Today's Objective: How are infiltration and runoff related? Do Now: Explain the difference between infiltration and runoff Infiltration the seeping of water into the soil to become groundwater Runoff the moving of liquid water on the surface of Earth  Infiltration and runoff are opposites, water that does not infiltrate the soil will runoff into a larger body of water  Factors that Affect Groundwater: Gradient (Slope) Gentle Gradient More infiltration As gradient Steep Gradient decreases More runoff infiltration increases. Soil Composition (size) As particle size increase the rate of infiltration increases. Large Small Particles Particles More More runoff infiltration Soil Composition As particles go from unsorted to sorted the rate of infiltration increases. Sorted Unsorted Size Sizes (Uniform size) (Mixed) More More runoff infiltration Rate of Precipitation Increased precipitation leads to increased runoff. (puddles) More Rain Less Rain More More Runoff Infiltration  Amount of Vegetation As plant life increases runoff decreases. Lots of plants Very Few Plants More infiltration More runoff ** Plants take in water** Compare and Contrast What will happen to precipitation as it reaches earth's surface? A B Be sure to use the words permeable, porosity, infiltrate, and runoff. C D
