Answer 2

"OPTION A-Older crust is melted at subduction zones."

Explanation:

In the subduction zone, the maritime hull ordinarily sinks into the mantle underneath lighter mainland outside. (Here and there, maritime hull might become so old and that thick that it breakdowns and immediately frames a subduction zone, researchers think.

In a subduction zone (like the Cascades or the Andes), where a maritime plate slides down under another plate, that down going piece delivers its water as it warms up. That water then, at that point, ascends into the mantle above it, making it dissolve at a lower temperature and, bam!
