Meteorite Crater Landscape
A meteorite crater is a circular depression formed by the impact of a meteorite on the surface of a planet, satellite, asteroid or other celestial body. A small mound is often located in the centre of the crater. The meteorite craters on Earth are often filled with water to form impact lakes, and there is always an island in the centre. Larger craters are also known as circular mountain rims. As a result of erosion and sedimentation, ancient meteorite craters can disappear and are not easy to identify. Typical examples are the craters on the Canadian Shield.
