Igneous rock forms from molten rock in the form of magma or lava. Because of the importance of silica content, it has become common practice to use this feature of igneous rocks as a basis for subdividing them into the following groups: silicic or felsic (or acid, an old and discredited but unfortunately entrenched term), rocks having more than 66 percent silica; intermediate, rocks with 55 to 66 percent silica; and subsilicic, rocks containing less than 55 percent silica. Igneous rocks constitute one of the three principal classes of rocks, the others being metamorphic and sedimentary. Igneous Rocks introduces students to this group of rocks.
