What is the most important topographic feature of the ocean floor?
The main features of the Pacific Ocean floor are the continental slopes, which drop from about 200 m to several thousand metres over a distance of a few hundred kilometres; the abyssal plains — exceedingly flat and from 4,000 m to 6,000 m deep; volcanic seamounts and islands; and trenches at subduction zones that are …
What is the most prominent feature at the mid-ocean floor ridges?
The plate boundary of the Mid-Oceanic Ridge comprises an alternation of spreading centers (or axes or accreting plate boundaries) interrupted or offset by a range of different discontinuities, the most prominent of which are transform faults.
What are the 7 features of the ocean floor?
There are nine main features of the ocean floor which include (1) continental shelf, (2) continental slope, (3) continental rise, (4) abyssal plains, (5) abyssal hill, (6) mid-ocean ridges, (7) seamounts, (8) deep ocean trenches, and (9) volcanic islands.
What are the three main features of the deep sea floor?
The bottom of the deep sea has several features that contribute to the diversity of this habitat. The main features are mid-oceanic ridges, hydrothermal vents, mud volcanoes, seamounts, canyons and cold seeps. Carcasses of large animals also contribute to habitat diversity.
Which is one feature of the ocean floor found in the open ocean?
Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots. The basins also contain a variable amount of sedimentary fill that is thinnest on the ocean ridges and usually thickest near the continental margins.
What feature is common in all oceans?
Ocean basins are composed of the seafloor and all of its geological features (such as islands, trenches, mid-ocean ridges, and rift valleys) and vary in size, shape, and features due to the movement of Earth’s crust (lithosphere). Earth’s highest peaks, deepest valleys, and flattest plains are all in the ocean.
Is the most prominent feature on earth’s surface and are found in every?
The ocean, which covers over two-thirds of the earth’s surface, is the most prominent feature on our planet.
Which is characteristic of mid-ocean ridges?
A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary.
What are the 4 main features of the ocean floor?
Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge. The ocean floor is rich in resources. Living things on the ocean floor are used for food or medicines.
What are the features of sea floor?
Features of the ocean include the continental shelf, slope, and rise. The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
What are 4 features of the ocean floor?
Which feature of the ocean floor includes deepest parts?
The deepest parts of the ocean are within the subduction trenches, and the deepest of these is the Marianas Trench in the southwestern Pacific (near Guam) at 11,000 m (Figure 18.5).
