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
