Question

boundaries. the type of boundary between certain plates is indicated using arrows.

at which plate boundary is old crust being destroyed?
choose 1 answer:

Explanation:

Old crust is destroyed at convergent plate boundaries, where two plates move toward each other (indicated by arrows pointing toward one another). Looking at the map:

1. The boundary between the North American Plate and Pacific Plate has arrows pointing toward each other, showing convergence. At this type of boundary, denser oceanic crust subducts under continental crust, and the subducted crust is destroyed in the mantle.
2. The Nazca-South American boundary shown with opposing arrows is a divergent boundary (crust created), and the Antarctic-South American boundary with opposing arrows is also convergent, but the North American-Pacific boundary is clearly marked with inward-pointing arrows matching the convergent pattern for crust destruction.

Answer:

The boundary between the North American Plate and the Pacific Plate
