water vocab

4. the deepest parts of the ocean. The deepest one is the Marianas Trench (located in the S. Pacific Ocean - almost 5 miles deep)
5. 1000 to 4000m; higher pressure, dense water, cold, fewer animals, no light
7. a process used by some bacteria in the ocean to generate energy with methane and hydrogen sulfide
9. a chain of undersea mountains that circles the Earth through every ocean
11. the amount of dissolved salts in seawater
12. having light; darkness
14. the steep incline between the continental shelf and the abyssal plain; also thought of as the "true" edge of the continent
15. 4000 to 6000 m; no light; crushing pressure, very cold and salty; few animals; sea cucumber and tube worms
16. zone the area that lies between the low-tide and the high-tide line
18. the production of non-thermal light by creatures converting chemical energy to light energy to lure prey, attract a mate, or assist in keeping a species together. ~75% of creatures glow.
20. extends from the edge of the continent outward to where the bottom sharply drops off into a steep slope
21. having light
22. extends past the sunlight zone
23. organisms that live on, near or in the ocean floor
25. the movement of cold water upward from the deep ocean that is caused by wind. This brings up tiny organisms, minerals & nutrients to come from deepest parts of ocean

1. the study and exploration of the world's oceans
2. the first 200m of ocean water that extends outward from shore and covers most of the continental shelf; warm, much light, diverse with plants and animals
3. free-swimming organisms move all through the water column and are independent of the tides, currents and waves
6. animal-like component of plankton that feed on plankton and other zooplankton (primary consumers) (think ANIMALS belong in a ZOO)
8. an opening in the sea floor where super-heated water, gases, and other nutrients are released into the surrounding seawater
10. extends from 6000m deep to the bottom of the ocean; very few animals; temperature near freezing; high pressure
13. body of water where fresh water meets saltwater
17. 200 to 1000m; dim light, denser water, more pressure
19. tiny algae and plants that float in water and are carried by waves and currents. They MAKE their own food. Phyto (think PHOTOSYNTHESIS)
24. sound NAvigation Ranging - used to measure ocean depth by sending sound to bounce off the ocean floor
