What is the function of the mantle of the Earth?
The Mantle Earth’s mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (>90%) is convected through the mantle to the base of the lithosphere.

The mantle is much thicker, nearly 3,000 km thick, while the crust is on average about 40 km. Mainly due to its cooler temperatures, the crust is stiffer and more rigid. The mantle actually “flows” and convects on long geologic timescales.
