Continental Margins • Shallower portions of the ocean floor • Is the boundary between the ocean floor and the continents
Continental Shelf • Edge of the continent that is covered by ocean water • Varies in width • Effected by sea level
Continental Slope • Steep incline at the edge of the continental shelf • Features that are found on the shelf • Canyons • Turbidity currents – currents that carry sediments and cause more sloping • Continental rise – raised edge at the base
Deep Ocean Basin • Ocean Floor – oceanic crust
Trenches • Deep valley in the ocean basin • Caused by tectonic features • Deepest part on the ocean
Abyssal Plains • Flat floor in the ocean
Mid-Ocean Ridges • Underwater mountain chain • New seafloor is created here • Because of the making of new crust, the crust breaks into series of faults called Fracture Zones
Seamounts • Isolated volcanic mountain • If they rise above the ocean surface it forms an island (Hawaii)
Guyots • Old seamounts that have sunk beneath the ocean surface http://www.coast-nopp.org/visualization_modules/physical_chemical/basin_coastal_morphology/principal_features/deep_ocean/seamounts/seamounts.html
submersible • Underwater Research Vessel
the Hard Suit 2000. • A new suit that lets divers diver deeper, faster and stay longer
Sonar • Sonar is a device that is used to detect objects through sound waves.
