What is the average depth of the shelf break?

What is the average depth of the shelf break?

A shelf break is characterized by markedly increased slope gradients toward the deep ocean bottom. The shelf break may be as shallow as 20 metres (65 feet) and as deep as 550 metres; the worldwide average depth is 133 metres.

What is continental shelf limit?

The continental shelf may not extend beyond 350 nautical miles (648 km) or, alternatively, more than 100 nautical miles (185 km) beyond the point at which the seabed lies at a depth of 2 500 metres.

How is the continental shelf measured?

The coastal State shall delineate the outer limits of its continental shelf, where that shelf extends beyond 200 nautical miles from the baselines from which the breadth of the territorial sea is measured, by straight lines not exceeding 60 nautical miles in length, connecting fixed points, defined by coordinates of …

What is the average depth of continental slope?

The continental slope extends from the shelf break to water depths typically of around 3,000–4,000 m where an abrupt change in gradient delimits the foot of slope.

How deep is the Atlantic continental shelf?

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.

What is the average depth of the Northern Australia continental shelf?

The Continental Shelf of Australia This shelf is relatively shallow, up of 200 meters deep compared to the thousands of meters deep in the open ocean, and extends outward to the continental slope where the deep ocean begins.

What is the depth of continental slope?

What is the average depth of continental slope in meter?

The world’s combined continental slope has a total length of approximately 300,000 km (200,000 miles) and descends at an average angle in excess of 4° from the shelf break at the edge of the continental shelf to the beginning of the ocean basins at depths of 100 to 3,200 metres (330 to 10,500 feet).
