→Convection Currents
===Convection CurrentsMeaning===Convection ‘’’Convection currents’’’ are powered by changes in [[Temperature|temperature]]. As [[Magma|magma]] near the core of the earth heats up it rises towards the earth’s [[Crust|crust]]. When the [[Magma|magma]] that has risen reaches the plates it becomes [[Displacement|displaced]] and moves horizontally. As the [[Magma|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 [[Tectonic Plate|plate]] movement that occurs in [[Tectonic Plate Margin|plate margins]].
