the oceanic crust is thinner, generally5-8 killometers thick, and is made of basalt, but the continental crust is an average of 30 km and is made of granite
Oceanic and Continental crusts are alike because they both shift and move and grow. They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of...
Thickness - continental = much thicker
Density - oceanic crust is denser than continental, which is why the oceanic crust subducts under the continental at destructive plates boundaries.
There are two main regions of the crust. The top layer (continental crust) riches in silica and aluminium, the lower layer (oceanic crust) riches in silica and magnesium. Both of these crust are the...
