Question

Quizplus · Accepted Answer

Passive continental margins are formed where two tectonic plates move apart, causing the continental crust to gradually subside into the oceanic basin. This creates a broad continental shelf, which is the shallow, gently sloping area that extends from the shoreline to the edge of the continental slope. Active continental margins, on the other hand, are formed where two plates converge and one is forced beneath the other. This results in a relatively narrow, steep continental shelf.
