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.
Convection currents occur in the mantle of the earth. They can affect the crust and the life above it, though.

Heat transfer by convection currents takes place in the Earth's mantle, which is a layer below the crust and above the core. The mantle is composed of hot, flowing rock that undergoes convection due to heat from the Earth's core. This movement of the mantle drives tectonic plate movement on the Earth's surface.
Convection currents move in the Mantle.
The upper mantle contains convection currents that move the tectonic plates.

Scientists believe that convection currents flow through the Earth's mantle, which is the layer of hot, flowing rock beneath the Earth's crust. These currents are driven by heat from the Earth's core and cause the movement of tectonic plates at the surface.
The asthenosphere is the layer of the Earth directly below the brittle lithosphere, made of solid rock with a small percentage of melt, which is under tremendous pressure and temperature conditions. It performs and moves in a ductile fashion (highly viscous) even though it is considered rock, and does not break while under stress, but can move due to convection currents of heat arising from Earth's interior.
