Ocean Floor Features
2
What you need to know You need to know where and what the Deep Ocean basin, continental margin, shelf, slope, and rise, shoreline, abyssal plain, seamount, guyot, trench, and a mid- Atlantic ridge are.
3
The Continental Slope, Shelf, Rise, and Margin Continental Shelf -Relatively flat part of a continental margin that is covered by shallow ocean water. Continental Slope -Part of the continental margin at the edge of a continental shelf where the ocean plunges steeply at 4 to 5 kilometers. Continental Rise - Part of a continental margin that separates a continental slope and the ocean floor. Continental Margin-Area where underwater edge of a continent meets the ocean floor.
4
Shoreline, Deep Ocean Basin, and Abyssal Plain. Shoreline-Boundary where the land and the sea meet Deep Ocean Basin-Oceanic Crust/Abyssal Plain Abyssal Plain-Large flat area on the ocean floor.
5
Active Vs. Passive Continental Margins Active Margins-Commonly the sites of earthquakes, volcanoes, mountain building, and the formation of new igneous rock. Passive Margins- Flat land extending both directions from the beach, long river systems, and the accumulation of thick piles of sedimentary debris on the relatively wide continental shelves.
