What are some of the 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. Nonliving resources include oil, gas, and minerals.
What are the 3 features of the ocean basin floor?
The sea floor can be subdivided into three major features: (1) continental margin, (2) abyssal plain, and (3) Mid-Atlantic Ridge. The continental margin is itself comprised of the shelf, slope and rise. The margin is the portion adjacent to the continent and the transition to the deep ocean basin.
What are the 4 types of ocean floor?
Underwater landforms
- 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.
What are the 5 features of ocean basins?
A number of major features of the basins depart from this average—for example, the mountainous ocean ridges, deep-sea trenches, and jagged, linear fracture zones. Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots.
What are major geological features of the ocean floor?
There are many geologic features on the ocean floor. Trenches, ridges, rises, and islands are the result of continental or oceanic plate movement. Volcanic eruptions and earthquakes are also the result of tectonic plate movement.
Which feature of the ocean floor includes its 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).
Which feature of the ocean floor includes deepest parts?
deep-sea trenches
It closely resembles the surface of the moon with its features such as the abyssal plain, deep-sea trenches, and seamounts. The abyssal plain is the flat, deep ocean floor. A thick layer of sediment that covers the hills and valleys found in it. Deep-sea trenches are the deepest parts of the ocean.
What is the ocean basin floor?
ocean-basin floor The ocean floor in those parts of the oceans that are more than 2000 m deep. It occupies approximately one-third of the Atlantic and Indian Ocean floors, and three-quarters of the Pacific Ocean floor. A Dictionary of Earth Sciences.
