If there is liquid in volcanic rocks, it would most likely be water.
Geothermal Water
An extrusive rock is a rock that has been deposited at the earths surface as a liquid/fluid, coming to the surface form a depth through a fissure in the earth as a liquid/fluid. The most common type of liquid rock is a magma and magmas erupting at the surface are called "volcanoes" and thus the rocks are called "volcanic" rocks. However there are also volcanoes to be found that have nothing to do with molten rock magmas. These are called "Mud" volcanoes and they are caused by de-watering processes in rocks. The muds brought to the surface are also technically extrusive and these are NOT volcanic rocks.
Yes. Volcanic rocks are extrusive igneous rocks.
normally found in a volcanic eruption zone where carbon is present
Basaltic
Pigeonite is normally found in igneous rocks such as dacite and andesite which are both extrusive igneous rocks. Pigeonite is found in meteorites such as eucrite and achondrite. In volcanic rocks it is found as phenocrysts and as crystals in meteorites.
Igneous rocks and volcanic minerals are usually found near a volcano.
No. Volcanic rocks are made of the same materials that other rocks are.
No. Only extrusive igneous rocks are volcanic.
No. Volcanic rocks are extrusive. Intrusive rocks are sometimes called plutonic.
Volcanic rocks are classified as extrusive igneous rocks, forming from the solidification of lava.
Oil is the liquid energy that is found between layers of rocks.
