Answer the following question.
Explain the distribution of salinity around the Tropic of Cancer and tropic of Capricorn.
The Tropic of Cancer is the circle marking the latitude 23.5 degrees north, where the sun is directly overhead at noon on June 21, the beginning of summer in the northern hemisphere. The Tropic of Capricorn is the circle marking the latitude 23.5 degrees south where the sun is directly overhead at noon on December 21, the beginning of winter in the northern hemisphere. Ocean salinity is on average 35 ppt, but can range anywhere from 33-38 ppt depending on the processes affecting it (like precipitation and evaporation). Surface salinity can even reach as high as 40 ppt in areas like the Red Sea, which is in a high evaporation latitude.
