4. Sonar Sonar is an acronym: Sound Navigation And Ranging.
Sends out a continuous sound waves to the ocean floor they bounce back and the speed that it took for it to return is used to calculate the distance or depth of ocean floor. Similar to the pulse on a slinky

5. The Ocean Basins The Water Planet Exploration of the Ocean
Ocean floor can be divided into two major areas:
Continental margin: shallow parts of the ocean floor that are made of continental crust and a thick wedge of sediment
Deep ocean basin: oceanic crust and a thin sediment layer, deepest part of ocean beyond the continental margin.

6. The Ocean Basins Features of the Ocean Floor Continental Margins
Can be caused by rivers or turbidity currents
Features of the Ocean Floor
Continental Margins
Continental Shelf, Slope and Rise
Boundary between continental crust and oceanic crust
Turbidity currents form when earthquakes cause underwater landslides or when large sediment loads run down a slope.
Accumulation of sediment from turbidity currents

7. Deep Ocean Basin
Broad flat plains, submerged volcanoes, gigantic mountain ranges, and deep trenches
Layers of sediment cover.
Sunken islands that are eroded by waves aka tablemounts
Formed when plates move AWAY from each other. AKA abyssal hills
Submerged volcanic mountains
Earthquakes, volcanic mountain ranges, and volcanic islands form near here

8. The Ocean Basins Ocean Floor Sediments Sources of Deep Ocean Sediments
Inorganic Sediments: non living (rocks etc)
Biogenic Sediments: produced by living organisms. Ex. Silica and calcium carbonate
Chemical Deposits: when substances disolve in ocean water they crystalize. Nodules made of manganese, nickel, copper, and iron do this.

9. The Ocean Basins Ocean Floor Sediments
Physical Classification of Deep ocean floor Sediments
Muds: ocean floor very fine silt and clay sized particles of rock
Ooze: soft fine sediment made mostly of biogenic material
Calcareous ooze: made mostly of calcium carbonate found only in deep cold ocean water.
Siliceous ooze, found at any depth is made mostly of silicon dioxide,
