rate of precipitation
water table level
amount of pollution in a nearby stream
As human population increases exponentially, what happens to the amount of freshwater?
it increases
it decreases
it stabilizes
it increases then decreases
High levels of which is likely to improve biotic index of a stream?
algae growth
decaying matter
suspended solids
dissolved oxygen
Which is the most common contamination source for freshwater resources?
runoff
digging wells
melting of glaicers
lightening
Which is true of man-made dams?
reduce risk of upstream flooding
don't affect the character of the dammed river downstream
located where they don't affect preexisting farms
provide more dependable water resources for humans
How can you maximize freshwater resources?
increased infiltration to fertilize crops
reduced treatment by waste water treatment plant
reduce measures to prevent arsenic contamination
law regulating the amount of pollution dissolved in a river
Which is a non-point source of pollution?
toxic waste given off by a chemical research facility
exhaust from car tailpipes
emissions ejected from smokestacks
fertilizers washed away from farmlands by runoff
Why are ocean current important to coastal regions?
they produce high and low tides
they can warm or cool the air temps
they can vertically push warm water and nutrients up
they increase the rate of precip. as cold water moves in
What is true about seawalls?
they protect coastal areas but cause erosion
they don't protect coastal areas but reduce erosion
they protect coastal areas and reduce erosion
they don't protect coastal areas and cause erosion
What is formed when impermeable rock forces ground water to move up to the Earth's surface?
spring
aquifer
geyser
well
What is a drawback to the extensive use of irrigation?
crops don't receive sufficient water
flooding increases
groundwater levels decrease
pollution increases
Which can cause the salinity of a town well to increase?
increases in global temperature
decreases in use of irrigation
glacial melting
saltwater intrusion
Which is true of groundwater and surface water?
more groundwater then surface water increases
more groundwater then surface water decreases
less ground water then surface water increases
no connection between the two
How is the beach structure beneficial in protecting recreational beaches?
it accelerates sediment loss
it creases sand dunes along the shoreline
it reduces sediment loss and controls erosion
they reflect waves and reduce flooding
This shows expansion around a lake for 30 years. What happens to the ground and surface water?
they both improve
they both get worse
groundwater gets better and surface water gets worse
groundwater gets worse and surface water gets better
