The hot rock rises gradually towards the crust. As it rises, it moves further away from its heat source at the core and starts to cool down. When it reaches the crust, it is forced out sideways because it cannot easily pass through the solid rock above it. the proof with simon hill

WebOct 3, 2024 · We can define convection currents as a natural process of heat transfer involving the movement of energy and heat from one place to another. We can exemplify it by observing that we feel hotter when we place our hands above a campfire. This happens due to convection currents. What causes convection currents in Earth’s mantle? WebConvection definition, the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. See more.

WebFeb 28, 2024 · They move because of something called convection currents. Convection currents push these plates together and apart. Convection currents are created by rising and falling heat in the earth's mantle. When two oceanic plates are pushed away from each other, magma rises to the surface between the plates and creates a ridge. 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.
