Continental crust - Wikipedia

Continental crust is the layer of igneous, metamorphic, and sedimentary rocks that forms the geological continents and the areas of shallow seabed close to their shores, known as continental shelves.

In addition, the continental crust is much thicker than the oceanic crust. The continental crust is older than the oceanic crust. This fact can be easily explained by the recycling process of the oceanic crust ... WebThe density of the layer is higher than the crust and varies from 3.3 – 5.4g/cm3. The uppermost solid part of the mantle and the entire crust constitute the Lithosphere . The asthenosphere (in between 80-200km) is a highly viscous, mechanically weak and ductile, deforming region of the upper mantle which lies just below the lithosphere. lego super mario bowsers luftschiff

Characteristics of oceanic crust in terms of density

WebWhile the continental crust is 30–70 km thick, the oceanic crustal thickness is 6–12 km. The oceanic crust is also denser (2.8–3.0 g/cm 3) than the continental crust (2.6–2.7 g/cm 3 ).

Density of the crust

WebThe crust, with an average density of around 2.6 grams per cubic centimetre (g/cm3), is less dense than the mantle (average density of approximately 3.4 g/cm3 near the surface, but more than that at depth), and so it is floating on the “plastic” mantle.

A slice of the planet that contains a mountain has the same mass as a slice that contains flat land, because the crust that makes the mountain is less dense than the crust that makes flat land. In all points of the planet, the bottom of the crust floats evenly on the mantle.
