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.
Which statement best describes the formation of an intrusive igneous rock? here are the choices: A.Magma solidifies slowly, resulting in a coarse-grained texture. B.Magma solidifies slowly, resulting in a fine-grained texture. C.Magma solidifies rapidly, resulting in a glassy texture. D.Magma solidifies rapidly, resulting in a clastic texture.
