water cycle
 Water repeatedly moving from Earth to the air and
then back again
evaporation
 Water is warmed by the sun and moved in to the air as
water vapor
condensation
 Cooled water vapor from the air turns back in to
liquid
precipitation
 Water that falls to the surface of Earth in the form of
rain, snow, sleet, and hail
Humidity
 Amount of water vapor in the air
Runoff/Surface Water
 Water that is not absorbed back into the ground
Ground Water
 Water that is absorbed into the ground and stored
under the Earth’s surface
transpiration
 Water is absorbed by plant roots and then unneeded
water evaporates from the leaves’ stomata (pores on
the leaf)
biotic
 Living components of the environment
 Water (abiotic) is needed by aquatic fish, plants,
animals…
abiotic
 Non living elements such as water, dirt, rocks…
