include coal, petroleum, and natural gas

TERM 17

global warming

DEFINITION 17

the progressive increase of the earth's average temperature

due to increased concentrations of greenhouse gases

TERM 18

greenhouse

gases

DEFINITION 18

water vapor, methane (CH4) , carbon dioxide (CO2)

TERM 19

greenhouse effect

DEFINITION 19

the trapping of the sun's warmth in the lower atmosphere of

the earth by greenhouse gases

TERM 20

"natural" greenhouse effect

DEFINITION 20

keep the earth's climate warm and habitable

"man-made" greenhouse effect

enhance the natural effect by adding greenhouse gases from

fuel burning

TERM 22

how to maintain a balance between carbon

and energy

DEFINITION 22

respiration and burning of fuel- produces CO2 and releases

energyphotosynthesis- absorbs CO2 and fixes solar energy
