WebThe lithosphere is divided into tectonic plates. There are seven major tectonic plates - the African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American tectonic plates. Tectonic plates are able to float on the mantle due to the composition of the rocks within the plates that make them less dense than the mantle. WebAn important consequence of the difference in density is that if tectonic plates happen to bring ocean crust and continental crust into collision, the plate with ocean crust will be forced down into the mantle beneath the plate with continental crust. ... Rocks higher in the mantle are typically composed of peridotite, a rock dominated by the ...
