Document Summary
71% of the earth is covered by water. Water is heavy: every 10 m in depth corresponds to 1 kg/cm2 in pressure, at the known deepest spot on the ocean bottom (mariana trench), pressure would be 1. 1 ton/cm2. James cameron: the first human to reach the 6. 8-mile-deep undersea valley solo. Most of the land is located in the northern hemispheres.

Everest 8848 m (29,028 ft: average temperature: 3. 9"c (39"f, average salinity (amount of salt): 3. 4, age: about 4 billion years. Utilization of the ocean: transportation, natural resources (food, mineral, oil, gas, energy, high concentration of human population in the coastal region, pollution, naval power. The climate system: atmosphere, ocean, sea-ice, biomass, river and lakes, human activities. What drives the climate system: solar radiation.
