Question 14(multiple choice worth 3 points) crust is recycled at hot spots. o mid-ocean ridges. trenches. rifts. transform faults.

trenches

Explanation:

Crust recycling is the earth process by which surface matter from the land sphere is recycled into the mantle by the process of subduction or delamination. The crustal signs in mantle-derived rocks are thus a proof of the recycling. Most of this process happens through the mid-oceanic ridges. The development of whole mantle convection components and layered by mantle convection proponents. Evidence is suggested through the Seismic tomography and Stable isotopes that help in understanding the different layers on the earth and keeps track of the movements within the earth's crust. Dome group of researchers can find out that 5 to 10 % of the upper mantle is composed of recycled crustal matter.
