
All of the ___________ on planet
Earth
“___% of the earth is covered by
water and only 29% is terra firma”
(University of Florida).
“______ Planet” – water is not found
on any other planets in our solar
system.
“It is because the Earth has just the
right mass, the right chemical
composition, the right atmosphere,
and is the right distance from the Sun
(the “_________" principle) that
permits water to exist mainly as a
liquid” (U of F).





The great variety of surface temperatures and pressures allows
water to exist in all three states.
 Solid = _____________
 Liquid = _____________
 Gas = _________________
The ________________ contain most of the water (approx. 1.35
million cubic metres)
The ___________ heat capacity of water and the ___________
volumes of water “_________ the Earth surface from large
temperature changes such as those observed on the moon” (U of F
Hydrosphere).
“Water is the universal _____________ and the basis of all
_______ on our Planet” (U of F Hydrosphere).
“Benjamin Franklin to comment[ed] "When the well's dry, we know
the worth of water.“” (U of F Hydrosphere).

 _______________, _______________, nitrous oxide, and
____________________________
 “these "greenhouse" gases _____________ heat energy
emitted from the earth surface and ____________ global
temperatures (global warming)” (U of F Atmosphere).
 “In addition, chloroflurocarbons are effective at depleting the
Earth's ______________ shield that protects the earth
surface from the harmful effects of ultraviolet radiation” (U of
F Atmosphere).
