The crust is composed of many different types of rocks that fall into three main categories.
Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar.
Oceanic crust the outermost layer of earth s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges which occur at divergent plate boundaries.
It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.
It makes up about 2 of the earth s total mass.
