What are the 3 major ocean floor provinces?
three distinct provinces:
- continental margins.
- deep ocean basins.
- mid-ocean ridges.
What are the main areas of the 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. …

What are the three major regions of the ocean floor quizlet?
What are the three main regions of the ocean floor? The ocean floor regions are the continental margins, the ocean basin floor, and the mid-ocean ridge.
What are the 3 main parts of the continental margin?
The continental rise, continental slope, and continental shelf are the three basic components that actually make the entire structure of continental margins. The continental slopes and the continental shelves are structural constituents of continents even though they are below the surface of sea.
What are the provinces of the seafloor called?
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.
What are two main regions of the ocean floor?
Two major regions of the ocean floor are the continental margin and the deep-ocean basin.
What are the 3 zones of the ocean?
The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic, dysphotic, and aphotic zones.
- Euphotic Zone (Sunlight Zone or Epipelagic Zone) …
- Dysphotic Zone (Twilight Zone or Mesopelagic Zone) …
- Aphotic Zone (Bathypelagic, Abyssopelagic, and Hadopelagic Zones)
What are 4 types of ocean floor?
These relief features found on the ocean floor are called Submarine Relief. The ocean basins are broadly divided into four major subdivisions….They are;
- Continental Shelf.
- Continental slope.
- Abyssal plains.
- The ocean deeps/ submarine trenches.
Which of the following is not one of the three major regions of the ocean floor?
Which of the following is NOT one of the three major regions of the ocean floor? b. ocean basin floor. Which of the following is associated with down slope movements of dense sediment-rich water?
What is a submarine valley?
Submarine canyons – Submarine canyons are defined as “steep-walled, sinuous valleys with V-shaped cross sections, axes sloping outward as continuously as river-cut land canyons and relief comparable to even the largest of land canyons” (Shepard, 1963).
What regions make up the continental margin?
The continental margin is that part of the ocean floor at the edges of the continents and major islands where, just beyond the shoreline, it tapers gently into the deep sea. The continental margin is made up of the continental shelf, the continental slope, and the continental rise.
Where is the continental margin?
A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges.
What are marine provinces?
Marine provinces are specific geographic areas of the ocean delineated by common landform (i.e., coastal geology and position of the continental shelf) and water conditions (i.e., temperature, currents, wind patterns, and salinity ).
What’s under the ocean floor?

Which correctly lists the three main ocean zones quizlet?
There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone.
What is the 3 major zone?
They are the intertidalzone, neriticzone, and oceaniczone.
What are three ocean zones?
There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone. Distance from shore influences how many nutrients are in the water.
How many major areas does the ocean floor have?
The ocean floor or seabed can be divided into three major regions: the continental margins, abyssal plains, and mid-ocean ridges.
What are the three major regions?
There are three types of regions: formal, functional, and vernacular.
How did the Congo Canyon form?
Evidence seems to suggest that the principal agents responsible for the formation of submarine canyons are marine processes, most notably the erosion and transportation of sediments by turbidity currents activated by the slumping of unconsolidated rock material near the heads of the canyons.
What is a canyon on the ocean floor called?
submarine canyon, any of a class of narrow steep-sided valleys that cut into continental slopes and continental rises of the oceans. Submarine canyons originate either within continental slopes or on a continental shelf.
What is a flat region of deep ocean basins?
Abyssal plain: Flat or very gently sloping area of the deep ocean basin floor.
What are three major features of a passive continental margin?
The features comprising passive continental margins include the continental shelf (the flooded extension of the continent), the continental slope (has the steepest slope), and the continental rise.
Where is the boundary between continental crust and oceanic crust?
Today, tectonic activity is responsible for the formation (and destruction) of crustal materials. Earth's crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity.
What are the two marine provinces?
The pelagic zone is divided into two provinces: the neritic province corresponds to all of the water from the low tide line to the shelf break, while the oceanic province represents all of the other water in the open ocean regions.
What is the ocean floor made of?
The seafloor contains deposits of minerals that we use in everyday life such as copper, zinc, nickel, gold, silver, and phosphorus. These deposits occur as crusts on volcanic and other rocks and as nodules on abyssal plain sediment that are typically about 3 to 10 centimeters (1 to 4 inches) in diameter.
How many zones are in the ocean?
five zones The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the …
Where is the pelagic zone?
the open sea The pelagic zone is the part of the open sea or ocean comprising the water column, i.e., all of the sea other than that near the coast or the sea floor. In contrast, the demersal zone comprises the water that is near to (and is significantly affected by) the coast or the sea floor.
What are the 3 parts of the ocean?
The ocean has three main layers: the surface ocean, which is generally warm, and the deep ocean, which is colder and more dense than the surface ocean, and the seafloor sediments. The thermocline separates the surface from the deep ocean. Due to density differences, the surface and deep ocean layers do not easily mix.
What are the 3 levels of the ocean?
The three main layers of the ocean are the epipelagic zone, the mesopelagic zone, and the bathypelagic zone.
