WebJun 18, 2024 · The theory is that the heat from the interior of the earth creates convection currents in the semi liquid mantle. These convection currents push new crust up from the mantle at the divergent boundaries. The new crust creates pressure pushing the plates at the divergent boundary apart. WebMantle convection is the driving mechanism for plate tectonics,which is the process ultimately responsible for producing earthquakes,mountain rangers and Volcano on Earth.Mantle convection is also important on venus and mars. 18. Make a convection pamphlet Answer: A. Convection currents are the result of differential heating.

Descending slabs would then cause their attached plates to move rapidly, as in the Elsasser model. spencers hot water heaters
