What is the source of heat in the upper level of the ocean?
At what depth is the temperature change the most dramatic?
Explain why the temperature varies in the above example.
Why is there such a small change after 500 meters?
What is the thermocline?
Label the thermocline.
How does the thermocline vary in the tropics versus the higher latitudes?
How will the seasons affect the thermocline?
What causes upwelling and how might an upwelling affect the thermocline in a local area?
Using your textbook (page 164), draw a T-chart to compare the thermal inertia of the land
versus the ocean.
11. Explain the difference in the thermal inertia of land versus the ocean.
12. Write a mathematical statement of the relationship between depth and the temperature in the
ocean.
13. How do marine organisms adapt to the temperature profile?

Explain the three ways in which light is modified when it strikes the ocean’s surface?
How is the photic zone formed?
What is depth of the photic zone?
What happens to light energy when it is absorbed?
Compare the transmission of short wave lengths versus long wavelengths in the ocean.
What conditions in the ocean cause light penetration to vary slightly for each color?
What types of organisms live in the aphotic zone?
A scuba diver sees a red snapper fish at a depth of 65 meters, what color is it?
Write a mathematical statement that explains the relationship between depth and light
absorption in the ocean.
Research vertical migration in the ocean and explain how marine organisms use this
adaptation to survive.
What is similar about the two graphs?
What is different about the two graphs?
Why is the ocean blue?
