A subduction zone is where one plate is pulled under the edge of another and occurs in convergent plate boundaries. Which type of crusts are involved in the subduction zone? a. continental-continental
b. continental-oceanic
c. oceanic-oceanic

b. Continental-oceanic

Explanation:

The Earth's crust has been divided into a series of plates. These plates move at a different rate or speed in different directions.

These plates are divided by the boundary between them which are of three types: convergent, transform and divergent.

The convergent boundaries are the one which moves toward each other and the based on the crust they are of three types: continent-continent, ocean-ocean and ocean-continent.

In ocean-continent boundaries, the oceanic plate is denser compared to the continental plate is lighter as a result of which during the process of subduction the oceanic plate sinks beneath the continental plate towards the mantle and melts.

Thus, Option-B is the correct answer.

(75°f − 32) × 5/9 = 23.889°c
