Answer 22

Thermocline

Question 23

A vertical zone in the oceanic water column in which salinity changes rapidly with depth.

Answer 23

Halocline

Question 24

A layer in an ocean or other body of water in which water density increases rapidly with depth.

Answer 24

Pycnocline

Question 25

Type of organism that can withstand only a small range of temperature.

Stenothermic organisms

Question 26

Type of organisms who can survive in a wide range of temperatures.

Answer 26

Eurythermic organisms

Question 27

Organisms who have the ability to regulate their own body temperature regardless of
the temperature of the water environment = warm blooded animals

What is an absolute scale of temperature?

Answer 28

Kelvin Scale

Question 29

Type of organism that accommodate small changes in salinity.

Answer 29

Stenohaline organisms

Question 30

Organisms that accommodate large changes in salinity. Not necessarily mean it can live from 0 ppt (usually 20 ppt); needs acclimatization.

Answer 30

Euryhaline organisms

Question 31

It is the unit of measurement for salinity equivalent to g/L.

Answer 31

Parts per thousand (ppt)

Question 32

It is present at any depth in the water that is equivalent to the weight of the atmosphere and the weight of the water column. The weight of the water column is equivalent to one atmosphere for each 10-meter increase in depth.

Answer 32

Pressure

Question 33

True or False: water pressure is greater than atmospheric pressure because it is denser; it is acted upon by hydrostatic pressure.

Answer 33

True
