The molten material found beneath the earth surface is termed magma. The mobile plate is the plate that divides the earth lithosphere. The plates are floating above the partially melted semi-plastic region is called Asthenosphere. The movement of several major and minor plates of the earth lithosphere is called plate tectonics. The internal heat source of earth driven convection current is the chief cause for the movement of earth lithospheric plates.
