10. plate tectonies is a result of the earth's internal heat engine, powered by a. the sun b. gravity c. heat flowing outward from the earth's interior that drives convection

c. heat flowing outward from the earth's interior that drives convection

Explanation:

Plate tectonics is a larger consent of the rotational motion of different slabs on the surface of the earth and is in direct relation to the energy flows from the interior of the planet's core towards the outer layer of the earth this energy is thus needed to form various physical features on the surface of the earth. Also, solar radiation acts as a denudation factor that destroys all that is formed above the surface of the earth through the rotation of the plate and the earth internal thermodynamics. Plate tectonics is thus considered to be a storehouse of earth internal heat system that is powered by the plate boundaries from the earth and collision, construction and transforms shifts that have a direct bearing on the above. Earth gravitational pull is only due to the string forces of this interlayer the core and the convective motion of the above two layers.
