An impact crater is an approximately circular depression in the surface of a planet, moon or other solid body in the Solar System, formed by the hypervelocity impact of a smaller body with the surface. In contrast to volcanic craters, which result from explosion or internal collapse,[1] impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain.[2] Impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is perhaps the best-known example of a small impact crater on the Earth.
Researchers have found evidence that the crater in case was formed when the ground was slammed by a massive meteorite, millions of years ago. Prince Albert crater Measuring about 25 kilometers across, Prince Albert crater was named after the peninsula in which it was discovered. Researchers never were really sure when it was formed, the [...]
