Convergent oceanic-continental boundary
As odd as it is to think of things this way, continental lithosphere is more buoyant than oceanic lithosphere. The oceanic lithosphere is more dense.
the thickest accumulation of sediment on the ocean floor is at the CONTINENTAL SLOPES AND RISES. :)

The portion of a continent that is submerged beneath the ocean is called the Continental Shelf.
The portion of a continent that is submerged beneath the ocean is called a continental shelf. It extends from the shoreline to a point where there is a steep drop-off into the ocean depths.
Continental shelf
The layer beneath the lithosphere is much softer and flows very slowly.
The term for the part of a continent that extends beyond the shoreline beneath relatively shallow seawater is the continental shelf. It is an underwater extension of the continent that slopes gently from the shore to the ocean depths.
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.

Asthenosphere is directly before the lithosphere.
