Unformatted text preview: Describe. (3pts) Plates are destroyed along convergent plate boundaries where the edge of one plate may subduct (descend beneath the edge of another plate) back into the mantle or both plates may crumple and merge to form a mountain belt. Results from flux melting from addition of fluids. 6. Write down the types of plate boundaries and how do they differ from each other? (3 pts) Divergent-two plates move apart. Results in upwelling of material from the mantle to create new oceanic crusts. Decompression melting occurs when there is a decrease in pressure and an increase in temperature. Convergent- two plates moving toward each other. One plate moves beneath another plate. Transform-two plates slide past each other. Transform fault between oceanic plates...
