WebMar 24, 2024 · Convection currents in Earth’s mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs … WebWhy does mantle convection occur? 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.
