Molten or partially molten rock at temperatures ranging from 700 deg C to 1600 deg C (1260 deg F to 2880 deg F) Some magma bodies are believed to exist at drillable depths within the earth's crust, although practical technologies for harnessing magma energy have not been developed If ever utilized, magma represents a potentially enormous resource
The amorphous or homogenous matrix or ground mass, as distinguished from well-defined crystals; as, the magma of porphyry
molten rock beneath the surface of the earth (molten rock at the surface is called "lava")
naturally occurring molten rock, generated within the earth's crust or in the upper mantle and capable of intruding (being thrust into) the earth's crust or penetrating it and erupting through volcanic craters
Molten rock containing liquids, crystals, and dissolved gases that forms within the upper part of the Earth's mantle and crust When erupted onto the Earth's surface, it is called lava
Molten rock, formed within the inner parts of the Earth, which crystallises to form an igneous rock
Molten rock beneath the earth's surface Magma is called "lava" when it erupts from a volcano
the molten rock material under the earth's crust, from which igneous rock is formed by cooling
Naturally occurring molten rock material, generated within the earth and capable of being intruded into other rocks or extruded onto the surface of the earth
Molten rock within the crust of a planet that is capable of intrusion into adjacent crustal rocks or extrusion onto the surface Igneous rocks are derived from magma through solidification and related processes or through eruption of the magma at the surface
hot melted rock below the surface of the Earth (from massein ). Molten or partially molten rock from which igneous rocks form, usually consisting of silicate liquid. Magma migrates either at depth or to the Earth's surface, where it is ejected as lava. The interactions of several physical properties, including chemical composition, viscosity, content of dissolved gases, and temperature, determine the characteristics of magma. Numerous events that can occur during crystallization influence the resulting rock: separation of early crystals from liquid prevents reaction between them; magma can cool too rapidly for reaction to occur; and loss of volatiles may remove some components from the magma
Naturally occurring mobile rock material, generated within the Earth and capable of intrusion and extrusion, from which igneous rocks are thought to have been derived through solidification and related processes It may or may not contain suspended solids (such as crystals and rock fragments) and/or gas phases
A thick residuum obtained from certain substances after the fluid parts are expressed from them; the grounds which remain after treating a substance with any menstruum, as water or alcohol
