What is the continental margin?

the zone where heated mineral-rich water joins the surrounding cold water

the zone where trenches form islands

the zone of transition between a continent and the adjacent ocean basin floor

the zone where hot spots form guyots

The Continental margin is the zone of transition between a continent and the adjacent ocean basin floor.

Explanation:

The continental margin is located in the ocean and it is a relatively shallow water area found in proximity to a continent. There are three different features to the continental margin: the continental rise, the continental slope, and the continental shelf. Continental margins that are on the edges of tectonic plates are usually narrow. They will have steep continental slopes. In the case of such continental margins that are on edges of tectonic plates like the Pacific Rim, there are continental rises that are either poorly developed or not perceptible at all.
