Water Cycle

Quiz on 11/13/13

Absorption Precipitation soaking into the ground
Aquifer Ground water stored in and between rocks; underground water storage
Condensation When water vapor turns into liquid water and becomes visible as a cloud, fog, or water droplets
Evaporation When liquid water turns into water vapor
Groundwater Water that is under the surface of the ground
Humidity Amount of water vapor in the air
Precipitation Water in the form of rain, snow, sleet, or hail
Run off Water that is not absorbed so flows downhill, usually into a body of water
Surface Water Water that is not absorbed and collects in ponds, lakes, streams, or rivers
Transpiration Water that 'sweats' and evaporates from a plant, mostly from the underside of the leaves
Water Shortages occur when people use water in an area faster than the water cycle can replace it
Pollutants *Some can make water unpleasant to drink or wash in *Some can cause sickness or even death
Sewage The water and human wastes that are washed down sinks, toilets, showers, and laundry tubs
Sediments Particles of sand/rock/soil picked up by erosion
Household Sewage If sewage isn't treated to kill disease-causing organisms, the organisms quickly multiply People become ill if they drink or swim in water containing these organisms
Oil and Gasoline *Oil spills can take many years for an area to recover from an oil spill *Oil and gasoline can leak out of damaged underground storage tanks *and be carried away by a leaking tank by groundwater
Heat Heated water from factories can have a negative effect by killing organisms living in the body of water into which it is released
Agricultural Wastes Rain can wash animal wastes and fertilizers into ponds, were they cause algae to grow blocking the sunlight from plants and killing them
Industry and Mining Chemicals and metal wastes can harm organisms that live in bodies of water or eat the organisms that live in them can also become ill
Sediments *Can cover up the food sources, nests, and eggs of organisms in bodies of water *They also block sunlight preventing algae and plants from growing
Federal, state and local laws regulate The use and cleanup of water pollutions
Sewage Treatment Plants *Waste water is filtered to remove solid materials *In tanks, heavy particles settle out *Bacteria breaks down wastes *Chlorine kills disease-causing organisms
Reducing Pollutants *Industries can recycle their wastes to recover useful materials *Companies can change their processes to produce less waste or less harmful waste *Farmers are finding alternatives to toxic pesticides and fertilizers
Never pour common household *Chemicals down the drain *Save them for the next "Hazardous Waste Collection Day"
Cleaning Oil Spills *Oil is a pollutant that nature can handle in small amounts * Bacteria in the ocean can break down oil *But for large spills, bacteria can't clean up the spill fast enough *Gasoline or oil that leaks from an underground tank is hard to clean up
Cleaning Oil Spills (Part2) Cleaning up spills can take many years
Multiple solid waste
Three methods of handling m.s.w.
Advantages of Incineration
Disadvantages of Incineration
Sanitary Landfill
Advantage of Sanitary Landfill
Disadvantages of Sanitary Landfill
Advantages for recycling
Products that are not Biodegradable
Recyclable metals
Some recyclable plastics can be made into
Recyclable glass can be made into
Paper can be recycled only a few times because
