Why does a moon have more craters than earth?
It has more craters because the earth has an atmosphere vs the moon which does not the atmosphere creates friction on the asteroid which makes it burn up into smaller rocks that can be seen in a meteor shower these rock burn up before they hit he ground.
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.
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.
Why do planets like mercury have many more crater holes then earth?
Earth has an atmosphere unlike Mercury. Since Earth has an atmosphere, the meteriors burn up before they hit the ground. Mercury has little to no atmosphere so the meteriors are free to hit the ground and make craters.
What is the relationship between the number of craters and the thickness of a planet's atmosphere?
The thinner the atmosphere, the more craters the planet has. Planets with thicker atmospheres burn up most asteroids before they hit the ground.
Why are there thousands of craters on the moon?
The moon doesn't have an atmosphere, so meteorites hit the surface and create the craters. Earth's atmosphere causes most meteorites to burn up due to air friction before the meteorite can crash on to the surface. A 'shooting-star' is a meteorite burning up in the sky.
Do most meteors burn up before they hit the earth?
Yes.
What effects are caused when meteors hit Mars?
The same as if they hit the Earth, however it must be noted that the gravity on Mars is not so strong as Earth's, plus the air is a lot thinner. So perhaps bigger craters because there is less atmosphere around to burn up the meteor before it turns into a meteorite.
What are two reasons why earth doesn't look all cratered like the moon when we get hit more often by debris?
Earth has an atmosphere, so we have erosion and weathering that softens the edges of craters and wears them away. The atmosphere also protects us from many of the smaller objects, as they burn up from friction before they reach the surface.Here is a good WikiPedia article on craters we know about on Earth.
Names of craters that hit the Earth?

Why does Mars have crators?
Mars has craters because the atmosphere is too thin for meteors to burn up in, (as most do before they hit the earth). There are also craters on Mars, because there is almost no erosion on Mars, as there is on earth to cover up the evidence of impact.
Why do most meteors burn up before the hit the earth?
Most meteors burn up before they hit the earth. Have you ever wondered why? Well, most burn up because they travel so fast. The speed catches anything in its path on fire.
