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.

WebConvection Currents The heat from the core causes the mantle to be heated at its base. 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. WebConvection currents are present everywhere, from the atmosphere to magma within the plates. The basic principle of a convection current is that warm air rises because of the extra energy it received in the form of heat …
