The steeper part of a continental margin that slopes down from a continental shelf towards the abyssal plain 12 a current moving down downhill along the bottom driven by the weight of the sediment within it 12 the area at the bottom of the continental slope where it transitions to the abyssal sea floor 12.

. The average depth is not more than 150-200 metres. The continental shelves are not considered part of the ocean floor proper but as the flooded margins of a continent. A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea.

On their outer edge a continental slope falls away to the much deeper sea floor. Continental Shelf part of a continent that extends underwater to the deep ocean floor Continental Slope the sometimes steep descent of the continental shelf to the ocean floor Continental Rise large piles of sediment at the base of the continental slope Continental Margin. Continental shelf is the shallow portion of the ocean which lies close to the continental margin.

In others it extends for hundreds of miles. The continental shelf is a border of a continent submerged under water that slopes gradually and extends to a point of the deep ocean basin. The term continental shelf is used by geologists generally to mean that part of the continental margin which is between the shoreline and the shelf break or where there is no noticeable slope.

A are unaffected by surface weather. Satellites are used to map the ocean floor because they _____. It is the shallowest part of the ocean The shelf normally ends at a very steep slope which is called the shelf break.

The shelf typically ends at a very steep slope called the shelf break. The continental shelves are covered with variable thicknesses of. From the break the shelf descends toward the deep ocean floor in what is called the continental slope.

Learn vocabulary terms and more with flashcards games and other study tools. This shelf extends from the coastline of a continent to a drop off point called the shelf break. The average width of continental shelves is about 80 km.

From the break the shelf descends into the deep ocean floor. The geology of continental shelves is often similar to that of the adjacent exposed portion of the continent and most shelves have a gently rolling topography called ridge and swale. Ocean basin floor C.

No they are part of the continents. Water depth over the continental shelves averages about 60 meters 200 feet. Continental shelves are part of the deep-ocean floor.

The continental shelf is an area of relatively shallow water usually less than a few hundred feet deep that surrounds land. The gradient of the continental shelf is 1 or even less. Under the United Nations Convention on the Law of the Sea the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a particular country to which it belongs.

The Continental shelves consist of about 8 percent of the entire area which is covered by oceanic landforms. The continental shelf is the stretched margin of all continent occupied by comparatively shallow gulfs and sea. Structure of Continental Zone A continental shelf extends from the coastal area to the depths of around 100200 meters that is approximately 330660 feet.

Broad continental shelf b deep-sea trenches c shallow coastal waters d thick sediment accumulation. Mineral-rich water heated by newly formed oceanic crust escapes through cracks in the ocean floor called __. Deep-ocean trenches are located mostly in the middle of ocean basins.

Continental shelf continental slope continental rise deep ocean basin abyssal plain deepsea trench and seamount. The continental margin between the continental shelf and the abyssal plain comprises a steep. It is narrow or nearly nonexistent in some places.

A continental shelf is the edge of a continent lying beneath the ocean. Are continental shelves part of the deep-ocean floor. These extensions of continents are shallow mostly flat regions of Earths crust under the sea along the coastlines.

The Atlantic Ocean covers the greatest area of all the worlds oceans. High evaporation rates in the subtropics about 30 degree latitude cause the surface-ocean water to have a lower-than-average salinity. Click to see full answer.

The shelf surrounding an island is known as an insular shelf. Continental ShelfContinental Shelf is the gently sloping seaward extension of the continental plate. Starting from land a trip across an ocean basin along the seafloor would begin with crossing the continental shelf.

Underwater continental crust makes up part of the deep ocean basin. Start studying Ocean Floor Review. Conservationists governments and energy companies all seem to take a keen interest in the oceans continental shelves.

They are gently inclined towards the sea at an average slope of approximately 01. The shelf break is where the underwater edge of a continent shelf begins to rapidly slope downwards towards the ocean floor depths. It is actually a part of the continent sloping gently towards the sea floor.

The Continental Shelf of all oceans together covers 75 of the total area of the oceans. Even though they are underwater continental shelves are part of the continent. Much of these shelves were exposed by drops in sea level during glacial periods.

Continental shelf a gently sloping shallow area of the ocean floor that extends outward from the edge of a continent Continental slope the steep gradient that leads to the deep-ocean floor and marks the seaward edge of the continental shelf Submarine canyons deep steep-sided valleys cut into the continental slope Turbidity currents. The waters along the continental. Continental shelf a broad relatively shallow submarine terrace of continental crust forming the edge of a continental landmass.

Continental shelves make up about 8 percent of the entire area covered.
