area - ANSWERthe amount of space on the surface (2D)
formula: length x width OR pi x radius^2
Google Earth - ANSWERa geographic information system (GIS) that shows a 3-D representation of the
Earth's surface that shows spatial data and contains attribute data for numerous points
surface runoff - ANSWERwater that flows over the land as a result of rainfall or snowmelt
volume - ANSWERthe amount of space occupied by an object (3D)
formula: length x width x height OR area x height
impervious surface - ANSWERan area of the ground surface that water cannot penetrate, producing
more surface runoff (i.e. parking lots)
imperviousness - ANSWERthe scalar value applied to an impervious surface to describe how much
water can penetrate into the ground and how much becomes surface runoff (also, on a scale from 1-
10)
stream system - ANSWERthe watershed or drainage basin
tributary - ANSWERa smaller stream that flows into a larger one
concentration - ANSWERthe strength of a solution
formula: mass(mg)/volume(L)
pollutants - ANSWERunwanted chemicals or other materials found in the water that may damage the
environment into which they are introduced; the concentration is important to consider
(i.e. pesticides, fertilizers, oil, gas, sewage, anti freeze, pet waste, chemical waste, household
