Diagram of the water cycle
Facts about the water cycle
• The chemical symbol for water is H2O
• The sun is the driving force of the water cycle
• Only 3% of water on earth is freshwater
• When ever water changes from one state to another and moves from one place to another, it either gives off or absorbs energy
Runoff/Collection
EvaporationCondensation
Precipitation
Note: If precipitation is absorbed by a plant, then it goes through transpiration (releasing water from its leaves) rather than evaporation
Words to know
Water cycle - the continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation
Evaporation - the process by which molecules at the surface of a liquid absorb enough energy to change to a gas
Condensation - the change in state from a gas to a liquid
Precipitation - any form of water that falls from clouds and reaches earth's surface as rain, snow, sleet, or hail
Transpiration - the process through which water is lost through a plant's leaves
Runoff - water that flows over the ground surface rather than soaking into the ground
Ready for some questions?
Question #1
o Which step of the water cycle turns water vapor into clouds?
Correct!
Water Vapor Condensation Clouds
Question #2
o What happens after a plant absorbs water?
Correct!
o Transpiration - the process through which water is lost through a plant's leaves
Question #3
o How much of earth’s water is freshwater?
Correct!
o Only 3% of earth’s water is freshwater
Saltwater Freshwater
Question #4
o What is the chemical symbol for water?
Correct!
H2O
Question #5
o Where does the energy that powers the water cycle come from?
Correct!
o Energy from the sun powers the water cycle!
Now time for some bonus questions…
Bonus #1
o What does H2O mean?
