Question

When a plate carrying continental crust converges with a plate carrying oceanic crust: A. a divergent plate boundary forms B. the continental plate sinks into the mantle C. the oceanic plate floats above the continental plate D. the oceanic plate sinks beneath the continental plate and dives into the mantle

Answer 1

Answer:

Option (D)

Explanation:

A plate containing a continental crust is usually known as the continental plate and the plate containing an oceanic crust is known as the oceanic plate.

The collision of the oceanic plate and continental plate results in the formation of a convergent plate boundary where the heavier oceanic plate subducts below the lighter continental plate and moves into the deeper mantle zone. It is because the oceanic crust is comprised of denser minerals such as olivine, feldspar (plagioclase) and pyroxene, whereas, the continental crust is made up of less dense minerals such as silicon, iron, aluminum, and many more.

Thus, the correct answer is option (D).
