Question

plate tectonics: convergent bounda... of deep oceanic trenches. exemplified by the mariana trench, one of the deepest points on earths surface, these subduction zones generate intense geological activity, including the melting of crust, and contribute to the dynamic processes that shape our planets seafloors. what is the primary outcome of oceanic - oceanic convergence? creation of deep oceanic trenches formation of mountain ranges expansion of continental landmasses

Explanation:

Ocean - ocean convergence occurs when two oceanic plates collide. The denser plate subducts beneath the other, leading to the formation of deep - oceanic trenches. Mountain ranges form mainly from continent - continent or continent - ocean convergence, and expansion of continental landmasses is not a primary outcome of ocean - ocean convergence.

Answer:

creation of deep oceanic trenches
