Answer:
True
Step-by-step explanation:
Convection current in the earth’s mantle are the causative factor of “movement of tectonic plates”. Convection currents basically affect a liquid, gas or a molten material. Since the mantle of earth consists of molten rock, it is heated up by the convection currents and thus allowed to flow. Flowing of magma with in the earth’s mantle causes the movement of tectonic plates .
Therefore , the statement "Convection currents within the Earth cause plate tectonics due to the movement of the mantle" is true.
