Questions about a depression on the surface of solid celestrial ojects, use also when asking about maar or caldera.
A crater may refer to different pit-like landforms like
- Impact craters which are formed when two celestial bodies impacting each other.
- Explosion craters which are produced by an explosion near or below the surface
- Pit craters form through sinking of the surface and not as a vent for lava
- Volcanic craters are caused by volcanic activity, e.g. a caldera or a maar
