What two ocean floor features are caused by plate boundaries?
As plates converge, one plate may move under the other causing earthquakes, forming volcanoes, or creating deep ocean trenches. Where plates diverge from each other, molten magma flows upward between the plates, forming mid-ocean ridges, underwater volcanoes, hydrothermal vents, and new ocean floor crust.
What are two ocean floor features?
Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge. The ocean floor is rich in resources. Living things on the ocean floor are used for food or medicines.
How much of the ocean floor is covered by continental slope?
About 8.5 percent of the ocean floor is covered by the continental slope-rise system. This system is an expression of the edge of the continental crustal block.
Which is a part of the ocean floor?
The Ocean Floor continued. CONTINENTAL SHELF, SLOPE, AND RISE There are three main parts of the continental margin: the continental shelf, the continental slope, and the conti- nental rise. The continental shelf is the part of the mar- gin that begins at the shoreline and slopes gently toward the open ocean.
Is the continental slope the same as the continental margin?
continental margin The broad, gentle pitch of the continental shelf gives way to the relatively steep continental slope. The more gradual transition to the abyssal plain is a sediment-filled region called the continental rise. The continental shelf, slope, and rise are collectively called the continental margin.

Which is the steepest part of the ocean floor?
The continental shelf is the part of the mar- gin that begins at the shoreline and slopes gently toward the open ocean. It continues until the ocean floor begins to slope more steeply. The depth of the continental shelf can reach 200 m. The continental slope is the steepest part of the con- tinental margin.
