molten rock in the earth's crust
The molten matter within the earth, the source of the material of lava flows, dikes of eruptive rocks, etc.
A basic algebraic structure consisting of a set equipped with a single binary operation.
Origin: From μάγμα.
any crude mixture of mineral or organic matters in the state of a thin paste
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
a salve or confection of thick consistency
the molten matter within the earth, the source of the material of lava flows, dikes of eruptive rocks, etc
the glassy base of an eruptive rock
the amorphous or homogenous matrix or ground mass, as distinguished from well-defined crystals; as, the magma of porphyry
Origin: [L., fr. Gr. , fr. to squeeze, knead.]
Magma is a mixture of molten or semi-molten rock, volatiles and solids that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets. Besides molten rock, magma may also contain suspended crystals, dissolved gas and sometimes gas bubbles. Magma often collects in magma chambers that may feed a volcano or turn into a pluton. Magma is capable of intrusion into adjacent rocks, extrusion onto the surface as lava, and explosive ejection as tephra to form pyroclastic rock. Magma is a complex high-temperature fluid substance. Temperatures of most magmas are in the range 700 °C to 1300 °C, but very rare carbonatite melts may be as cool as 600 °C, and komatiite melts may have been as hot as 1600 °C. Most are silicate mixtures. Environments of magma formation and compositions are commonly correlated. Environments include subduction zones, continental rift zones, mid-ocean ridges and hot spots. Despite being found in such widespread locales, the bulk of the Earth's crust and mantle is not molten. Rather, most of the Earth takes the form of a rheid, a form of solid that can move or deform under pressure. Magma, as liquid, preferentially forms in high temperature, low pressure environments within several kilometers of the Earth's surface.

Sample Sentences & Example Usage
It’s difficult to tell how big an eruption might be. Knowing how much eruptible magma is down there may tell us.
If hot water or magma becomes involved, it could explode at a deeper level, and there would probably be very little warning, things are now taking place at a shallow level and probably it won't go that far. But you can't say when that might change.
As far as we can determine, none of these places currently house the type of melt-rich, giant magma body needed to produce a super-eruption, however, they are places where super-eruptions have happened in the past so are more likely to happen in the future.
The magma chamber is likely imparting its own stresses on the crust around and above it, as the system slowly recharges. The stress drives fluids through cracks, producing the small quakes. The current pattern of seismicity is similar to swarms seen at Mount St. Helens in 2013 and 2014; recharge swarms in the 1990s had much higher earthquake rates and energy release.
We often say"Forgive and Forget." That's the correct sequence IMHO. If you want to forget someone or some unpleasant event, you must first forgive. Forgiveness is the precursor to Forgetting. If you don't forgive, you'll never forget, and that someone or that unpleasant event will stay with you, carved inside your heart and deep in your mind. Like a magma chamber of a volcano, you will then embody the hot burning lava of hate and volcanic ashes of bad memories. So to move on with life, you ought to learn to forgive, first and foremost, even the worst people round you. The stream of life would then flow smoothly and seamlessly - onwards and upwards.
