A magma-filled cavity within the lithosphere.

the chamber in which magma is stored before erupting pillow lava: lava that cools in water and resumes a fluffy, pillowy shape.

A body of molten rock at depth beneath the Earth's surface.

A full or emptied magma reservoir in the shallow portion of the lithosphere.

A reservoir of magma in the shallow part of the lithosphere from which volcanic materials are derived; the magma has ascended into the crust from an unknown source.

a reservoir of magma in the crust from which volcanic material is derived.

a reservoir of molten rock that is the source of lava in a volcanic eruption

A chamber(cavity or reservoir) in the lithosphere where rising magma is "collected" and halts for varying lengths of time.

a reservoir of magma beneath Earth's surface.

Reservoir of magma underneath the volcano.

A space beneath the surface of the earth surrounded by solid rock and containing magma.

A magma reservoir in the shallow part of the lithosphere.

The subterranean cavity containing the gas-rich liquid magma which feeds a volcano.

A body of molten rock and solid crystal mush beneath the Earth's surface. When this chamber cools and solidifies, it is called a pluton.

A three dimensional mass of molten rock (magma) within the crust often below a volcano. During eruption, the magma chamber may partially empty leaving a void.

a cavity beneath a volcano where magma collects

A large body of magma below the volcano that rises up through the column and feeds the volcano.

A space in the Earth's crust or mantle which contains a volume of molten rock, ie magma.

A large reservoir in the earthâ€(tm)s crust occupied by a body of magma.

A magma chamber is an underground cavity filled with gas-rich magma (molten rock). This magma erupts through volcanoes.

A magma chamber is a large underground pool of molten rock lying under the surface of the earth. The molten rock in such a chamber is under great pressure, and given enough time and pressure can gradually fracture the rock around it creating outlets for the magma. If it finds a way to the surface, then the result will be a volcanic eruption; consequently many volcanoes are situated over magma chambers.
