which description tells two processes scientists think move earth lithosphere plates A gravity acting on the edges of plates and friction between the plate and the astrosphere, B convection in the mantle and pressure of magma on the edge of the plate, C gravity acting on the edges of plates and convection in the mantle, D friction between the plate and the asthenosphere and pressure of magma on the edge of the plate

The correct description that tells two processes scientists think move Earth's lithospheric plates is C: gravity acting on the edges of plates and convection in the mantle.
Gravity pulls the edges of the plates downward (slab pull), and convection in the mantle generates currents that can push the tectonic plates around.
