How often do craters form?
due to the striking of the meteors on moon
Why are there fewer craters on earth compared to the moon?
Earth is geologically active and has an atmosphere and water. The moon has none of these. The atmosphere protects Earth from smaller objects, but not from larger ones. When craters do form on Earth, wind water, and ice erode them away and often bury them in sediment. What is left of the craters may be destroyed by plate tectonics as rocks are folded, faulted, or sink into the mantle. Other than asteroids and comet impacts, the moon's surface has changed little since it first formed.
What are 3 reasons why most craters left on earth are no longer visible?
Erosion: One of the primary reasons why many craters on Earth are no longer visible is due to erosion. Natural processes like wind, water, and ice can wear down the surface of the Earth over time, gradually filling in or smoothing out craters. For example, rainwater can erode the edges of craters, causing them to lose their distinct shape and eventually become indistinguishable from the surrounding terrain. In regions with active geological activity, such as tectonic activity or volcanic processes, the surface can be reshaped relatively quickly, further obscuring the features of old craters. Vegetation and Biological Activity: The growth of vegetation and the activities of various organisms can also contribute to the disappearance of craters. Plant roots can penetrate into the soil, breaking apart and filling in the depressions left by impacts. Burrowing animals and insects can further disturb the terrain, altering the appearance of craters over time. In some cases, the growth of forests or other dense vegetation can completely cover up smaller craters, making them difficult to detect. Geological Processes: Earth's dynamic geological processes can gradually bury or alter the appearance of craters. Sediment deposition from rivers, oceans, and glaciers can accumulate over time, burying craters and changing the landscape. Earthquakes, volcanic activity, and tectonic movements can also reshape the surface, potentially concealing or altering the appearance of craters. Additionally, processes like landslides and sedimentary layering can obscure craters by covering them with new materials. These factors, often working in combination, contribute to the fading or complete disappearance of many craters on Earth's surface over geological time scales. However, larger and more recent impact craters can still be visible if they haven't been significantly affected by these processes.

Why doesn't the Earth have as many craters as the moon?
The Earth has a atmosphere that shields meteors from hitting Earth and creating craters. The moon has no atmosphere, so meteors hit it often, creating craters.If the earth had no atmosphere where many small meteors would vaporize , or there was no wind or rain or tectonic plate movement, and other geological forces that would eventually cover up such impact sites, and of course no seas, or plant life then earth woulld ovbiously have many more craters than the moon as it's a bigger target. There are well over 100 known sites on earth and more deemed as probable.Because the moon has no atmosphere, it has no protection from meteors, asteroids or meteorites. The last layer in earths atmosphere protects us from that. So that's why earth doesn't have craters.The earth's atmosphere (air), through friction, burns up most of the many meteors that fall to earth. The moon has no atmosphere.The Earth has an atmosphere that burns up many of the items. It has to be pretty big to make it to the surface. And the Earth has weather, which erodes and erases the evidence of many of the strikes that the Earth has had.
What are the Physical Features of the Moon?
AnswerThe physical features of the moon include maria - smooth flat plains of basaltic lava, craters, highlands - which make up most of the lunar surface, rills, ejecta - found around an impact crater, and of course, the lunar regolith, a soil-like blanket of fine particles which covers the lunar surface.
What might be responsible for most of the craters on earth's moon?
The vast majority of lunar craters are caused by meteor impacts.
Why isn't earth covered in craters?
Earth is geologically active and has moving air,water, and ice on its surface. As a result, plate tectonics and weathering largely destroy most impact craters within a few million years, and most of what is left is often buried under sediment. Craters do exist on Earth, but apart from the youngest, they are not readily apparent.

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.
How does a planet's atmosphere affect its number of impact craters?
An atmosphere will lessen both the amount and size of impact craters by burning meteoroids so they get smaller or even disappear entirely. If there is no atmosphere, the object will simply hit the planet or moon with no reduction in its size. Earth's atmosphere does this because the air molecules create friction when the meteoroid passes through it. The friction is hot enough to burn the meteoroid up entirely or at least down in size. An atmosphere means fewer and smaller meteoroids. (When a meteoroid does make it to the ground, it then is called a meteorite.)
How does a mare differ from a crater?
A mare is a smooth, dark area on the surface of the moon. A crater is a huge hole caused by a meteor or meteorite. Hope that satisfies you! If not come back soon and i'll have another answer.
What cause craders?
If you mean craters as in the holes in the earth, then they are formed by meteors crashing into earth. If you didn't mean that, I need to start learning a bit more vocab.answ2. Volcanoes also often have craters at their summit.[Strictly, meteors are the seen phenomena, meteorites are the ones that land.]

Does a hurricane have a calm center?
Quite often, yes. This center is called the eye of the storm.
Are there any meteorite craters at Antarctica?
Since 98% of the continent is covered with an ice sheet, it's impossible to tell whether or not there are any craters in the landscape under the ice sheet. Antarctica, however, is a rich geography for meteorites. Often they are found because their composition attracts the sun and melts the ice that surrounds them.
What is the result of a collision with a large object from space is often an impact?
You've definitely got that right ! There's no debating the fact that the result of a collision is often an impact.
