Document Summary
Rain, water, and other types of presicipitation sculture the planet: ex: mountains, valleys, rivers, lakes sculpture the planet. Affects the climate: near seashore has milder climate: milder climate areas closer to large areas of water. High concentrations of pollutants can affect our biological processes. Withdrawal- total amount of water removed from a river, lake or aquifer for any purpose. Quantity of water how much fresh water is available? (look at diagram on lecture slide) When someone wants to withdraw, should look at how much water is actually available. All water on earth: 97. 4% is ocean and saline lakes. Fresh water: 1. 984$ is icecaps and glaciers. 0. 592% is groundwater. Some areas have lots of water but the largest rivers are far from agricultural and population centers. Lots of precipitation arrives during short period but cannot be collected and stored. In dry areas, water should be collected, stored and used when in need later on.
