Human Impact on the Hydrosphere

Groundwater and How we Use it NonPoint Water Pollution Explained Click to watch the video. Point versus Non-point Source Pollution For each example, sort into the appropriate category. Point source pollution pipe from a paper mill factory drains into a river coal ash pond leaks into the Dan river sewage tank leaks into well water wastewater treatment plant has pipe that drains into a lake a chemical is added to a stream to eliminate all of the mosquito larvae China discharges their waste to a remote area in the ocean Non-point source pollution acid rain oil heavy metals deposited on roadways from cars trash is left behind by a river after a party a hog farm does not dispose of it's animal waster, and it becomes run off fertilizers from a farm that are rich in nitrates washes downhill after a big rain salt added to roads after a heavy snow is washed onto the land surrounding the road Match the term with the description Clean Water Act Legislation to ensure clean water EPA Government agency in charge of enforcing laws to ensure clean water Permeable water can pass through Impermeable water cannot pass through Saturated no more water can be held Unsaturated There is more room for water Causes of water pollution Acid Rain changes the makeup of water as the precipitation falls Non-point pollution toxic chemicals and compounds make their way into the water system just the same—through rainwater drainage, melting snow, and running rivers Point pollution emissions which enter water bodies from an easy-to-identify single source, such as a pipe from a factory or the outfall from a sewage works Fertilizer primary sources of nutrient pollution from agricultural sources. Excess nutrients can impact water quality What is Eutrophication? Welcome to CK-12 Foundation Read through the article for more information about pollution. Pollution Article: Click to Read the ArticleUse your textbook for a resource as needed. Which industry consumes the most water? Power Plants The Public Agriculture Aquariums How does acid rain form? From eutrophication From pollution of cars, factorues, etc. From pollution of nitrogen None of the above Groundwater can become polluted from contaminants (pollution) of surface water True False Condensation happens before evaporation in the water cycle True False Where is most of the Earth's freshwater located? Canada The ocean Streams Glaciers Eutrophication decreases the amount of oxygen in water True False Which set of surface soil conditions on a hillside would result in the most infiltration of rainfall? gentle slope, saturated soil, no vegetation gentle slope, unsaturated soil, vegetation steep slope, saturated soil, vegetation steep slope, unsaturated soil, no vegetation During a heavy rainstorm, runoff is most likely to occur if the surface soil is firmly packed clay-sized particles loosely packed sand-sized particles covered by trees, shrubs, and grasses unsaturated and has a gentle slope Which soil condition usually exists when flooding occurs during a rainstorm? The soil is unsaturated. Soil water storage is equal to zero. Soil infiltration is increasing Soil permeability is equal to the rate of precipitation. Apartment buildings and parking lots completely cover an area that was once an open, grass covered field. What factor most likely increased because of this construction? infiltration into the ground runoff the level of the water table permeability Pesticides and herbicides are examples of nonpoint source pollution True False The Water Cycle Fill in the processes of the water cycle on the image below using the following words (BE SURE TO SPELL THEM CORRECTLY!): transpiration, infiltration, runoff, evaporation, precipitation, condensation, groundwater flow Evaporation Transpiration Condensation Precipitation Infiltration Groundwater flow Runoff Label the image below of groundwater using the following words: Zone of saturation, Water table, Zone of aeration.Capitalize your answers like the above choices.
