20. The action that describes where one plate dives (subducts) under less
dense crust to be recycle back into the asthenosphere describes:
A. Divergent plate boundaries
B. Convergent plate boundaries
C. Transform plate boundaries



Answer :

Final answer:

Subduction zones form at convergent plate boundaries where one plate dives beneath another, leading to the recycling of crustal rocks.


Explanation:

Subduction zones form at convergent plate boundaries where one plate dives beneath another, typically involving an oceanic plate subducting under a continental plate or another oceanic plate.

Subduction zones lead to the recycling of crustal rocks back into the asthenosphere, where heavier, more dense oceanic plates collide with lighter, less dense continental plates, resulting in the process of subduction.
