| A | B |
| transpiration | water from leaves |
| evaporation | liquid to gas due to heat |
| condensation | gas to liquid due to cooling |
| precipitation | falling water |
| run off | precipitation that is not absorbed by the ground |
| leeching | water that is absorbed into the ground |
| water table | water under the ground |
| decomposition | water is released as organisms break down |
| types of precipitaiton | rain, snow, hail, sleet |
| fog | water vapor condensing at ground level |
| cloud | water vapor condensing in the sky |
| photosynthesis | makes sugar whichis carbon, when plants die, carbon goes into the air |
| respiration | carbon dioxide is a waster product of respiration |
| fossil fuels | dead organisms that have been under pressure for millions of years, oil, coal are examples |
| greenhouse effect | good, when the sun's rays get trapped in the Earth's atmospher due to carbon dioxide |
| global warming | too much carbon dioxide traps too much heat |
| carbon sink | most carbon ends up at the bottom of the ocean |
