Chapter 10: The Hydrologic Cycle
Water: A vital resource
water quality: water pollution and its consequences on sewage-treatment facilities and on public policies for dealing with pollution issues
water quantity: on the global water cycle and how it works, on the tech we use to control water and manage its use, and on public policies we have put in place
97.5% of the planet's water is salt, 2.5% of water is fresh water
Hydrologic Cycle and human impact
capillary water: the water may be held in the soil in an amount that depends on the water holding capacity of the soil
condensation: the water from evaporation and transpiration being formed into clouds
precipitation: liquid form the clouds (rain)
adiabatic warming: occurs as cold air descends and is compressed by the higher air pressure in the atmosphere
global convection currents are the differences on Earth's surface to be better in some places than others and drive great air movements
adiabatic cooling: as the warm air encounters the lower atmosphere pressure at increasing altitudes, it gradually expands and cools
transportation: water from plants being turned into gas
runoff: water from precipitation not being able to soak up into the ground
evaporation: water from the soil changing into a gas state
infiltration: water from precipitation being absorbed into the soil
Humans impact on the hydrologic cycle from GCC is making it occur faster
Hadley cycles: warm, moist tropical air being dropped off as cool, moist air making a desert region
Water: getting enough, controlling excess
a lot of the water form the west US is ground water from an aquifer
confined aquifer
unconfined aquifer
worldwide use of water
2) industry (20%)
3) human use (10%)
1) irrigation (70%)
Water stewardship, economics, and policy
Blue Revolution: a radical change in the way we use water
desalt saltwater, desalination of water for domestic use
conserve present supplies by using less water, instead of using irrigation, carefully watering plants
gain better access to existing groundwater
making food production more efficient
capture more of the runoff water, use rain barrels
