WebSep 27, 2024 · Mantle convection is the slow, churning motion of Earth’s mantle. Convection currents carry heat from the lower mantle and core to the lithosphere. Convection currents also “recycle” lithospheric materials back to the mantle. Seafloor spreading occurs at divergent plate boundaries. WebConvection definition, the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. See more.
WebAtmospheric convection currents can be set up by local heating effects such as solar radiation (heating and rising) or contact with cold surface masses (cooling and sinking). Such convection currents primarily … WebConvection currents also stress the lithosphere above, and the cracking that often results manifests as earthquakes.
