The movement of the currents plays a factor in the movement of the mantle.
Earth s interior convection currents. When the warm material reaches the surface it spreads horizontally. Heat generated from the radioactive decay of elements deep in the interior of the earth creates magma molten rock in the aesthenosphere. This process occurs repeatedly causing the currents to constantly flow.
As the core heats the bottom layer of mantle material particles move more rapidly decreasing its density and causing it to rise. Convection currents in the magma drive plate tectonics. The asthenosphere is a layer of the upper mantle that can flow very slowly.
Convection currents in earth s mantle are caused by the rise of hot material rising towards the crust becoming cooler and sinking back down.

Convection currents within earth s mantle form as material near the core heats up. The soft plastic material of the asthenosphere slowly rises spreads out and pushes cooler material out of the way. The earth is made out of a number of different layers and though we live on the crust of the earth there are miles of earth beneath our feet.
