Simple Description

The part of the Earth below the crust

Further Detail

The Earth's mantle is solid but it can also flow. Convection currents in the mantle (which are caused by heat from radioactive decay) can cause the mantle to flow and they pull different tectonic plates apart - a process called "continental drift".
