Although the equatorial regions have the highest annual average temperatures, the salinity in the oceans is highest near the tropics because: 1. equatorial areas receive heavy rainfall 2. salinity is not affected by temperature 3. equatorial oceans experience a lot of turbulenees 4. high relative humidity in equatorial areas checks evaporation

Answer: Option A

Although the equatorial regions have the highest annual average temperatures, the salinity in the oceans is highest near the tropics because equatorial areas receive heavy rainfall, salinity is not affected by temperature and high relative humidity in equatorial areas checks evaporation
