What is the sharp drop from the continental shelf to the continental rise?

What is the sharp drop from the continental shelf to the continental rise?

In nearly all instances, it ends at its seaward edge with an abrupt drop called the shelf break. Below this lies the continental slope, a much steeper zone that usually merges with a section of the ocean floor called the continental rise at a depth of roughly 4,000 to 5,000 metres (13,000 to 16,500 feet).

What is between the continental shelf and the continental rise?

The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope.

What is the steep drop after the continental shelf?

Many previously unknown features of the seafloor were discovered. Extending out from a continent’s edge is a gently sloping, shallow area called the continental shelf (F). At the edge of the shelf, the ocean floor drops off in a steep incline called the continental slope (A).

What is the name of the boundary that separates the continental shelf from the continental slope?

The gently sloping region of the continental margin that extends seaward from the shoreline to the continental shelf break. Continental shelf break: The outer edge of the continental shelf at which there is a sharp drop-off to the steeper continental slope.

Is the continental slope steep?

Compared with the relatively flat surface and gentle inclination of the continental shelf, the continental slope dips steeply into the ocean basins at an average angle of around 4° although it may be much steeper locally (35 to 90°).

Which part of the shallow ocean descends sharply away from the continental shelf Brainly?

Mid -ocean ridge.

What is the regular rising and falling of sea level due mainly to the pull of the moon called?

Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of the Earth.

Where does the continental shelf begin and end?

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 extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope.

Is the continental slope part of the continent?

A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope. Even though they are underwater, continental shelves are part of the continent.

Why are the waters of the continental shelf so shallow?

Once that land was submerged, the valleys filled with seawater, creating fjords and channels. Ships use channels to navigate safely through shallow water. Because the average depth of water over a continental shelf is around 200 feet, these shallow waters are well-lit and warm, creating the perfect environment for plant life to flourish.

Where is the widest continental shelf in the world?

The widest continental shelf on the planet extends to about 1,210 km (in miles it is 750 miles) it is located off the coast of Siberia, Russia, and into the Arctic Ocean. The Continental shelves serve as an extension of the coastal plains.
