Science Hydrologic Cycle
| Term | Definition |
|---|---|
| Accumulation | The process in which water pools in large bodies (like oceans, seas, and lakes |
| Condensation | The process in which water vapor in the air turns into liquid water. Condensing water forms clouds in the sky. Water drops that form on the outside of a glass of icy water are condensed water. |
| Evaporation | The process in which liquid water becomes a water vapor. Water vaporizes from the surfaces of oceans and lakes, from the surface of the land, and from melts in snow fields. |
| Precipitation | The process in which water (in the form of rain, snow, sleet, or hail) falls from clouds in the sky. |
| Subsurface Runoff | Rain, snow melt, or other water that flows in underground streams, drains, or sewers |
| Surface Runoff | Rain, snow melt, or other water that flows in surface streams, rivers, or canals. |
| Evapotranspiration/Transpiration | The process in which some water within plants evaporates into the atmosphere. Water is first absorbed by the plant's roots, then later exits by evaporating through pores in the plant. |
| Percolation | The subsurface movement of water through the soil to the water table and the groundwater. |
