The Water Cycle
Anything written in yellow (SLOW down and pay attention) is useful information. You should write it in your notes IN YOUR OWN WORDS.
Anything in red (STOP and pay close attention) is critical information and should be copied exactly.
Anything in green (GO on to the next point) you do not have to write.

6 processes:
EvaporationCondensationInfiltrationPrecipitationRunoffTranspiration
How many processes are there in the water cycle?
Evaporation: The process of where a liquid (H2O) changes from a liquid state to a gaseous state.
Role:Required for clouds to form and precipitation to
occur.Oceans account for 80% of the water delivered as
precipitation.
What role does evaporation play in the water cycle?
Process of a gas cooling to a liquid state.Role:
Allows water vapor to form into a cloud.Clouds travel across land and deposit rain.
What is condensation?
is any product of the condensation of atmospheric water vapor that falls under gravity.
Role:Replenishes water levelsWaters cropsCools Temperatures/lowers pollen levels
What is precipitation?
Brain
Snack
Name the forms of
precipitation
Water is absorbed into the ground through the soil and underlying rocks.
Role:Water needs to be
absorbed in order to replenish the ground water and aquifers.
Excess rainfall can cause runoff and flooding.
What purpose does infiltration serve in the water cycle?
Runoff is the movement of landwater to the oceans, chiefly in the form of rivers, lakes, and streams
What is runoff?
process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
Similar to sweatingAbout 10% of the moisture in the
atmosphere comes from transpiration. (from USGS)
What is transpiration?
Evaporation
Condensation
Infiltration
Precipitation
Runoff
Transpiration
