Cryovolcanism is the process of volcanic activity on icy bodies such as moons and dwarf planets in the outer solar system, where water, ammonia, methane, and other volatile substances serve as the eruptive material instead of molten rock. These cryovolcanoes are thought to erupt due to the presence of subsurface reservoirs of liquid water or other volatiles that can become pressurized and erupt onto the surface, forming icy features such as plumes, domes, and lava flows. This process is believed to play a significant role in shaping the surfaces of icy bodies and may also be responsible for the presence of organic compounds and possible habitats for microbial life in these extreme environments. Cryovolcanism has been observed on moons such as Enceladus, Europa, and Triton, providing valuable insights into the geology and potential habitability of these distant worlds.
