  • Underwater mountain range- formed by sea floor
    spreading

7
Abyssal Plain

8
Guyot
  • Flat topped sea mount

9
Seamount
  • Underwater mountain

10
Ocean Trench
  • Deep canyon

11
Sonar
  • Sound navigation and ranging- uses sound to
    calculate distance

12
Intertidal Zone
  • Between high and low tides. Changes in salinity,
    temperature, underwater exposed to air

13
Neritic Zone
  • From low tide to the end of the continental
    shelf. Shallow, lots of sunlight

14
Open Ocean
  • Water beyond the edge of the continental shelf

15
Plankton
  • Tiny algae animals that float in the water (ex-
    diatoms)

16
Nekton
  • Free swimming animals that can move about (ex-

Food Web
  • All of the relationships that exist in a habitat

20
Estuary
  • Coastal inlets where water from rivers (fresh)
    mixes with salty ocean water--- brackish (partly
    fresh, partly salty)

21
Atoll
  • Ring shaped coral reef surrounding a lagoon

22
Bioluminescence
  • Production of light by living things

23
Hydrothermal Vent
  • Hot water rises out of the cracks in the ocean
    floor is heated by the underlying magma

24
Aquaculture
  • The farming of saltwater and freshwater organisms

25
