Presentation transcript:

1) What is topography of the ocean? The surface features of the ocean floor.

2) What is the Continental Shelf? Slopes gently down from the edge of a continent.

Continental Shelf Continental Shelf

3) What is the Continental Slope? Slopes steeply from the continental shelf

Continental Shelf Continental Shelf Continental Slope

4) What is the Continental Rise? The base of the continental slope - made of large piles of sediment.

Continental Shelf Continental Shelf Continental Rise Continental Slope

5) What is a Submarine Canyon? Steep V shaped canyon that cuts through the continental shelf and continental slope

Continental Shelf Continental Shelf Submarine Canyon Continental Rise Continental Slope

6) What is an Abyssal Plain? Flat ocean bottom covered with mud and the remains of marine organisms

Continental Shelf Continental Shelf Submarine Canyon Abyssal Plain Continental Rise Continental Slope

7) What is a Seamount? Steep-walled, pointy, extinct volcano The seamount’s shown here can reach up to just under 600 ft. of the surface. They are located off the coast of Alaska.

8) What is a Guyot? Flat topped seamount - flattened by the action of waves

10) What is a Rift Valley? Deep valley that forms between the mountains of a mid-ocean ridge

11) What is a Trench? Steep sided narrow cut in the sea floor Deepest part of the ocean (Mariana Trench) Formed from convergent plate boundaries
