Earth's Dynamic Ocean & Atmosphere - Essay Example This refers to the deflection of circulating air due to the earth’s rotation (Mathez & Webster, 2004). This deflection causes the air to rotate to the right in the northern hemisphere and to the left in southern hemisphere. 1. During the development of tides, the moon offers a gravitational pull on the earth which causes the ocean to bulge (Mathez & Webster, 2004). The sun also offers gravitational force that causes tides. Inertia causes a centrifugal force that causes the ocean to bulge; hence the ocean bulges twice. 2. Variations in tidal ranges are caused by the distance and direction of the sun and the moon. Spring tides have the greater rangers which occur when the sun and the moon align themselves in a syzygy position (Mathez & Webster, 2004). One of the methods of preventing loss of property by erosion is preservation and imitation of nature whereby plants by the seashores are preserved to prevent erosion. The roots bind the earth together while the branches prevent erosion by rain. Another method is keeping the slopes gentle. This absorbs wave energy; hence prevents erosion by waves. The three cells involved in atmospheric circulation are: Hadley, Polar and Ferrel. Circulation of the Hadley cell results in two pressure belts: high pressure (subtropical ridge) and low pressure (near equatorial trough). The polar cell causes cold dense air at the pole which leads to high pressure and subsidence (Mathez & Webster, 2004). Lastly, the Ferrel cell causes a westerly flow which causes a strong downward vertical
