1. What is topography of the ocean?  1. Topography-the surface features of the ocean floor.

2. Features A. Continental Shelf -Slopes gently down from the edge of a continent

b. Continental Slope b. Continental Slope  Slopes steeply from the continental shelf

 It is the base of the continental slope and is made of large piles of sediment. C. Continental Rise

D. Submarine Canyon  Steep V shaped canyon that cuts through the continental shelf and continental slope

E. Abyssal Plain  Flat ocean bottom covered with mud and the remains of marine organisms

F. 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.

G. Guyot G. Guyot  Flat topped seamount flattened by the action of waves

H. Mid-Ocean Ridge H. Mid-Ocean Ridge  Longest Undersea mountain range  Occurs at divergent boundaries

Oceanic Ridges

I. Rift Valley I. Rift Valley  Deep valley that forms between the mountains of a mid-ocean ridge

J. Trench  Steep sided narrow cut in the sea floor  Deepest part of the ocean (Mariana Trench)  Formed from convergent plate boundaries
