Gi Earth Plate 600x600x6mm

Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.The tectonic plates are part of the water cycle of the Earth. Water is bound in the minerals of the rocks that make up the plates. The plates bring water down into the Earth when they subduct, but much of that water is released, for instance at volcanic eruptions.
