How was the Beaverhead crater formed? What caused the Wetumpka impact crater to form? What is the Chicxulub crater made of? How is the shape of an impact crater formed? What forms inside the crater of a large volcano? What caused the Vredefort crater?
1. The largest impact crater on Earth, the Vredefort crater in South Africa, is 99 miles (160 km) wide and was likely created about 2 billion years ago, according to NASA's Earth Observatory. The crater has largely eroded, but based on what's left of the rim, scientists have estimated...
not the least of which is trying to pinpoint the Moon's age.We could do this, in theory, by studying an enormous impact crater known as the South Pole–Aitken Basin.Ah, it's located in the Moon's south polar region.But, since it's on the far side of the Moon, it can be seen...
And it’s conceivable that a very large strike from an impactor might throw up some fairly large chunks, ones that’re larger than some of the smaller direct strikes. So we can’t use size to determine if a crater is the result of a primary impact or a secondary one. ...

Geologists originally believed that Eye of the Sahara was an impact crater, created when an object from space slammed into the surface. However, lengthy studies of the rocks inside the structure show that its origins are entirely Earth-based. ...
