1. The Ocean Floor

2. The Ocean Floor Divided into two parts:
Continental margin
Deep Ocean Basin
Continental crust comprises continental margin
Deep ocean basin is comprised of oceanic crust

3. Continental Margin Continental Shelf
Begins at shoreline and ends at the slope
Depth can reach up to 200 M
Continental Slope
Begins at shelf and extends to ocean floor
Ranges from 200 to 4,000 M

4. Deep-ocean Basin Abyssal Plain
Broad flat portion of the ocean floor
Average depth is 4,000
Deepest point in the ocean is the Mariana Trench located in the Pacific ocean: 11,033 meters
Ridges and rift valleys formed at divergent boundaries
Trenches formed at convergent boundaries
