This process occurs …
WebThe plate then moves due to friction between the convection current and the crust. The liquid rock cools, sinks and the process is repeated. Fig. 4 ... This occurs as the convection current of the mantle pushes the plates apart, generating a gap in between, causing magma to fill the gap and producing a new crust. ... WebNov 29, 2009 · Convection currents occur in any fluid in which there is a temperature differance. Most convection currents occur in the mantle, the layer of semi-liquid rock below the crust.
WebJul 5, 2024 · A convection current is a process that involves the movement of energy from one place to another. It is also called convection heat transfer. The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid .
WebDivergent Plate Boundaries. Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it.
