Question 6

The concentration of dissolved salts in water

Answer 6

Question 7

Often this layer is referred to as the mixed layer because this is where winds and waves stir up the water. This layer is highly influenced by solar energy, heating up the water. The temperature is roughly that of the air above it.

Answer 7

Surface Zone

Question 8

A layer of water located between the surface and deep water layers that rapidly decreases in temperature as depth increases.

Answer 8

Thermocline

Question 9

The layer of water below the thermocline that slowly decreases in temperature as depth increases.

Answer 9

Deep Zone

Question 10

Cycle of processes (Evaporation, Condensation, Precipitaion, Run-Off)

Answer 10

Water Cycle

Question 11

liquid to gas process

Answer 11

Evaporation

Question 12

gas to liquid process

Answer 12

Condensation

Question 13

water released from clouds in the form of rain, snow, sleet, or hail

Answer 13

Precipitation

Question 14

the area of seabed around a large landmass where the sea is relatively shallow compared with the open ocean

Answer 14

Continental Shelf

Question 15

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

Answer 15

Continental Slope

Question 16

the imaginary geographic line defined by the fact that water poured on one side of it would ultimately flow into the ocean on one side of a continent same with the other side

Answer 16

Continental Divide

Question 17

underwater plain on the deep ocean floor

Answer 17

Abyssal Plain

Question 18

a long, (seismically active) submarine ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading. An example is the Mid-Atlantic Ridge.

Answer 18

Mid-Ocean Ridge

Question 19

A long, narrow valley lying between two normal geologic faults

Answer 19

Rift Valley

Question 20

A large underwater mountain, usually conical in shape

Answer 20

Seamount

Question 21

hemispheric-scale long but narrow topographic depressions of the sea floor

Answer 21

Ocean Trench

Question 23

The collection of marine and freshwater organisms that can swim freely and are generally independent of currents, ranging in size from microscopic organisms to whales

Answer 23

Nekton

Question 24

the flora and fauna found on the bottom, or in the bottom sediments, of a sea, lake, or other body of water

Answer 24

Benthos

Question 25

process that extracts mineral components from saline water (removal of salts and minerals from a target substance)

Answer 25

Desalination
