Continental crust is the layer of igneous, metamorphic, and sedimentary rocks that forms the geological continents and the areas of shallow seabed close...

including both dry land and continental shelves". The geological continents correspond to seven large areas of continental crust that are found on the tectonic...

the crust is about 15 - 20 km (9 - 12 mi). Because both the continental and oceanic crust are less dense than the mantle below, both types of crust "float"...

lithosphere. Oceanic crust is primarily composed of mafic rocks, or sima, which is rich in iron and magnesium. It is thinner than continental crust, or sial, generally...

Continental crustal fragments, partly synonymous with microcontinents, are pieces of continents that have broken off from main continental masses to form...

kinds of crust of different composition: continental crust and oceanic crust, both floating above a much deeper "plastic" mantle. Continental crust is inherently...

A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean...

(different bits of continental crust), separated across a tract of ocean (and oceanic crust), approach each other, while the oceanic crust is slowly consumed...

include both structural deformation of existing continental crust and the creation of new continental crust through volcanism. Magma rising in the orogen...

terrestrial planets have fairly uniform crusts. Earth, however, has two distinct types: continental crust and oceanic crust. These two types have different chemical...
