Answer to Question 1

ANS: C
The pycnocline zone has a direct relationship between density and depth. This means as the depth
increases in the water column, the density also increases. This is mainly the effect of rapidly
decreasing water temperatures. Information can be found in the section The Ocean Is Stratified by
Density.



Answer to Question 2

ANS: B
Water has high thermal inertia. It resists large changes in temperature despite the addition or removal
of large amounts of heat energy. Information can be found in the section Surface Water Moderates
Global Temperature.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
