C. A System
 Part of the Universe that can be studied separately
– Closed System- a system in which energy can enter or leave, but matter cannot
– Open System- a system in which there is a free exchange of both energy & matter between the system & its surroundings.

a) Evaporation  The process by which water is added to the atmosphere as liquid water is heated and turned to water vapor
 Transpiration – the evaporation of water from plants
 Evapotranspiration – the changing of liquid water to water vapor from the ground, plants & animals
b) Condensation
 Water vapor rises into the air, expands & cools
 Liquid water eventually forms clouds
-Cooling water vapor turns to liquid water
c. Precipitation
 Any form of water falling from the sky -Rain, Snow, Hail, Sleet
 Soaks into the ground to recharge the water table -Runs off the land into a river or other body of water
 Or evaporates to start the process over
d. Water Budget

2. Carbon Cycle
 _____________________________________________________________________________________
_____________________________________________________________________________________
 Carbon is the ___________________________________________
– Carbon is changed into different _________________________ as it goes through the cycle
CH4 = ________________________
CO2 = ________________________
C6H12O6 = ________________________________________________
 Carbon enters atmosphere as Carbon Dioxide (_______):
– ______________________________________________________________
6
O2+Food = CO2+H2O+Energy
– Produced by ______________________________
-Released by ______________________________
– Released by ______________________________
– ____________________________________________________________________________________
 Carbon leaves atmosphere as CO2
__________________________________________________________________________________________________________________
________________________________________________________________________________
– ________________________________________________________________
 Carbon is stored in _____________________________________________________________________
 __________________________________________________________________
 Or __________________________________________________________________ settles to bottom & becomes ______________________
 Ocean is known as a _______________________________ because it _____________ carbon
 Carbon dioxide from Atmosphere is dissolved in the ocean _____________________________________
– Forms ____________________________________________________________________________
3. The Energy Cycle
 ____________________________________________________________________________________________________________
 The amount of energy that __________________the system should = the amount of energy that is ____________________
