| Runoff | water that flows over land into rivers, lakes, and oceans |
| Precipitation | water that falls from the atmposhpere (rain, sleet, snow, hail) |
| Sun | the energy source that drives the water cycle |
| Water Cycle | the movement of water between Earth's Surface and the atmosphere |
| Evaporation | When the sun's energy changes liquid water to water vapor |
| Condensation | Water vapor cools and changes back to liquid water |
| Conduction | heat transfer through touch |
| Radiation | heat trransfer through waves |
| Convection | the transfer of heat through liquids and gases |
| Conductor | a material through which heat moves easily (like metal) |
| Chemical Change | a change in which new matter is formed (like burning wood) |
| Physical Change | a change in which no new materials form (like water melting) |
| Transpiration | when plants release water vapor into the atmosphere |
| Insulator | A material through which heat does NOT move easily (like rubber) |
