?

Craters are eroded away by weather, earthquakes, living things, etc.


Why do you see seven impact craters on the moon but few on earth?

sorry i really dont know im a child and im trying to find that out for school. sorry for the inconvince


Why can we see the craters of the moon so clearly from earth?

We can see the craters of the moon clearly from Earth because the moon has no atmosphere to erode them, so they remain preserved. When the sun shines on the moon's surface at an angle, it creates long shadows that make the craters stand out more prominently, enhancing their visibility from Earth.


Can you see craters on the moon from earth?

No. Most of the impact craters that have formed on Earth have been destroyed and buried by geologic processes, processes that the moon lacks. While some recent impact craters on Earth remain visible on the surface, they are too small to be seen from the moon.


Why are impact craters on Earth harder to see than those on Mercury or the Moon?

Unlike Mercury of the moon, Earth is geologically active. Erosion, deposition, and plate tectonics have buried or destroyed most of Earth's craters.


Why can we see craters on the moon so clearly from Earth?

In astronomical terms the moon is very close to Earth, much closer than anything else. Other astronomical bodies have similar cratering but are too far away for us to see them. Second, the moon is geologically dead. There are no processes on the moon's surface to destroy or bury the craters on the moon as has happened to Earth's craters.


Where are craters are found?

By name, Craters of Diamonds State Park is located in USA, in Arkansas. All diamonds are exploded to the earth's surface from volcanic pipes, which when mined turn into craters. You can see these craters in Africa, Canada, Russia, Brazil, India and Australia.


Why do you see impact craters on mercury and the moon but not so much on earth?

Earth has a thicker atmosphere that burns up most of the smaller meteoroids before they can reach the surface, whereas Mercury and the Moon have very thin or no atmosphere to protect them. As a result, these bodies are more vulnerable to impacts from space debris, creating visible craters. Additionally, Earth's active geological processes, such as erosion and tectonic activity, continually reshape the surface and can erase evidence of impact craters over time.
