__________ is the process in which material that is heated deep within the asthenosphere rises to displace cooler, less dense material near the surface.

Question

Quizplus · Accepted Answer

Convection is the process of heat transfer within a substance (in this case, the mantle) where hotter, less dense material rises and cooler, denser material sinks. In the case of plate tectonics, convection currents in the mantle are responsible for moving the plates around on the Earth's surface. As material rises from deep within the asthenosphere, it displaces cooler material nearer the surface, causing movement and deformation of the Earth's crust.
