<span>Rocks can best be identified by their mineral content. This is
because rocks are composed of one or multiple numbers of minerals. Quartz,
calcite, feldspars, and micas are examples of minerals that make rock formations
possible.
Rocks are the basic component of the Earth's crust. Mountains, hills, and
volcanoes are examples of rock formations that occur through time on Earth. One
can find rocks all over the Earth and most are usually under the soil. Rocks
can be further classified as igneous, sedimentary, or metamorphic rocks.</span>
