Continental shelf	- The width varies around the edges of the continents. In some places it is fairly shallow and in other place it becomes very deep, but it is not the deepest part of the ocean.
Continental slope	The steep slope where the continental shelf drops to the bottom of the ocean floor.The depth of the ocean water increases greatly here.
Mid-ocean ridge	On the bottom of the ocean, there is a central ridge, or mountain range, that divides the ocean floor into two parts.
Rift zone	In the center of the highest part of the mid-ocean ridge is a narrow trench called a rift.  Underwater volcanic activity that adds mountains to either side of the mid-ocean ridge occurs here.
Trenches	 the deepest part of the ocean basin and are deeper than any valley found on land.
