Rocks: Igneous, Sedimentary & Metamorphic .

Rocks are an aggregate of one or more minerals held together by chemical bonds. Feldspar and quartz are the most common minerals found in rocks. The scientific study of rocks is called petrology. Based on the mode of formation three major groups of rocks are defined: igneous, sedimentary, and metamorphic. Igneous Rocks — solidified from magma and lava.
