Question

2. The unique properties of sea water which include its heat capacity, lower Ereezing point, slower evaporative rate and salinity affect on osmotic pressures are collectively called 3. True/False: The source of the oceans salt is primarily attributable to contributions of ions from the land and its rivers . Arctic waters are supersaturated with dissolved oxygen primarily because of (a) the N to 0 ratio in these waters, (b) seawaters pH range, (c) the colder aters hold more dissolved gases, or (d) Arctic plants require more CO2 than temporate plants In the hydrologic cycle, all of the following are most important EXCEPT (a) hydroscopic nuclei, (b) evapotranspiration from plant surfaces, (c) waters adhesive forces and surface land and groundwater infiltration. 5. tension characteristics, or (d) runoff from the 6. The four main sources of heat to the oceans on earth are and he intensity of the earth's reflectivity of solar incidence is called the 7. T earths 8. Light penetration in seawater is only to a specific depth, therefor 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 at mospheric circulation cells called Hadley Cells, (b) axis of inclination cells, (c) Anti-coriolis cells, or (d) the doldrums. (a) 10. True/False: The Horse Latitudes and the Trade Winds are named after the specific w ind patterns resulting at their particular locations on the earth.

Explanation / Answer

2. Thermophysical properties

3. True

4. Colder water holds more gases

The amount of dissolved oxygen that the water can hold depends on the temperature and salinity of the water. Cold water can hold more dissolved oxygen than warm water and fresh water can hold more dissolved oxygen than salt water. So the warmer and saltier the water, the less dissolved oxygen there can be.

(eg: Cold Coke can hold CO2 better than warmer Coke)

5. Water's adhesive forces and surface tension characteristics.

7. Albedo. The proportion of the incident light or radiation that is reflected by a surface

8. Aphotic zone

The depth beyond which the light penetration is less than 1% is called Aphotic zone.

9. Hadley Cells

The Warm air rises from the Equator and forms a low pressure zone and at approximately 30° latitude becomes dense enough to sink toward the surface forming a high pressure zone. This is also called Horse latitude. This forms a cycle where the warm air rises from the equator and sinks down at 30° and back to the equator.

10. True

The horse latitudes are located at about 30 degrees north and south of the equator. It is common in this region of the subtropics for winds to diverge and either flow toward the poles (known as the prevailing westerlies) or toward the equator (known as the trade winds). These diverging winds are the result of an area of high pressure, which is characterized by calm winds, sunny skies, and little or no precipitation.
