| evaporation | the process of changing from a liquid to gas (water vapor) |
| precipitation | the process of condensed water vapor valling from the sky as rain, sleet, snow, hail |
| transpiration | the process of water vapor moving through small openings in the leaves of plants |
| condensation | the process of a gas becoming a liquid |
| runoff | water that runs off the land into a river, stream, or lake |
| watershed | a drainage basin; a land ara whose water drains into a stream system |
| dissolved load | materials that are dissolved in a stream's water and carried away in a solution |
| suspended load | particles small enough to be held up by the turbulence of a stream's moving water are carried away in suspension like silt, clay and sand |
| bed load | sand, pebbles, and cobbles that the water in the stream roll or push along the bed |
| floodplain | broad, flat area that extends out from a stream's bank and is covered by excess water during times of flooding |
| meander | erosion causing a bend or curve |
| lake | a depression in the earth's surface that holds water |
| wetland | a land area that is covered with water a large part of the year |
| stream bank | ground bordering each side of a stream that keeps the moving water confined |
| stream channel | narrow pathway carved into sediment or rock by the movement of surface water |
| solution | silica, calcium, and sodium are dissolved in a stream's water |
| delta | triangular shaped deposit consisting of clay and silt that forms where a stream enters a large body of water |
| rejuvenation | process during which a stream resumes downcutting toward its base level, increasing its rate of flow |
| eutrophication | process by which lakes become rich in nutrients from the surrounding watershed, resulting in a change in the kinds of organisms in the lake |
