Its B. At the point when this happens gravity pulls the weight lithosphere far from the mid-sea edge, down the inclining asthenosphere, which, thusly, enables new liquid magma to well up. Another drive, that for a few plates surpass edge push, is piece pull, where the heaviness of a subducting section pulls the plate at the surface along.
the processes that move tectonic plates over the surface of the Earth are: B. Ridge push and slab pull
Ridge push created a movement that elevate the height of the tectonic plates while the slab pull created a movement that reduce the height of the tectonic plates
