Question

A rock is a solid, inorganic naturally-formed substance without a particular atomic structure or chemical composition. Each rock consists of several different minerals which are mixed up inside the rock.

Common felsic minerals are quartz, feldspar, and the feldspathoids. These types of rocks would be granite, and rhyolite. Common mafic minerals are olivine, pyroxene, amphibole, and biotite. These type of rocks would be basalt, disbase, and gabbro. Intermediate rocks are know as andesite. This type of rock is Diorite. Common minerals found in Ultramafic are olivine and pyroxene. This type of rock woulf be periodtite.

Felsic rocks can be found near volcanic activity, intermediate rocks are along continental margins, mafic rocks are found on the underside of the oceanic crust, and ultramafic rocks are found in North Cascades.

Intrusive are course grained and extrusive are fine grained.
