What do you mean by CryoVolcano?

A cryovolcano (colloquially known as an ice volcano) erupts slurries of volatile compounds such as water or methane instead of lava. These substances are usually liquids and form plumes, but can also be in vapour form. After eruption, cryomagma condenses to a solid form when exposed to the very low surrounding temperature. Cryovolcanoes form on icy moons, and possibly on other low-temperature astronomical objects (e.g., Kuiper belt objects).
The energy required to melt ices and produce cryovolcanoes usually comes from tidal friction. It has also been suggested that translucent deposits of frozen materials could create a sub-surface greenhouse effect that would accumulate the required heat.
Ice volcanoes were first observed on Neptune's moon Triton during the Voyager 2 flyby in 1989.
On November 27, 2005 Cassini photographed geysers on the south pole of Enceladus.

Indirect evidence of cryovolcanic activity was later observed on several other icy moons of our Solar System, including Europa, Titan, Ganymede, and Miranda. Cassini has observed several features thought to be cryovolcanoes on Titan. Such volcanism is now believed to be a significant source of the methane found in Titan's atmosphere.
In 2007, observations by the Gemini Observatory showing patches of ammonia hydrates and water crystals on the surface of Pluto's moon Charon suggested the presence of active cryovolcanoes/cryo-geysers

  12. A cryovolcano is an icy volcano found on icy bodies, especially moons, in the outer solar system. Cryovolcanoes have been observed directly on Neptune's moon Triton, during a Voyager II fly-by in 1989, and on Saturn's moon Enceladus, by the Cassini probe on 27 November 2005. Indirect evidence of cryovolcanism has been found on several other moons and bodies, including Europa, Titan, Ganymede, Miranda, and the trans-Neptunian object Quaoar.

    Instead of erupting molten rock, as in a conventional volcano, cryovolcanoes erupt volatiles (low boiling point elements or compounds), like water, ammonia, carbon dioxide, nitrogen, or methane, accompanied by gas-driven solid fragments. This is called cryomagma. A cryovolcano produces plumes that may be a hundred or more degrees hotter than the frozen surface matter. Exposed to the cold and vacuum of space, the plumes quickly solidify, becoming airborne dust. As the gravity is weak on many ice moons, the plume may completely escape the moon's gravity well, go into an orbit, or crash back down on the surface in another area.

  17. Cryovolcanos ejects some gases like methane, wates crystals or ammonium hydrates. Traces of these materials can help in finding cryovolcanos on other planets

  19. cryovolcanos are some of the gases like methane which can be used in space planets and the characteristics of this is it exposed at very low tempreature
