Web continental crust is broadly granitic in composition and, with a density of about 2.7 grams per cubic cm, is somewhat lighter than oceanic crust, which is basaltic (i.e., richer in iron and magnesium than granite) in composition and has a density of about 2.9 to 3 grams per cubic cm. The continental crust varies in thickness between 6 and 43 miles (25 and 70km). Web composed mostly of granite, the continental crust is the layer of igneous, sedimentary, and metamorphic rocks which forms the continents and the areas of shallow seabed close to their shores,. The continental crust varies in thickness between 6 and 43 miles (25 and 70km). The average density of continental crust is about 2.83 g/cm 3 (0.102 lb/cu in), less dense than the ultramafic material that makes up the mantle, which has a density of around 3.3 g/cm 3 (0.12 lb/cu in). Web what is the continental crust? Because continental crust is rarely destroyed and recycled in the process of subduction, some sections of continental crust are nearly as old as the earth itself. The continental crust is mainly composed of granite. The planet's continents as well as continental shelves are made of the continental crust, which is the outer part of the lithosphere and forms at plate boundaries where the oceans and mainland tectonic bands subduct beneath one another. It is made up of a variety of rock types, all of which are lighter than the denser, more tightly packed rocks found in the oceanic crust.

Some of the rocks in the. The continental crust varies in thickness between 6 and 43 miles (25 and 70km). Continental crust does not subduct. Because continental crust is rarely destroyed and recycled in the process of subduction, some sections of continental crust are nearly as old as the earth itself. Web the continental crust is the layer of igneous, sedimentary and metamorphic rocks. The continental crust varies in thickness between 6 and 43 miles (25 and 70km). Web continental crust is broadly granitic in composition and, with a density of about 2.7 grams per cubic cm, is somewhat lighter than oceanic crust, which is basaltic (i.e., richer in iron and magnesium than granite) in composition and has a density of about 2.9 to 3 grams per cubic cm. Some of the rocks in the. Extraterrestrial crust our solar system’s other terrestrial planets (mercury, venus, and mars) and even our own moon have crusts. The continental crust is mainly composed of granite. Web the continental crust consists of various layers, with a bulk composition that is intermediate (sio 2 wt% = 60.6).
