What are the 5 features of ocean basins?
Ocean ridges, deep-sea trenches, abyssal hills, fracture zones, seamounts, and guyots are some of the major features of an ocean basin.
What are the four major ocean basins parts?
Even though there is one world ocean, it has traditionally been divided into four major ocean basins: the Arctic, the Atlantic, the Indian, and the Pacific.
What are the 3 major ocean basins?
The continents, which cover 29.2% of the earth’s surface, break up the ocean into the three basins, which we call the Atlantic, Pacific, and Indian oceans.
What is continental shape?
Continental margins are the zones between the ocean basin and the mass of the continent. The continental shelf is the underwater region from the continental margin to the shoreline.
What are the features of continental margin?
The continental shelf is the relatively shallow water area found in proximity to continents. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area.
What are continents and ocean basins made of?
The reason for the different levels is that the continents and ocean basins are made up of different kinds of rock. Continental rocks are rich in the light-colored minerals quartz and feldspar, which combine to make up the principal kind of rock in the continent, which is granite (Figure 2-2).
What are the four main ocean basins which is the largest and which is the smallest?
The Atlantic basin is the second largest basin, followed by the Indian Ocean basin, the Southern Ocean, and finally the Arctic Ocean basin.
What are the 6 ocean basins?

- Atlantic Ocean Basin.
- Indian Ocean Basin.

What is ocean sediment?
Ocean sediments are products of weathering, erosion, and transportation through layered streams of sand, silt, mud (clay), and other materials (carbonates) further precipitate from solution.
What are the 4 parts of the continental margin?
The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area.
What do you mean by continental margin in oceanography?
Continental margins. refer to the region of transition from the land to the deep seafloor, i.e. between. continental. and. oceanic crust. . In an. active continental margin. , the boundary between the continent and the ocean is also a.
How are the passive margins of the continent formed?
The passive continental margins are formed under divergent plate boundary setting. These are aseismic (less seismic) and often referred as the Atlantic-type margins having a distinct transition zone between the continental and oceanic crustal regions. ii.
How are the margins of the continental shelf formed?
Transform continental margins (sheared margins) are formed due to lateral plate movements or shearing motions during the continental breakup process in the divergent margin setting.
What are the features of an active margin?
Active margins have similar features to passive margins, but the plate boundary affects the properties of the features. Active margins, like the Pacific coast of North America, have narrower shelves, steeper slopes, and little to no rise, particularly in
