An active continental margin is found on the leading edge of the continent where it is crashing into an oceanic plate. Passive continental margins are found along the remaining coastlines.

Q. What are the three divisions of the continental margin?
The continental margins consist of three portions: (1) the continental shelf which has shallow water depths rarely deeper than 650 ft) and extends seaward from the shoreline to distances ranging from 12.3 miles to 249 miles, (2) the continental slope where the bottom drops off to depths of up to 3.1 miles, and (3) the …
Q. At what depth does the continental margin flatten out?
The continental margin In the Atlantic Ocean, continental margins have a shelf that is broad and flat and reaches a depth of 100 m. The slope is the steep transitional area between the shelf and rise, and it lies between depths of 100 and 2,500 m.
Q. Why is the continental shelf considered the richest part of the ocean?
Continental shelves only make up about 6% of the ocean’s surface area, but they are biologically one of the richest parts of the ocean; their shallow depth prevents nutrients from sinking out, and their proximity to the coast provides significant nutrient input.
Q. What would be created when two plates under the ocean collide with each other?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs. Examples include the Mariana Islands in the western Pacific Ocean and the Aleutian Islands, off the coast of Alaska.
Q. Where is an example of a divergent boundary?
The mid-Atlantic ridge is an example of a divergent boundary, where the Eurasian Plate that covers all of Europe separates from the North American Plate. This underwater mountain range is constantly growing as new crust is formed. Further up that same boundary, it passes through Iceland.
