major processes in the WATER CYCLE that affect groundwater and surface water are
runoff, infiltration, precipitation, transpiration, evaporation, condensation
Water can return to the atmosphere through the process of evaporation or ______ from plants
An area drained by a river and its tributaries is called a/an
watershed or river basin
the line of mountains which separates eastern flowing water from western flowing water
What is a River basin
a watershed-land area that drains into a river or a common body of water
What is the river basin for Charlotte, NC?
rock holding water underground
Zone of Aeration
area above the water table that contains air spaces in soil
Zone of Saturation
area below the water table that contains groundwater, saturated
line that separates the zone of aeration and the zone of saturation
portion of aquifer that contains rock material that does not allow water to penetrate; clay and granite,
portion of aquifer that contains porous rock material that allow water to penetrate freely; sand and gravel
lies between 2 layers of less permeable rocks and is filled with water.
covered by permeable rock and can receive water from the surface. The water table of an unconfined aquifer rises or falls depending on the amount of water entering and leaving the aquifer. It is only partly filled with water.
volume of space between or cracks or rocks
measure of time in which a fluid (water) can move through a porous rock
How does a sinkhole form?
underground air pocket suddenly collapsing; layer of limestone
groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land's surface can move through the soil and end up in the groundwater.
highly efficient, self-contained, underground waste-water treatment system. household waste
single, known, specific source;
factory producing chemicals (air)
company tank is drained into stream (water)
oil from garage is dumped into ground (soil)
Non-point source pollution
very broad, not a specific point of origin;
people driving cars (air)
Acid Rain (water)
Harmful pollutants enter soil from air/water
three main functions of wetlands
home for wildlife,
filter-they clean water
soak up the water and help prevent flooding
used water from homes and businesses; toilets
precipitation that drains into a street drainage system where it flows into streams/creeks.
confined aquifer containing groundwater which is under presser causing water in the well to rise
a river or stream flowing into a large river or lake
cloudiness of water;
The more suspended solids in the water, the darker and higher turbidity,
the sediment absorbs heat making water warmer so decreases oxygen in water;
place the following phrases in the flowchart in correct order: ALGAE BLOOM, FISH DIE, DECOMPOSING ALGAE, LOW OXYGEN LEVELS, EXCESSIVE FERTILIZER RUNOFF
A healthy Stream
living plants/animals (macroinvertabrites), rocks
Naturally vegetated area along a river;
helps keep areas from flooding, filters out pollutants such as parking lot oil, sediment and fertilizer, slows water down
triangular deposition of sediments deposited by a river at its mouth.
