Ice volcanoes which are commonly known as cryovolcanoes are the types of volcanoes that occur in the solar system’s frozen regions. A regular volcano is made up of molten rocks or lava, whereas the ice volcano erupts volatiles compounds such as water, ammonia, methane, nitrogen that is accompanied by gas driven fragments, this process is called cryomagma. After then eruption had occurred, cryomagma forms in a solid form when it get exposed to a very low temperature surface. The energy required to form cryovolcanoes usually comes from tidal friction. Tidal stimulation is an effect of the tidal forces. The tidal force is the difference in the strength of gravity between two points on body. Tidal friction is the effect of tidal wave slowing down the rotation. Cryomagma may escape from the surface of an ice because of the weak gravity. Heat that builds up in the core of moons as they bend and distort in the gravity field of the massive gas giants they orbit. . During an eruption, lava melt resulting from the lower temperature the snow -covered volcano layer. Water and lava cooled quickly, productive forms of lava similar to those of underwater volcanoes. When separated lava and rolled down the slopes of the volcano and rocks coherent and rocks tightly knit to the girl child volcanic glass is formed, has been stepping up the melted water from the bottom of the ice sheet, as happened in Iceland in 1996, when the eruption of a volcano lake which thaw about 3 km cube of ice, leading to a great flood in the lake ice. And characterized by volcanoes under the ice forms a unique and unusual ; it is flat- top and sides of steep supported Ocean ice and water soluble pressure from collapse . The volcano under the glacier, also known as ice volcano, is a form of volcanoes caused by the eruption under the ice or eruption is happening under the surface of a glacier or ice cap to melt component because of the rising lava lake. If the start of the volcano is to melt in another matter entirely through the ice layer, the horizontal floating lava deposited and almost take the form of a flat summit of the volcano. In spite of that, if large amounts of erupted lava then about quasi- antenna may be assumed that the form of the volcano after it traditionally. It is also suspected that some moons may have translucent layers of ice that permit light in to heat material beneath it, but have an insulating property that seals in heat and creates a greenhouse effect. Some moons have layers of ice which allows light to go through to heat the material under it. Because it has an insulating capacity, it seals down the heat, which creates pressure in the interior part. In time, it will be strong enough to escape the inner surface and form cryovolcano. This creates pressurized gases in the interior that will escape if there is a route to the surface, thus creating a cryovolcano. The friction on the rock will cause it to heat. In turn, this friction over a long period of time would cause the surrounding ices to melt. The friction on the rock will cause it to heat. In turn, this friction over a long period of time would cause the surrounding ices to melt. In the case of Enceladus which has no surface atmosphere the volatiles of liquid would spew out in huge plumes and vent into space. However on Titan, which has an atmosphere, the spewed material stays contained within the moon system. Although an ice volcano has not been witnessed directly, astronomers have pointed to evidence in Titan’s features that are similar to earth’s volcanoes. The gravity of the plant the orbit is the source of the energy that causes cryovolcano. We can see Cryovolcanoes most in the solar system’s frozen places and it is very rare to find it in earth. Saturn’s largest moon Titan is an example of where we can find Cryovolcanoes. Where such volcanoes may spew liquid from an ocean hidden in the moon’s interior. Ice volcanoes were first observed on Neptune’s moon Triton in 1989, on November 27, 2005 Cassini photographed geysers on the south pole of Enceladus.

The size of the Ice volcano ranges from less than one meter to greater than 8 meters in height, measured by the base of the peak. The largest cones happened on the areas, which has high energy waves. There are two shapes of cones that has been observed (shield volcano and stratovolcano) a volcano built up of alternate layers: domed volcano with gently sloping sides, characteristic of the eruption of fluid and two forms of symmetry unbreached and breached. Breached means make a gap in and break through. , the formation of cones can be related to symmetry. Cones forming on the leading edge of the ice shelf are breached in the lake ward direction. Occurring landward from the shelf’s edge form unbreached cones

Due to the Gaseous envelope of the moon such as the organic carbon Scientists believe the existence of ocean water liquid such as mixed with ammonia terrestrial ocean located below the ice of the moon surface, and the small number of nozzles meteorites on the surface indicates that the moon is a recent and very active and dynamic, supports this belief and the presence of clouds and rain of liquid methane-like water circulation process on the ground any when the water evaporates from the oceans and seas to atmospheric ground in the form of clouds then condenses and falls as rain. These physical manifestations in the gaseous envelope of the moon “Titan” ice surface, which covers liquid oceans strongly supports the “ice volcanoes” theory on the lunar surface, in addition to the change in gloss moon and reflectivity Albedo any proportion reflection incoming sunlight on its surface, as well as provide the gaseous envelope of the moon permanently methane. Scientists have also conducted laboratory experiments, where they were placed in a tube Ethan liquid cooled to the point of 179 ° C (as is the temperature of the moon) and added his substance benzene. As the benzene dissolves very quickly in liquid ethane, so scientists concluded that lakes and Sailor Moon is rich in hydrocarbons.
