Question 5

Southern ocean

Answer 5

Question 6

Salinity

Answer 6

Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water.

Question 7

surface zone

Answer 7

Aptly named for its position at the surface level, this sunlight zone, also called the surface zone or epipelagic zone, extends downward 200 meters or roughly 5% of the ocean’s average depth.

Question 8

Thermocline

Answer 8

A thermocline A distinct layer based on temperature within a large body of fluid A gradiant of distinct temperature differences associated with depth.

Question 9

deep zone

Answer 9

The hadal zone (named after the realm of Hades, the underworld in Greek mythology), also known as the hadopelagic zone, is the deepest region of the ocean lying within oceanic trenches. The hadal zone is found from a depth of around 6,000 to 11,000 meters (20,000 to 36,000 feet).

Question 10

Evaporation

Answer 10

the process of turning from liquid into vapor

Question 11

Condensation

Answer 11

Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization.

Question 12

Precipitation

Answer 12

In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds.

Question 13

continental shelf

Answer 13

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

Question 14

continental slope

Answer 14

A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters.

Question 15

continental rise

Answer 15

The continental rise is a low-relief zone of accumulated sediments that lies between the continental slope and the abyssal plain.

Question 16

abyssal plain

Answer 16

An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres and 6,000 metres.

Question 17

mid-ocean ridge

Answer 17

A mid-ocean ridge is a seafloor mountain system formed by plate tectonics.

Question 18

rift valley

Answer 18

A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift.

Question 19

Seamount

Answer 19

A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water’s surface, and thus is not an island, islet or cliff-rock.

Question 20

ocean trench

Answer 20

Oceanic trenches are prominent, long, narrow topographic depressions of the ocean floor.

Question 21

Plankton

Answer 21

Plankton are the diverse collection of organisms found in water that are unable to propel themselves against a current. The individual organisms constituting plankton are called plankters.

Question 22

Nekton

Answer 22

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

Question 23

Benthos

Answer 23

Benthos, also known as benthon, is the community of organisms that live on, in, or near the bottom of a sea, river, lake, or stream, also known as the benthic zone.

Question 24

desalination

Answer 24

Desalination is a process that takes away mineral components from saline water.
