Answer 18

floating algae

Question 19

Profundal zone

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

Question 20

Benthic zone

Answer 20

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

Question 21

Oligotrophic

Answer 21

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

Question 22

Mesotrophic

Answer 22

describes a lake with a moderate level of fertility

Question 23

Eutrophic

Answer 23

describes a lake with a high level of fertility

Question 24

Freshwater wetland

Answer 24

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 25

Estuary

Answer 25

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

Question 26

Salt marsh

Answer 26

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

Question 27

Mangrove swamp

Answer 27

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

Question 28

Intertidal zone

Answer 28

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

Question 29

Coral reef

Answer 29

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

Question 30

Coral bleaching

Answer 30

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

Question 31

Open ocean

Answer 31

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

Question 32

Photic zone

Answer 32

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

Question 33

Aphotic zone

Answer 33

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

Question 34

Chemosynthesis

Answer 34

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

Question 35

Leeve

Answer 35

an enlarged bank built up on each side of the river

Question 36

Dikes

Answer 36

structures built to prevent ocean waters from flooding adjacent land

Question 37

Dam

Answer 37

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

Question 38

Reservoir

Answer 38

the water body created by damming a river or stream

Question 39

Fish ladder

Answer 39

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

Question 40

Desalination

Answer 40

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

Question 41

Distillation

Answer 41

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

Question 42

Reverse osmosis

Answer 42

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