Question

Compare Figure 4a-2, depicting means annual salinity, with figure 4a-1, displaying average annual E-P values. This comparision shows that, in general, region of ocean with higher surface salinities are associated with areas where___.

a. E>P

b. E=P

c. E<P

Freshwater Flux between Ocean and Atmosphere
Figure 4A-1 is the climatological annual mean freshwater flux, or global
distribution of evaporation (E) minus precipitation (P), or E – P in millimeter per
day (mm/d) over ocean areas. The figure is from the Committee on Earth
Observation satellites (2009) via NASA.

Evaporation and precipitation have a considerable effect on surface ocean salinity.
Figure 4A-2 is a global map of annual mean salinity. (This same figure appears in
Investigation 3A.) Mentally mark each major center of highest salinity with an “H"
and survey the map to identify regions of relatively low salinity.

Expert Solution

Step 1

Salinity is defined as the function amount of dissolved materials in the water. In other words, it is the total amount of solid material dissolved in water including dissolved gases excluding the dissolved organic substance. The salinity of the seawater varies from place to place depending on the rate of evaporation, precipitation, amount of fresh water supply etc.
