The table below shows surface sea water properties observed at regions, "A", "B" and "C". Which statements given below are correct? (More than one correct answer.) (Assume that surface salinity can be affected by evaporation and precipitation only. Region Salinity (g/kg) Density (kg/m3) A (a) 36.0 1027 B 12 35.5 1027 C 12 34.0 (b) The temperature of region is less than 12 “A” The density of region is between 1000 and 1027 kg/m3. “C” The value of 'evaporation minus precipitation' at region is higher than those at regions “A” and region “B” “C”. If we sample equal volumes of water from and and mix them (assuming they are “A” “B” maintained at their original temperature), water density will increase. Global warming can be caused by an ________: 15. (several correct answers.) Increased rate of thermonuclear fusion in the Sun. Increased greenhouse gases in the Earth’s atmosphere. Increased atmospheric humidity. Increased sulphate aerosols in the atmosphere. 16. Oceanic regions of both the hemispheres lying in the same latitude as the desert belts are characterized by _________________. (More than one correct answer.)
