Question 12

Condensation

Answer 12

water which collects as droplets on a cold surface when humid air is in contact with it.

Question 13

Precipitation

Answer 13

any product of the condensation of atmospheric water vapor that falls under gravity from clouds.

Question 14

continental shelf

Answer 14

a portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea.

Question 15

continental slope

Answer 15

the slope between the outer edge of the continental shelf and the deep ocean floor

an underwater plain on the deep ocean floor usually found at depths between 3,000 meters and 6,000 meters.

Question 18

mid-ocean ridge

Answer 18

a seafloor mountain system formed by plate tectonics. It typically has a depth of 2,600 meters and rises about two kilometers above the deepest portion of an ocean basin.

Question 19

rift valley

Answer 19

a large elongated depression with steep walls formed by the downward displacement of a block of the earth’s surface between nearly parallel faults or fault systems.

Question 20

Question 21

ocean trench

Answer 21

topographic depressions of the seafloor, relatively narrow in width, but very long. These oceanographic features are the deepest parts of the ocean floor.

Answer 22

the diverse collection of organisms that live in large bodies of water and are unable to swim against a current.

Question 23

Nekton

Answer 23

Nekton or necton refers to the aggregate of actively swimming aquatic organisms in a body of water.

Question 24

Benthos

Answer 24

the community of organisms that live on, in, or near the seabed, river, lake, or stream bottom

Question 25

desalination

Answer 25
