1). A crater is a circular depression on the surface of a planet. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the ecenter of a crater often forms a [crater lake]? and in craters formed by meteorites, a central island is usually a prominent feature in the lake. |

Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a [crater lake]? often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. |
