What is at the edge of the continental shelf?
continental shelf, a broad, relatively shallow submarine terrace of continental crust forming the edge of a continental landmass. 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.
What is the edge of the continental shelf called?
shelf break
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 true of the continental shelf?
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an insular shelf.
What begins at the edge of the continental shelf?
shelf break underwater edge of a continental shelf, where it begins a rapid slope to the deep ocean floor.
Is the Deepest Indian Ocean Trench?
The recently named Factorian Deep, located at the southern end of the trench, is 7432 m deep. The Java Trench, in the eastern Indian Ocean, is more than 4000 km long….Five deepest points of the world’s oceans.

What is the outer edge of the continental margin?
The continental margin is the submerged outer edge of a continent. It is generally divided into two sections: the continental shelf and the continental slope. The continental shelf is the region that extends seaward from the shoreline to a sharp drop-off that marks the beginning of the continental slope.
Which of the following marks the true edge of a continent?
The portion of the continental margin that marks the true edge of the continent is the: continental slope.
What is true about the relationship of coastal plains and continental shelves?
What is true about the relationship of coastal plains and continental shelves? a. Coastal plains were part of the continental shelves that have been exposed by the fall of sea level. Continental shelves are submerged portions of coastal plains that were exposed during the peaks of the ice ages.
What ocean begins at the edge of the continental shelf and then extends outward into deeper water?
The open ocean begins at the edge of the continental shelf and extends outward.
What ocean zone begins at the edge of the continental shelf and then extends?
The neritic zone ([Figure 2]) extends from the margin of the intertidal zone to depths of about 200 m (or 650 ft) at the edge of the continental shelf. When the water is relatively clear, photosynthesis can occur in the neritic zone.
What is the deepest part of the world?
The Mariana Trench
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.
