The major impacts that form large craters are rare events, occurring on Earth roughly every 100 million years. The last major impact was 65 million years ago (mya). Over such a long period of time, the forces of erosion, deposition, and plate tectonics can destroy or bury a crater. The remnants of the 65 mya impact crater, for example, are buried under more than a kilometer of sedimentary rock. Large impacts were more common when the solar system was young and many of the large craters on the moon date to that time, but almost none of Earth's crust from that time still exists.

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

There are relatively few craters identified on the surface of the Earth while there are thousands (millions) on the moon. It is hard to find one point on the moon that is not in one crater and there are craters in craters in craters. (See images in related link for Moon.) Obviously, the major reason behind this is that the craters that formed on the Earth eroded over time due to wind, rain and other natural factors which are nearly absent on the moon. Thus Earth's craters disappear over millions of years while the craters on the moon remain for billions of years. (The primary way a crater is made to disappear from the surface of the moon is by having another impact crater formed and the dust and debris from later impacts disturb or destroy or cover the original crater.)


Where are craters of diamonds 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 is it hard to find craters on the surface of earth?

Because of weather erosion. Earth has a thicker atmosphere than the moon, say, which has no atmosphere at all, and thus, no wind, water or rain to wash away the marks left by meteors or asteroids that hit the surface of the planet. Earth is hit by things all the time, but are washed or wiped away quickly by snow, rain, wind, etc.


What are the hole names?

What kind of minerals do you find in the interior of the earth?

minerals i dont know


Where would you look in the Solar System to find out how many meteors could have hit Earth in the past?

Moon. Because of virtually no erosion, you can estimate a frequency of impacts occurring at about our orbit. Erosion on Earth quickly erases traces of most impact craters, so we can't find them all.


How do you know asteroids have hit the earth?

The evidence that asteroids have collided with earth before, depends on the surface. The way you can find this if there is unusual shapes in the ground( e.g. really deep ditch, that is too big for a human too dig).
