Which relatively flat feature of the ocean floor is in the open ocean and borders the continental shell?

[Abyssal plains]

Why: Abyssal plains are flat wide areas of the ocean floor. You can find these features in between a continental rise and a mid-oceanic ridge. These plains are covered in sediment and are found deep down, on the ocean floor.
