Which of these is NOT a division of the Ocean Floors?

The correct answer is The Continental Deeps.

Key Points

• The ocean floors can be divided into four major divisions -
  • The Continental Shelf
  • The Continental Slope
  • The Deep Sea Plain
  • The Oceanic Deeps
• Thus, 'the continental deeps' isn't one of them, making option 2 the right answer.

Additional Information

• A continental shelf is the edge of a continent that lies under the ocean.
• A continental slope is a slope seaward from the shelf to the upper edge of a continental rise or the point where there is a general reduction of the slope.
• A deep sea plain or an abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 meters and 6,000 meters.
• Oceanic deeps are the deepest parts of the oceans covered with fine-grained sediments like clay and silt.
