Buffer: a wide strip of vegetation along a body of water, retained for the purpose of protecting water quality and aquatic habitat.
Condensation: the process of water vapor in the atmosphere turning into liquid water forming clouds.
Erosion: the natural process by which Earth’s surface is worn away by the forces of wind and water—water running downhill is the primary agent in shaping topography.
Evaporation: the process of liquid water turning into water vapor from water and land surfaces.
Groundwater: water that is stored beneath the surface of the land, in spaces between rocks and soil particles—this water oft en supplies wells or springs.
Infiltration: the process by which water from the ground surface enters the soil.
Precipitation: occurs when so much water has condensed that the air can’t hold it anymore and it falls back to Earth as rain, snow, sleet, hail, frost, dew, etc.
Riparian Area: the area next to a river or stream inhabited by plants and animals that requires constant moisture.
Runoff: water that does not infiltrate the soil, but runs off the surface of the land.
Spring: the point where groundwater flows out of the ground.
Topographic Map: a map showing changes in elevation, land features, etc.
Transpiration: the process of water that has been taken up by plants, evaporating from the leaves of plants.
Watershed: an area of land where water and sediments drain into a common stream, lake or bay.
