Meaning
Convection
‘’’Convection currents’’’ are powered by changes in temperature. As magma near the core of the earth heats up it rises towards the earth’s crust. When the magma that has risen reaches the plates it becomes displaced and moves horizontally. As the magma has been near the surface it starts to cool. The colder magma then returns to the core of the earth, finishing a circular motioned cycle known as a ‘’’convection current’’’. These ‘’’Convection Currents’’’ are responsible for all the plate movement that occurs in plate margins.
