1. what can be found off setting mid ocean ridges? A. Dikes B. subduction zone C. Accretionary wedges D. Transform boundaries

2. At what type of boundary are accretionary wedges found? A. Convergent B.Divergent C.Transform

3. Which type of convergent boundary creates the tallest mountain? A.Continental-Contintal B. Ocean-Continental C.Ocean-Ocean

Solution

1. B. subduction zone: The occurence of ridge push happens when the growing bulk of the ridge pushes the rest of the tectonic plate away from the ridge which is mostly towards a subduction zone.

2. A. Convergent: Accretionary wedges are formed from the sediments which are accreted onto the non-subducting tectonic plate at a convergent plate boundary.

3. A. Continental-continental: The continental plates converge, buckle and compress to form tall mountain ranges. Some of the tallest mountain ranges like the Himalayas were formed as a result of a continental-continental convergent boundary.
