Here's a breakdown:

* Continental Shelf: This is the gently sloping, submerged area that extends from the shoreline to the point where the slope becomes steeper. It's like a submerged plateau around the continent.

* Continental Slope: This is the steeper slope that connects the continental shelf to the deep ocean floor.

* Continental Rise: This is the gently sloping area at the base of the continental slope. It's made up of sediment that has been washed off the continent.

So, the continental shelf is the underwater part of the continent that is directly connected to the landmass.
