Homework: Sketches and explanations
Read the question carefully and then compose your answer. Be concise and complete.
A. Why does upwelling promote biological productivity more than downwelling?
B. Suppose that a shoreline lying in the northern hemisphere and running in an east-west direction experiences a wind coming from the west. Assume that the water lies to the north of the shoreline. Sketch this situation and discuss whether or not it is likely to promote high biological productivity.
C. Explain with a sketch how the trade winds and westerlies dictate the level of biological productivity in equatorial regions versus subtropical gyres. Include both northern and southern hemispheres in your sketch and explanation.
D. In high-latitude regions, is biological productivity higher in the summer or in the winter? Why?
E. Why do most fish have shiny undersides and dark-colored upper bodies? What is the term for this type of adaptation?
F. Explain why it is a more efficient use of the ocean's resources to eat sardines than tuna.
G. Explain how the evolutionary need to overcome the three types of drag experienced by swimmers leads to the shapes seen in most fish.
H. What instrument is used to make global maps of sea level rise? How does this instrument work? What are the two main causes of sea level rise? Explain how the instruments used to monitor these two causes work.
