Continental Margin
the zone of the ocean floor that separates the thin
oceanic crust from thick continental crust.

Continental shelf
the extended perimeter of each continent and associated
coastal plain
continental slope
The continental shelf is where the shallow waters of the ocean meet the shore.
Farther out, the water gets progressively deeper, and this is the continental slope
submarine canyon
a steep-sided valley cut into the sea floor of the
continental slope, sometimes extending well onto the continental shelf

oceanography-
is a science that draws on the methods and knowledge of geology, chemistry, physics, and biology to study all aspects of the world ocean.

bathmetry-
the measurement of ocean depths and the charting of the shape or topography of the ocean floor

sonar-
allows scientists to study the ocean floor in a more efficient and precise manner than ever before.

is the area of the deep-ocean floor between the continental margin and the oceanic ridge

abyssal plain-
is a very level area of the deep-ocean floor, usually lying at the foot of the continental rise.

seamounts-
seamount is an isolated volcanic peak that rises at least 1000 meters above the deep-ocean floor, and a guyot is an eroded, submerged seamount.
