Which pair of processess do scientists think move Earth's lithospheric plates?

• gravity acting on the edges of plates and friction between the plate and the asthenosphere

• friction between the plate and the asthenosphere and pressure of magma on the edge of the plate

What is ridge push?

• cooler, denser crust sinks into the mantle

• when edges become denser and gravity pulls them downward and away from one another

• currents just beneath Earth’s crust flow very slowly, causing movement in the plates above them

• folding and crumpling and sliding upward creating mountains
