Question

Quizplus · Accepted Answer

The outer edge of the continental shelf is defined as the point where there is a rapid steepening of the gradient, marking the transition from the relatively shallow and gently sloping shelf to the deeper and steeper continental slope. Option B is incorrect because the depth at which the shelf ends can vary depending on factors like tectonic activity and sea level changes. Option C is incorrect because the gradient doesn't become gentle at the outer edge of the continental shelf. Option D is incorrect because meeting an oceanic ridge is not a defining characteristic of the outer edge of the continental shelf.
