What is the extent of the continental shelf?

A continental shelf typically extends from the coast to depths of 100–200 metres (330–660 feet). It is gently inclined seaward at an average slope of about 0.1°. In nearly all instances, it ends at its seaward edge with an abrupt drop called the shelf break.

What is beyond the continental shelf?

Continental slope, seaward border of the continental shelf. This system is an expression of the edge of the continental crustal block. Beyond the shelf-slope break, the continental crust thins quickly, and the rise lies partly on the continental crust and partly on the oceanic crust of the deep sea.

Where does the continental shelf extend?

Article 76(1) provides that the continental shelf extends to “the outer edge of the continental margin or to a distance of 200 nautical miles,” whichever is further.

Which ocean has the highest percentage of its area made up of continental shelves?

Whilst the Antarctic (Southern Ocean) shelf has the highest fraction of shelf area in the high-relief category at 69.3%, the Arctic shelf has a greater fraction of low relief shelf (45.1%) than any other ocean region.

Which is the edge of a continent under the ocean?

A continental shelf is the edge of a continent that lies under the ocean. Continents are the seven main divisions of land on Earth. A continental shelf is the edge of a continent that lies under the ocean. Continents are the seven main divisions of land on Earth.

Which is the best description of the continental shelf?

CONTINENTAL SHELF. A gently sloping, shallow area of the ocean floor that extends outward from the edge of the continent. CONTINENTAL SLOPE. An incline leading down from the edge of the continental shelf. SEAMOUNT. A mountain on the ocean floor that is completely underwater.

Which is the shallowest part of the ocean?

The region of shallow water in the ocean that extends from the low-tide line out to the edge of the continental shelf. The area of the ocean beyond the edge of the continental shelf. A bundle of rootlike strands that attaches algae to the rocks. A ring-shaped coral island found far from land.
