Magma often collects in magma chambers that may feed a volcano or solidify underground to form an intrusion. Magma is capable of intrusion into adjacent rocks (forming igneous dikes and sills), extrusion onto the surface as lava, and explosive ejection as tephra to form pyroclastic rock.emperatures of most magmas are in the range 700 Â°C to 1300 Â°C (or 1300 Â°F to 2400 Â°F), but very rare carbonatite magmas may be as cool as 600 Â°C, and komatiite magmas may have been as hot as 1600 Â°C. Most magmas are silicate mixtures.
This material solidifies extremely fast because it is exposed to the cooler temperatures found at the Earth's surface while it is in a molten state, at temperatures of 800 to 1200 degrees Celsius while the temperature on the Earth's surface is a mere 20 or so degrees Celsius.
