The Earth From classical times it has been known that the earth is roughly spherical in shape. Actually the planet is shaped more like a slightly flattened ball whose polar radius is about 21km shorter than its equatorial radius. The average radius is 6371km. The earth’s specific gravity is 5.5. It is 5.5 times as heavy as an equal volume of water. The specific gravity is greater than that of any other planet in the solar system, but not appreciably different from that of Mercury, Venus and Mars. Because the average specific gravity of surface rocks is only about 2.7, the material existing deep within the earth must have a specific gravity well in excess of the 5.5 average. Very likely, the material at the earth’s center has a specific gravity as high as about 15. The splendid photographs of the earth taken from space by Apollo astronauts remind us that our planet is more than a rocky globe orbiting the sun. The patterns of white clouds above the azure blue color tell us of the presence of an atmosphere and hydrosphere. Here and there one can even discern patches of tan that indicates the existence of continents. Greenish hues provide evidence of the planet’s most remarkable feature: there is life on earth. THE A TMOSPHERE We live beneath a thin but vital envelope of gases called atmosphere. We refer to these gases as air. “Pure air”is composed mainly of nitrogen (78.03%) and oxygen 920.99%). The remaining 0.98% of air is made of argon, carbon dioxide and minute quantities of other gases. One of these “other”components found mostly in the upper atmosphere is a form of oxygen called ozone. Ozone absorbs much of the sun’s lethal ultraviolet radiation, and is thus of critical importance organisms on the surface of the earth. Air also contains from 0.1 percent to 5.0 percent of water vapor. However, because this moisture content is so variable, it is not usually included in lists of atmospheric components. Every day, the atmosphere receives radiation from the sun. This solar radiation provides the energy that heats the atmosphere and drives the winds. Distribution of solar radiation is one of the most important factors in determining the various kinds of climate we experience on the earth. THE HYDROSPHERE（水圈） The discontinuous envelope of water that covers 71 percent of earth’s surface is called hydrosphere. It includes the ocean as well as water vapor. The water contained in streams and lakes, water frozen in glaciers, and water that occurs underground in the pores and cavities of rocks. If surface irregularities such as continents and deep oceanic basins and trenches were smoothed out, water would completely cover the earth to a depth of more than two kilometers. Water is an exceedingly important geologic agent. Glacier composed of water in its solid form alter the shape of the land by scouring, transporting and depositing rock debris. Because water has the property of dissolving many natural compounds, it contributes significantly to the decomposition of rocks and, therefore, to the development of soils on which we depend for food. Water moving relentlessly down hill as sheetwash, in rills, and in streams loosens and carries away the particles of rock to lower elevations where they are deposited as layers of sediment. Clearly, the process of sculpturing our landscapes is primarily dependent upon water. By far the greatest part of the hydrosphere is contained within the ocean basins. These basins are of enormous interest to geologists who have discovered that they are not permanent and immobile as once believed, but rather are dynamic and ever changing. There is ample evidence
