Which of the following combinations of factors BEST explains the absence of major ocean fishing ground around tropical Africa?
Answer Details
The combination of a narrow continental shelf and an unindented coastline BEST explains the absence of major ocean fishing grounds around tropical Africa. A narrow continental shelf means that the shelf drops off steeply into deep water, which limits the availability of fish habitat in the shallower waters near the shore. An unindented coastline means that there are no natural harbors or bays that provide sheltered areas for fish to congregate and spawn. This makes it more difficult for fishermen to access the fish populations that do exist. While factors such as warm ocean currents, poor plankton supply, and pollution of seawater can also affect fish populations, they are not the primary reasons for the absence of major ocean fishing grounds around tropical Africa.
