Why oceanic crust is more dense than continental crust?

Oceanic crust is denser because it generally melts to a higher fraction than continental crust. When rocks melt some minerals melt before others.Click to see full answer. Regarding this, which portion of Earth’s crust is more dense oceanic or continental?Oceanic crust is thinner and denser than continental crust. Oceanic crust is darker in color and denser (more mafic). Continental crust is lighter in color and density (more felsic). Earth’s crust is very thin relative to Earth’s radius.Also, in what ways does oceanic crust differ from continental crust? Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition. Like continental crust, however, oceanic crust is destroyed in subduction zones. The lavas are generally of two types: pillow lavas and sheet flows. In this manner, why are oceanic plates denser than Continental? Oceanic and Continental Plates The oceanic plate is denser and sinks due to its lower buoyancy. It is sucked into the asthenosphere and is melted deeper into the Earth, called a subduction zone. The continental plate is less dense and floats over the top of it since it is more buoyant.What are the two types of crust? Earth’s Crust There are two different types of crust: thin oceanic crust that underlies the ocean basins, and thicker continental crust that underlies the continents. These two different types of crust are made up of different types of rock.
