Editing Volcanism (section)

==Types==
=== Silicate volcanism ===

Silicate volcanism occurs where silicate materials are erupted. Silicate lava flows, like those found on Earth, solidify at about 1000 degrees Celsius.<ref name=":6" />

=== Mud volcanoes ===

This pressure can be caused by the weight of overlying sediments over the fluid which pushes down on the fluid, preventing it from escaping, by fluid being trapped in the sediment, migrating from deeper sediment into other sediment or being made from chemical reactions in the sediment. They often erupt quietly, but sometimes they erupt flammable gases such as methane.<ref name=":5">{{Cite web |last=Hudec |first=Michael R. |date=December 20, 2022 |title=What are mud volcanoes? |url=https://theconversation.com/what-are-mud-volcanoes-173198 |website=The Conversation |access-date=2024-03-17}}</ref>

=== Cryovolcanism ===
Cryovolcanism is the eruption of [[Volatility (chemistry)|volatiles]] into an environment below their freezing point. The processes behind it are different to silicate volcanism because the cryomagma (which is usually water-based) is normally denser than its surroundings, meaning it cannot rise by its own buoyancy.<ref>{{Cite web |last=Klemetti |first=Erik |date=25 September 2023 |title=Cryovolcanism's Song of Ice and Fire |url=https://eos.org/features/cryovolcanisms-song-of-ice-and-fire |publisher=[[American Geophysical Union]] |work=[[Eos (magazine)|Eos]] |access-date=2024-03-17}}</ref><ref name=":3" />

=== Sulfur ===
Sulfur lavas have a different behaviour to silicate ones. First, sulfur has a low melting point of about 120 degrees Celsius. Also, after cooling down to about 175 degrees Celsius the lava rapidly loses viscosity, unlike silicate lavas like those found on Earth.<ref name=":6">{{Cite web |title=Sulphur vs. Silicate |url=https://volcano.oregonstate.edu/sulfur-vs-silicate |website=Volcano World|date=4 January 2012 }}</ref>
