What is Magma chamber?
[[File:Vulcanian Eruption-numbers.svg|thumb|11 – magma chamber]] A '''magma chamber''' is a large pool of [[liquid]] [[Rock (geology)|rock]] under the surface of the [[Earth]]. The molten rock, or [[magma]], in such a chamber is less dense than the surrounding rock. This produces [[Buoyancy|buoyant forces]] on the magma that tend to drive it upwards.<ref>{{cite book |last1=Philpotts |first1=Anthony R. |last2=Ague |first2=Jay J. |title=Principles of igneous and metamorphic petrology |date=2009 |publisher=Cambridge University Press |location=Cambridge, UK |isbn=9780521880060 |pages=28–32 |edition=2nd}}</ref> If the magma finds a path to the surface, then the result may be a [[volcanic eruption]]. Many [[volcano]]es sit over magma chambers.<ref>{{Cite web|title=Forensic Probe of Bali's Great Volcano|url=https://eos.org/science-updates/forensic-probe-of-balis-great-volcano|access-date=2020-11-25|website=Eos|date=12 February 2019 |language=en-US}}</ref> These chambers are hard to detect if they are deep within the Earth.
