(32 cards)
water and neutrients must be ___ to sustain life
recycled
hydrologic cycle
water cycle
tge human body losses and recycles how much of its total H2O volume daily
3%
Plants lose H2O tgrough
transpiration
Plants take in H2O how
from roots through stomata
cellular respiration produces ____
metabolic H2O
H2O capour is a ____ that ___
greenhouse gas that traps and transfers heat
H2O is cycle through the
hydrologic cycle
evaporation
changing water from liquid stare to gaseous state
transpiration
ecaporation of water from plant leaves
precipitation
rain snow hail etc
percalation
movement of water through soil and pearmable rock
condension
collection of water droplets in the atmosphere to form clouds
resevoirs
where something is naturally found
resevoirs of water
oceans rivers streams ground water snow ice
waters unique properties 4
universal solvent
high melting and boilling point
high heat capacity
special cohesive and adhisice properties
Water is a universal solvent meaning
water molecules are polar (diffrent charges at each end) resulting inva weak attraction between molecules known as a hydrogen bond which allows water to dissolve verity of substances
water gas high melting and boiling point which means
a lot of energy is required ti break hydrogen bonds to change state
water melting point
0
water boiling point
100
density in water
as it gets colder the water molecules loosen which is opposite of normal substances
when it gets hotter molecules tighten causing higher density
water has high heat capacity meaning
large amounts of energy required ti increase temperature and large amounts of energy are given off when when water water temperature drops
energy from water > heats the
land
energy from pand> given to
given ti water to cool the land
