Question

Relief features that are found in the oceans include__
A. Submarine Ridges
B. Plateaus
C. Canyons
D. Terraces
E. All of these

Answer 1

Hint:
 Water occupies 70 percent of the surface of the planet, about 3 percent of which is freshwater. Oceans make up about 67 percent of the surface of the Earth.

Complete answer:
 In the shape of cliffs, basins, plateaus, ridges, canyons and trenches under the ocean water, the Oceanic relief features are. Such types are classified as Submarine Relief.
The ocean relief, such as Continental Shelf, Continental Slope, Continental Rise or Foot, Deep Ocean basins, Abyssal plains & Abyssal Hills, Oceanic Trenches, Seamounts and Guyots, can be divided into different sections.

These features of Oceanic Relief have a lot of importance, such as regulating the motion of sea water. It also affects the flow of the ocean in the form of tides and assists in navigation and fishing.

The relief characteristics of the oceans are somewhat different from the continental characteristics, as the Oceanic crust is less than 60-70- million years old, while the Proterozoic period is continental.

The ridges of submarines span hundreds and thousands of kilometres in length and cross several hundred kilometres in width.

To shape islands, some peaks also rise above sea level. Submarine ridges are relatively uncommon in the submarine continental margins and their formation is similar to the structure of mountains on the adjacent parts of continents.

Hence, the correct answer is option E.

Note:
A high, relatively flat elevation, which is greater than the surrounding relief with one or more relatively steep sides, is an oceanic or submarine plateau.
A canyon or gorge is a deep cleft between escarpments or cliffs resulting from weathering over geological time scales and the erosive action of a river.
A terrace consists of a geomorphic surface that is flat or gently sloping, called a tread, usually bounded on one side by a steeper ascending slope called a "riser" or "scarp".
