source of heat that drives mantle convection

What Causes Convection Currents in the Earth’s Mantle?

Mar 24, 2020· Convection currents in Earth’s mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle. The convection currents also help transfer heat from

Quick Answer: Why Are There Convection Currents In The Mantle

Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km.
