Answer 16

floating algae

Question 17

Profundal zone

a region of water where sunlight does not reach, below the limnetic zone in very deep lakes

Question 18

Benthic zone

Answer 18

the muddy bottom of a lake, pond, or ocean beneath the limnetic and profundal zones

Question 19

Oligotrophic

Answer 19

describes a lake with low level of phytoplankton due to low amounts of nutrients in the water

Question 20

Mesotrophic

Answer 20

describes a lake with a moderate level of fertility

Question 21

Eutrophic

Answer 21

describes a lake with a high level of fertility

Question 22

Freshwater wetland

Answer 22

an aquatic biome that is submerged or saturated by water for at least part of each year, but shallow enough to support emergent vegetation

Question 23

Estuary

Answer 23

an area along the coast where the freshwater of rivers mixes with salt water from the ocean

Question 24

Salt marsh

Answer 24

found along the coast in temperate climates, a marsh containing non-wordy emergent vegetation

Question 25

Mangrove swamp

Answer 25

a swamp that occurs along tropical and subtropical coasts, and contains salt-tolerant trees with roots submerged in water

Question 26

Intertidal zone

Answer 26

the narrow band of coastline that exists between the levels of high tide and low tide

Question 27

Coral reef

Answer 27

represents earth's most diverse marine biome, and are found in warm, shallow waters beyond the shoreline in tropical regions

Question 28

Coral bleaching

Answer 28

a phenomenon in which algae inside corals die, causing the corals to turn white

Question 29

Open ocean

Answer 29

deep ocean water, located away from the shoreline where sunlight can no longer reach the ocean bottom

Question 30

Photic zone

Answer 30

the upper layer of the ocean water in the ocean that receives enough sunlight for photosynthesis

Question 31

Aphotic zone

Answer 31

the deeper layer of ocean water that lacks sufficient sunlight for photosynthesis

Question 32

Chemosynthesis

Answer 32

a process used by some bacteria to generate energy with methane and hydrogen sulfide

Question 33

Leeve

Answer 33

an enlarged bank built up on each side of the river

Question 34

Dikes

Answer 34

structures built to prevent ocean waters from flooding adjacent land

Question 35

Dam

Answer 35

a barrier that runs across a river or stream to control the flow of water

Question 36

Reservoir

Answer 36

the water body created by damming a river or stream

Question 37

Fish ladder

Answer 37

a stair-like structure with water flowing over them, which allows migrating fish to get around a dam

Question 38

Desalination

Answer 38

a process for obtaining freshwater by removing the salt from the saltwater. Also known as desalinization

Question 39

Distillation

Answer 39

a process of desalination in which water is boiled and the resulting steam is captured and condensed to yield pure water

Question 40

Reverse osmosis

Answer 40

a process of desalination in which water is forced through a thin semipermeable membrane at high pressure
