Magma chamber

A magma chamber is a large pool of liquid 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 buoyant forces on the magma that tend to drive it upwards.[1]
If the magma finds a path to the surface, then the result may be a volcanic eruption. Many volcanoes sit over magma chambers.[2] These chambers are hard to detect if they are deep within the Earth. Most of those known are close to the surface.[3]
