Cryovolcanism is a geological phenomenon distinct from the more familiar volcanism involving molten rock. Instead of lava, cryovolcanism erupts volatile substances such as water, ammonia, or methane. These substances are typically in a liquid or slushy state at the temperatures found on the surfaces of certain celestial bodies. When these volatiles are expelled from the interior of a planet or moon, they can freeze rapidly upon contact with the extremely cold external environment, forming ice. This process is often referred to as cryovolcanism or ice volcanism.

The presence of cryovolcanism suggests that a celestial body has an internal heat source sufficient to keep these volatile substances in a liquid state beneath its surface, or that there are processes generating heat within its interior. Such internal heat can originate from tidal forces exerted by a larger orbiting body, radiogenic decay, or residual heat from formation. Observations of cryovolcanic features are crucial for understanding the internal structure, thermal history, and potential habitability of icy moons and dwarf planets within our solar system and beyond. Features like geysers and icy plains can be indicative of ongoing or past cryovolcanic activity.
