GEOLOGY

Detailed explanation-1: -Magma is the molten rock below the crust, in the mantle. 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.

Detailed explanation-2: -Convection currents in the mantle occur due to density differences caused by variations in temperature and composition. It consists of hotter and less dense mantle material rising while colder, denser material sinks.

Detailed explanation-3: -The forces that drive Plate Tectonics include: Convection in the Mantle (heat driven) Ridge push (gravitational force at the spreading ridges) Slab pull (gravitational force in subduction zones)
