Watercycles
the movement of water is not restricted to earths surface water sinks deep into the ground and rises high into the atmosphere. it is this movement of water which is known as the WATER CYCLE.
vocab
freshwater freshwater is water, whether liquid, solid, or gas that contains a low concentration of dissolved salts
salinity the average concentration of salt
estuaries where rivers flow into an ocean,are affected by tidal action.
water cycle the movement of water
precipitation rain, sleet, snow, hail
groundwater water that has soaked into the soil.
percolation gravity causes water to sink into the ground, dissolving salts and minerals as it moves through the spaces between the soil
saturated zone the water eventually reaches a layer of clay, slit, or rock that will not allow it to pass through fast enough to be used as a water supply. as more rain falls, the water completely fills the spaces above this this is called the saturated zone
water table the upper level of the saturated zone is called the water table
capillary action draws more water up from below ground
aquifers large accumulation of underground water in permeable rock, soil, or sand
sediment gravel, sand, silt, and mud
weathering the breakdown of rock into sediments.
erosion the wearing away of earths surface caused by the movement of materials from one place to another. deposition when sediment starts to settle to the bottom of a lake or river.
delta a flat area of land formed by sediment that has settled at the mouth of a river over millions of years.
flood plain a relatively flat area on either side side of a river that floods when the water levels get higher.
dikes long walls of soil built along the banks of a river to prevent flooding.
acid precipitation when water vapor reacts with airborne pollutants, particularly sulfur dioxide and nitric oxide.
sanitary sewage water from sinks, baths, washing machines,and toilets.
storm water rain water and melted snow that runs off streets and the surfaces of land.
sludge the solids in sewage are settling tanks. here, larger particles settle to the bottom to create sludge.
effluent the treated water that is released back into the environment.
