WebWhen more weight is added to the crust, through the process of mountain building, it slowly sinks deeper into the mantle and the mantle material that was there is pushed aside (Figure 9.17, left). When that weight is removed by erosion over tens of millions of years, the crust rebounds and the mantle rock flows back (Figure 9.17, right). WebThe mantle allows the crust to move and also, in a way, drives the motion of the tectonic plates. The mantle is more or less solid rock, but the high temperatures (>1000°C / …

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface.
