|
water cycle
|
evaporation, transpiration, condensation, precipitation, gravitational flow
|
|
|
humidity
|
amount of water vapor in the air
|
|
|
adiabatic cooling
|
warm rises from earth's surface because it is less dense. as it encounters lower atmospheric pressure at increasing altitudes warm air cools as it expands
|
|
|
adiabatic warming
|
cool air descends and is compressed by higher air pressure in lower atmosphere
|
|
|
convection currents
|
equator
|
|
|
hadley cell
|
system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating weather patterns
|
|
|
infiltration
|
precipitation soak into ground
|
|
|
capillary water
|
water held in soil in amound depending on water holding capacity of soil
|
|
|
evapotranspiration
|
evaporation and transpiration
|
|
|
percolation
|
infiltrating water that is not held in soil is called gravitational water because it trickles down through pores under pull of gravity
|
|
|
changes to earth's surface
|
land is changing pathway of water cycle is shifted from infiltration and groundwater recharge to runoff, so water runs into streams. can cause flood and get pollutants
|
|
|
climate change
|
earth's climate is warming, water cycle is being altered, warmer means more evaporation because evaporation increases with temperature. heavier precipitation and more floods, droughts
|
|
|
atmospheric pollution
|
more aerosol particles impact hydrologic cycle=suppress rainfall and atmospheric cleansing does not occur
|
|
|
withdrawing water supplies
|
we make use of surface and groundwater
|
