Critical Analysis Question:
According to the United Nations Food and Agriculture Organization, the people in the nations on the west coast of Africa consumed much more fish per capita than did the people in the nations along the east coast of Africa. Can you explain this difference in terms of availability?
To formulate your answer, first consider these additional thought questions:
Which of the following occur where there is coastal upwelling? Select all that apply. | |
nbIRnRe8R9/OaJB+ | Warm surface water is blown away from the coast, and cold water from the depth rises along the coast to fill the void. |
xdqz80TY1Vwhogjf | Strong winds drive against the coastline, creating waves much higher than normal. |
nbIRnRe8R9/OaJB+ | Water that is rich in nutrients rises to the surface. |
xdqz80TY1Vwhogjf | Solar rays become much more intense, heating the surface water to temperatures much higher than normal. |
You now understand that phytoplankton makes up the base of the marine food chain and that their populations can increase when nutrient-rich waters, occurring from upwelling events along coastlines, are present. Now look at the map.
