A new layer of molten rock under the Earth has scientists ... the Earth’s upper mantle. Details about this area of the Earth have long been a mystery. However, the discovery of this new layer ...

(b) Compression causes the metals in the molten zone to solidify and sink. (c) Then thermal convection mixes and redistributes the metal-impregnated mantle components over long geologic time frames.

The mantle is made up of different layers. The upper mantle is hard but below that is semi-molten rock called magma. Crust The crust is the outer layer of the Earth on which we live. It is the ...

This mantle is constantly in motion due to the heat from the deeper part of the earth. One result is that the heated semi-solid rock (molten rock) can be forced up from the mantle and erupt ...
