  3. Continental shelf • A gently sloping, shallow area of a continent or large island.

  4. Continental slope • A steep incline of the ocean floor leading down from the edge of the continental shelf

  5. Abyssal plain • A smooth, nearly flat region of the deep ocean floor.

  6. Mid-ocean ridge • An undersea mountain chain where new ocean floor is produced

  7. trench • A deep, deep-sided canyon in the ocean floor

  8. Intertidal zone • An area that stretches from the highest high-tide line on land out to the point on the continental shelf exposed by the lowest low tide.
