Igneous rocks that form inside the earth from slowly cooling magma. Web extrusive (or, volcanic) igneous rocks are formed on the earth’s surface as the result of volcanic activity. Most extrusive (volcanic) rocks have small crystals. Specimens are black in color and weather to dark green or brown. The molten rock erupts or flows above. Web extrusive rock refers to the mode of igneous volcanic rock formation in which hot magma from inside the earth flows out (extrudes) onto the surface as lava or explodes violently.
