<P> The interior of Earth , similar to the other terrestrial planets , is divided into layers of different composition . The mantle is a layer between the crust and the outer core . Earth 's mantle is a silicate rocky shell with an average thickness of 2,886 kilometres ( 1,793 mi ) . The mantle makes up about 84 % of Earth 's volume . It is predominantly solid but in geological time it behaves as a very viscous fluid . The mantle encloses the hot core rich in iron and nickel , which makes up about 15 % of Earth 's volume . Past episodes of melting and volcanism at the shallower levels of the mantle have produced a thin crust of crystallized melt products near the surface . Information about the structure and composition of the mantle has been obtained from geophysical investigation and from direct geoscientific analyses of Earth mantle - derived xenoliths and mantle that has been exposed by mid-oceanic ridge spreading . </P>
