Question

continental- continental plate collisions produce_______
very tall mountains
island arcs
deep sea trenches
rift valleys

Explanation:

When continental - continental plates collide, due to their similar densities, neither plate is subducted. Instead, the crust is compressed and pushed upwards, forming very tall mountain ranges. Island arcs are formed by ocean - ocean or ocean - continental plate collisions with subduction. Deep sea trenches are created at ocean - ocean or ocean - continental subduction zones. Rift valleys are formed by the divergence of tectonic plates.

Answer:

Very tall mountains
