The area where edges of continents meet the ocean

• continental shelf

• continental margin

• abyssal plain

• seamount

The shallowest part of a continental margin extending seaward from the shore

• deep sea trench

• turbidity current

sloping oceanic region found beyond the continental shelf that generally marks the edge of the continental crust and may be cut by sub-marine canyons
