Question

question 9 of 10
an active continental margin may have a ______, while a passive margin generally does not.

a. continental shelf
b. rise
c. trench
d. continental slope

Explanation:

Active continental margins are associated with tectonic activity. A trench is a deep, narrow depression in the ocean floor that forms at subduction zones (where one tectonic plate is forced under another). Active continental margins are often located near subduction zones. Passive continental margins are not near plate boundaries and do not have trenches. Continental shelves, rises, and slopes are features that can be present in both active and passive margins (though their characteristics might vary in some aspects, but the key differentiating feature here is the trench).

Answer:

C. trench
