WebThe mantle is made up of molten rock called magma. This magma circulates in currents determined by the cooling and sinking of heavier minerals and the heating and rising of lighter minerals. All but the very uppermost portion of the mantle is part of the asthenosphere, which refers to the liquid zone of the inner Earth. Web7 apr. 2024 · One such part is the lithosphere. As per the lithosphere definition, it is the outer layer that resides on the top of the mantle and underneath the crust. It is the rigid and rocky part of the earth’s inner sections that goes up to 100 km beneath the earth’s crust. This layer of earth lies on the asthenosphere.
