Rock - In*geology, a**is a naturally occurring solidaggregate*of one or more*minerals*or*mineraloids. For example, the common rock*granite*is a combination of the*quartz,*feldspar*and*biotiteminerals. The Earth's outer solid layer, thelithosphere, is made of rock.

Rocks have been used by mankind throughout history. From the*Stone Age*rocks have been used for tools. The minerals and metals we find in rocks have been essential to human civilization.[1]

Three major groups of rocks are defined:*igneous,sedimentary, and*metamorphic. The scientific study of rocks is called*petrology, which is an essential component of geology.
