Splet01. jan. 2014 · In general, the continental crust has lower seismic velocities and consists of lighter material than the underlying mantle; V P is smaller than 7.8 km/s, V S smaller than 4.3 km/s, and ρ below 3.1 g/cm 3. Crustal thickness is between 20 km (shelves) and more than 70 km (some orogens) (Mooney et al., 2005 ).

Splet05. apr. 2004 · The low density of continental crust causes it to “float” high atop the viscous mantle, forming dry land. Conversely, dense oceanic crust does not “float” as high—forming lower-lying ocean basins. As oceanic crust cools, it becomes denser and ultimately sinks back into the mantle under its own weight after about 200 million years.
