描述Next to air, water is the most essential of human requirements. The hydrosphere-the waters of the Earth, its oceans, rivers and lakes-is vital, constituting a feature unique in the solar system and one responsible for physical and climatic phenomena characteristic of the planet. Water moves through the hydrologic cycle and runs the heat engine of the Earth, approximately 97% of it occurring in the oceans. These contain vast natural resources including abundant plant and animal life and they assist in cleansing the atmosphere by becoming the final repository of air and land pollutants of which many are man-made. Unfortunately their ability to do this is diminishing because of rising pollution by toxicants such as DDT, nuclear by-products such as strontium-90 and oil spills. The oceans contain huge quantities of various substances mostly originating from the atmosphere, biological activity, river transport after rock weathering, groundwater, spreading zones along mid-oceanic ridges and crustal out-gassing. After hydrogen and oxygen, the commonest elements in them are Cl, Na, Mg, S, K, Ca, Br, C and B. The atmosphere and the oceans together cooperate in an energy cycle important in co

The Hydrologic Cycle,is spread out evenly throughout the year and does not prevent a severe drought arising at least once quinquennially. Many countries are much wetter and often have monsoonal rainfall whereas in other parts of the world extremely dry regimens are to be found. Of course rainfall is only one aspect of a

The Atmosphere,sphere which is probably unique in the solar system because it contains water vapour, most of this being near its saturation point as a result of which cloudless conditions can change rapidly to obscure ones. Atmospheric water amounts to only 0–1% of the total quantity of water on the planetary surf

Rivers,e determination of discharge, the volume of water passing through a given cross-section during a particular time interval. Units of measurement of discharge include cumecs (cubic metres per second) and for small flows litres per second. Earlier measurements may be given in cubic feet per second or c

Lakes and Other Surface Water Manifestations,o the sea or having such access solely by means of rivers. They occupy depressions into the zone of saturation in the environmental soil and rock, derive their water from rain, melted snow, ice, etc. and are small scale agents of erosion in which waves may develop, controlled by the same factors gov

The Oceans,ee Chapter 1, Table 1.10). This table also gives the volume of the oceans as l.37×l0.km. and since the rate of supply of water by rivers is approximately 36 × 10.g/year (or, as the density of water is about 1, 36 × 10. ml/year or 36 × 10.km. annually) the theoretical time interval required for ‘fill

The Hydrologic Cycle, by the sun which gives rise to evaporation. A humid mass of air is created above the water surface and, becoming further warmed by it, ascends into the atmosphere due to its being lighter than the overlying cold air. The study of water and its various modes of occurrence on and in the planet constitutes the science of hydrology.
