Cryovolcanoes

Cryovolcanoes are a type of volcano that erupt instead of molten rock, releasing instead volatile substances like water, ammonia, or methane. Found on icy bodies such as moons and some dwarf planets, these eruptions occur when internal heat causes these substances to vaporize and escape through surface openings. Unlike Earth's volcanoes that erupt lava, cryovolcanoes spew icy slurries or gases, shaping surface features. They provide clues about the composition and potential subsurface oceans of these worlds, offering insights into their geology, potential habitability, and the cycles of their icy environments.
