A crater is a large, bowl-shaped depression in the ground, often formed by volcanic activity or the impact of a meteorite. When a volcano erupts, it can create a crater at its summit, where magma escapes. Similarly, when a meteorite strikes the Earth, it leaves behind a crater, which can vary in size depending on the force of the impact. Crater formations can be found on various celestial bodies, including the Moon and Mars. For example, the famous Tycho Crater on the Moon is easily visible from Earth and showcases the effects of a significant impact. Craters provide valuable information about the history of our planet and the solar system.
