OCEANS: ItsImpact to Weather &BiodiversityBy: Sushmita A. Zamora
great body of salt water comprising all the oceansand seas that cover nearly three-fourths of thesurface of the earth.The world ocean covers 71 percent of the earth’ssurface, or about 361 million sq km (140 million sqmi). Its average depth is 5,000 m (16,000 ft), and itstotal volume is about 1,347,000,000 cu km(322,300,000 cu miOceans

The ocean regulates the hydrologic or water cycle - Sincethis comprises ¾ of the earth’s surface, most amount ofwater vapor came from the oceans. The changes in oceancurrent may result to weather changes in land.The ocean serves as intermediary of the winds which helpto circulate air- The surface currents of the ocean arecharacterized by large gyres, or currents that are kept inmotion by prevailing winds, but the direction of which isaltered by the rotation of the earth (Coriolis Force). The bestknown of these currents is probably the Gulf Stream in theNorth Atlantic; the Kuroshio Current in the North Pacific is asimilar current, and both serve to warm the climates of theeastern edges of the two oceans.

The ocean serves as the largest home/shelter ofseveral marine species.Because of it’s unique composition and structure, themarine animals learned to adopt from the extremeenvironment.Provides marine plants that play a crucial role tomankind.The marine plants such as phytoplankton and algaeprovides much of the world’s oxygen supply and takein huge amount of carbon dioxide. Thus, theabsorption of this gas is a useful tool in reducing theseverity of climate change.I t s I m p a c t t oB i o d i v e r s i t y
The ocean not just serves as the home of thewonderful creatures but it also enhances thecharacteristics of these animals.Provides life not only for the marine animals but alsoto mankind.---------------------------------------------end-------------------------------------------
