Question

Why does oceanic crust subduct underneath continental crust at a convergent plate boundary? Group of answer choices oceanic crust is less dense (so it rises) and thinner. oceanic crust is less dense (so it rises) and thicker oceanic crust is more dense (so it sinks) and thinner. oceanic crust is more dense (so it sinks) and thicker

Answer 1

Answer:

oceanic crust is more dense (so it sinks) and thicker

Explanation:

• The oceanic crust is more denser than continental crust and hence it sinks easily below the continental crust the continental crust is more thicker than the oceanic crust that is 20-70 km as compared to 7-10 km. The process that results in sinking is associated with the subduction and hence upon colliding the plate sinks deep into mantel.
