  2. Pacific world's largest ocean at 60,060,700 mi2 (155,557,000 km2) it covers 28% of the Earth = nearly all of the land area on the Earth deepest point is the Challenger Deep within Mariana Trench 35,840 feet (-10,924 m) important to geography not only because of its size but it has been a major historical route of exploration and migration

  6. Water changes everything freshwater is not evenly distributed throughout the world ½ of the world's water supply is contained in just 9 countries: [source: World Business Council for Sustainable Development] United States Canada Colombia Brazil Democratic Republic of Congo Russia India China Indonesia

  7. Water changes everything urban areas, have a greater need for water beyond the basics for drinking and sanitation overpopulation in undeveloped countries means that many people don't even get the basics most of the world's freshwater ~ 2.4 million mi3 (10 million km3) is contained in underground aquifers the rest comes from: rainfall (after accounting for evaporation): 28,500 mi3(119,000 km3) man-made reservoirs: 1,200 mi3 (5,000 km3) lakes: 21,830 mi3 (91,000 km3) rivers: 509 mi3 (2,120 km3) [source: World Business Council for Sustainable Development]

  8. some countries don't have enough clean water for their rapidly growing populations, and they can't afford the infrastructure necessary to clean and transport it most people in China's cities suffer from water shortages, and most of China's groundwater, lakes and rivers are polluted ~ 700 million Chinese people have access only to drinking water that does not meet standards set by the World Health Organization countries in the Middle East use the least amount of water per person because there are so few natural sources of freshwater in contrast, the usage of water is higher in the United States than in any other country, ~ 60,000 ft3(1,700 m3) of water used per person in 2002 [source: Organization for Economic Co-operation and Development] even within the United States, there are some states and regions that don't contain enough water to supply their populations coastal regions of Florida have so much saltwater that they must have freshwater piped in from inland areas, which has led to political disputes over control of the water supply
