The Continental Crust Is Apex. 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 the continental crust is the layer of igneous, sedimentary and metamorphic rocks.

Some of the rocks in the. 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. Oceanic crust subducts under a less dense crust whether it's oceanic or continental. Continental crust does not subduct. Web continental crust is granitic. Web the continental crust is the layer of igneous, sedimentary and metamorphic rocks. European crust granites of various sorts make up the majority of the crust. 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,. 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. Extraterrestrial crust our solar system’s other terrestrial planets (mercury, venus, and mars) and even our own moon have crusts.
European crust granites of various sorts make up the majority of the crust. 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,. 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 the continental crust consists of various layers, with a bulk composition that is intermediate (sio 2 wt% = 60.6). Oceanic crust subducts under a less dense crust whether it's oceanic or continental. Web continental crust is almost always much older than oceanic crust. 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. 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.
