Oceanography is the science that studies the oceans along with marine organisms and ecosystem dynamics, ocean currents and waves, plate tectonics and the geology of the sea floor, and the chemical substances and physical properties of the world oceans. study the composition of seawater, its processes and cycles, and the chemical interaction of seawater with the atmosphere and sea floor. analyze seawater components, the effects of pollutants, and the impacts of chemical processes on marine organisms. use chemistry to understand how ocean currents move seawater around the globe and how the ocean affects climate or to identify potentially beneficial ocean resources such as natural products that can be used as medicines. The surface of the planet is approximately 71% water and contains (5) five oceans: Arctic, Atlantic, Indian, Pacific and Southern. By Size Greatest Depths Pacific - 155,557,000 sq km Atlantic - 76,762,000 sq km Indian - 68,556,000 sq km Southern - 20,327,000 sq km Arctic - 14,056,000 sq km Mariana Trench, Pacific 35,827 ft Puerto Rico Trench, Atlantic 30,246 ft Java Trench, Indian 24,460 ft Arctic Basin, Arctic 18,456 ft Southern Ocean, 23,737 ft Surface Area of the Planet (510,066,000 sq km) Land Area on the Planet (148,647,000 sq km) 29.1% Ocean Area (335,258,000 sq km) Total Water Area (361,419,000 sq km) 70.9% Type of Water (97% salt), (3% fresh) The Ring of Fire coincides with the edges of one of the Pacific Plate which is world's main tectonic plates. It contains over 450 volcanoes and is home to approximately 75% of the world's active volcanoes. Nearly 90% of the world's earthquakes occur along the Ring of Fire; most recently, the devastating quakes in Chile, Japan and New Zealand. Water covers 71% of the surface of the earth. This fact is combined with the great depth of many of the oceans (average depth 3700 m / 12140 ft.) provides
