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.

What are the 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 is the largest feature of the ocean floor?
oceanic ridge, continuous submarine mountain chain extending approximately 80,000 km (50,000 miles) through all the world's oceans. Individually, ocean ridges are the largest features in ocean basins.
What are three features on the ocean 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 is the most important topographic feature of the ocean floor?
The important features are the extensive continental shelves less than 250 m deep (pink); the vast deep ocean plains between 4,000 and 6,000 m deep (light and dark blue); the mid-Atlantic ridge, in many areas shallower than 3,000 m; and the deep ocean trench north of Puerto Rico (8,600 m).
What are 4 types of ocean floor?
- Continental shelf. Starting from land, a trip across an ocean basin along the seafloor would begin with crossing the continental shelf. ...
- Abyssal plains. Continuing your journey across the ocean basin, you would descend the steep continental slope to the abyssal plain. ...
- Mid-ocean ridge. ...
- Ocean trenches.
Which feature is found near the ocean?
The deepest places of the ocean are the ocean trenches , many of which are located around the edge of the Pacific Ocean. Chains of volcanoes are also found in the center of the oceans, such as in the area of Hawaii. Flat plains are found on the ocean floor with their features covered by mud.
Which part of the ocean floor is most useful to the man?
The part of ocean floor that is most useful to the man is Continental Shelf . A continental shelf can be defined as a part of continent that is submerged in shallow water.
What are five ocean floor features?
Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge .
What is the ocean floor called zone?
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers.
Is the ocean floor sand?
The simple answer is that not all of the ocean floor is made of sand . The ocean floor consists of many materials, and it varies by location and depth. ... In the deepest parts of the ocean, you'll find layers of Earth's crust make up the ocean floor. These deepest layers are made up of rock and minerals.
What color is the ocean floor?
Most of the light that is reflected by clear, open ocean water is blue , while the red portion of sunlight is quickly absorbed near the surface. Therefore, very deep water with no reflections off the sea floor appears dark navy blue.
What part of the ocean is 5200 m?
With maximum depth exceeding 17,000 feet (5,200 m), the seafloor's most distinctive feature is the Tasman Basin .
Is the ocean floor flat?
The oceans' floors are not a flat, sandy expanse – they are every bit as varied as the landscapes above water, with plunging valleys and huge mountains.
What are the three major topographic units of the ocean floor?
Physiography and bathymetry (submarine landscape) allow the sea floor to be subdivided into three distinct provinces: (1) continental margins, (2) deep ocean basins and (3) mid-oceanic ridges .
