  6. Hydrosphere "This comprises all water resources both surface Surfoce Water All Weter Water on Earth and ground water. The world's water is found in oceans and seas, lakes and reservoirs, rivers and streams, the Polar Regions in addition to ground water below the land areas. The distribution of water among these resources is as under Freshacter 1% Oceans and Seas 96-97 % 9 -Glaciers and polar icecaps 2-3 % -Fresh water <1% "The water locked up in the Oceans and Seas are too salty and cannot be used directly for human consumption, domestic, agriculture or Industrial purposes only less than 1% of water resources are available for human exploitation. Water is considered to be a common compound with uncommon properties. These uncommon properties (e.g. anomalous expansion of water) are mainly responsible for supporting terrestrial and aquatic life on earth 2% . OCEAN 10
