Question
. True/False: Fresh waters molecular polarity contributes to its being called the universal solvent 2. The unique properties of sea water which include its heat capacit freezing point, slower evaporative rate and salinity affect on osmotic pressures are collectively called y, lower 3. True/False: The source of the oceans salt is primarily attributable to contributions of ions from the land and its rivers 4. Arctic waters are supersaturated with dissolved oxygen primarily because of (a) the N to O ratio in these waters, (b) seawaters pH range, (c) the colde waters hold more dissolved gases, or (d) Arctic plants require more C02 than temporate plants 5. In the hydrologic cycle, all of the folloving are most important EXCEPT (a) hydroscopic nuclei, (b) evapotranspiration from plant surfaces, (c) waters adhesive forces and surface tension characteristics, or (d) runoff from the land and groundwater infiltration. 6. The four main sources of heat to the oceans on earth are , and 7. The intensity of the earth's reflectivity of solar incidence is called the earths . Light penetration in seawater is only to a specific depth, therefore determining availability of light for photosynthesis. This depth is called the (a) aphotic zone (b) photolytic zone (c) reflective compensation zone, or (d) the pycnocline. 9. Warm air rises at the equator and falls to earth at the poles yet is reflected right in the Northern Hemisphere and left in the Southern Hemisphere. The combination of the coriolis, gravitational and density affects all contribute to the formation of atmospheric circulation cells called (a) Hadley Cells, (b) axis of inclination cells, (c) Anti-coriolis cells, or (d) the doldrums. 10. True/False: The Horse Latitudes and the Trade Winds are named after the specific wind patterns resulting at their particular locations on the earth.Explanation / Answer
Answer :
1. True.
Fresh water is a solution that contains dissolved minerals and gases. So many substances dissolved in water that it has been called "the universalsolvent". Water molecules have a polar arrangement of the oxygen and hydrogen atoms-one side has a positive electrical charge and other side has a negative electric charge. This aloows the water molecule to becomr attracted to maany other different types of molecules.
