| hydrologic cycle | | Evaporation of water from the leaves of a plant |
| condensation | | The removal of trees faster than forests can replace themselves. |
| transpiration | | Precipitation falls on the windward side of a mountain range, resulting in lush vegetation and a warm, moist climate on one side of the mountain, but a desert area on the far side. |
| infiltration | | the process by which water on the ground surface enters the soil |
| deforestation | | water that flows over the ground surface rather than soaking into the ground |
| evaporation | | Any form of water that falls from clouds and reaches Earth's surface; examples include rain, snow, sleet, and hail |
| precipitation | | minute-by-minute changes in the atmosphere |
| runoff | | what the weather is like over a long period of time in a specific area |
| rain shadow effect | | elevation; height above sea level |
| climate | | distance north or south of the Equator, measured in degrees |
| weather | | the change of state in a substance from a liquid to a gas |
| latitude | | A warm ocean current that flows from the Gulf of Mexico northward through the Atlantic Ocean |
| altitude | | the process in which water vapor in the atmosphere is changed into a liquid state. In the atmosphere, this may appear as clouds or dew. |
| Gulf Stream | | the continuous circulation of water in the Earth-Atmosphere system; also known as the water cycle |
