WebSep 22, 2024 · Why does convection occur in mantle? Mantle convection occurs because relatively hot rocks are less dense and rise in a gravitational field while relatively cold rocks are more dense and sink. The rise of hot rocks advects heat upward while the fall of cold rocks advects cold downward; this counterflow is equivalent to an upward heat flux. WebThe mantle’s convective motions break the lithosphere into plates and move them around the surface of the planet. These plates may move away from, move by, or collide with each other. This process forms ocean basins, shifts continents, and pushes up mountains. Scientists study mantle convection, or the flow of hot rock in the Earth's deep … WebMar 30, 2024 · The cells are propelled by convection cells like mantle convection.

"WebThese plates move very slowly across the surface of the Earth as though they were on a conveyor belt. The convection currents in the much hotter mantle continually move the plates about 1/2 to 4 inches per year. When the plates move they collide or spread apart allowing the very hot molten material called lava to escape from the mantle. " - How does mantle convection occur
