Tectonic Plates are floating on the semi-molten Mantle. Currents in the molten layer, eruptions of new lava round the edges, and the forming of deep ocean volcanic ridges, help to move the plates across the Earth's surface.

What part of the earths mantle that flows and moves the plates of the earth?

Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.


What is The scientific name for the earths upper mantle?

The scientific name for the Earth's upper mantle is "asthenosphere." It is a layer of the Earth located beneath the lithosphere and is characterized by its partially molten state, which allows for the movement of tectonic plates.
