Igneous rocks, sedimentary rocks, and metamorphic rocks are the three primary kinds of rocks. Rocks are formed when the small grains of various minerals are crushed by the pressure they are subjected to. Igneous rocks are classified according to mode of occurrence, texture, mineralogy, chemical composition, and the geometry of the igneous body. The classification of the many types of igneous rocks can provide important information about the conditions under which they formed. Two important variables used for the classification of igneous rocks are particle size, which la…
