Objective Describe the water cycle and what happens to precipitation.

Hydrologic Cycle

The Water Cycle 1. Evaporation: Water from oceans, lakes and rivers turns to gas, enters the atmosphere. 2. Transpiration: Water released by plants and trees into the atmosphere. 3. Condensation: Water vapor cools to dewpoint and becomes liquid water.

What Happens to Precipitation? 4. Precipitation: Falling liquid or solid water from clouds. Rain, Snow, Sleet, Hail. 5. Runoff: Flows over land on the surface into streams, rivers, oceans. . . 6. Infiltration: Seeps into the soil.

GROUNDWATER QUIZ BRAINPOP AIM: What happens to water when it infiltrates the ground?

Think about factors that will allow water to INFILTRATE

Fill in the handout: Vocabulary: Zone of Aeration. Water Table. Capillary Fringe-

Capillary Fringe

Zone of Saturation. Bedrock. Water tables come to earth’s surface at: Water tables typically follow the topography of the land.

1. 2. 3. 4. 5. 6. Factors that Affect Infiltration Permeable Unsaturated Gentle (flat) slope of land Vegetation Land Use Rate of precipitation less than Infiltration

Permeability Infiltration • Ability to let water through, into. [ Infiltration ] Permeability

Degree of Saturation Saturated – full of water; No infiltration; High runoff. Unsaturated- empty space; High infiltration; Low runoff.

Runoff soil is saturated water will run over surface; more runoff. Infiltration n When Saturatio n

Slope of the land • Flat Slope=High Infiltration= Low Runoff • Steep Slope=Low Infiltration=High Runoff Infiltration ____ Runoff ____ Slope _____

Slope (Gradient) Infiltration • Steeper slope = less infiltration. • Slope ____ Infiltration ____ Slope

Land use affects infiltration • Parking lots, paved roads and buildings prevent infiltration into the ground. • Farmland also reduces infiltration. • Less infiltration = More Runoff.

Vegetation affects infiltration • Vegetation increases, infiltration increases�.

Vegetation Trees, Grass absorb water – high infiltration. n Barren-No Vegetation, high runoff Infiltration n Vegetated-Plants, Vegetation

Closure 1. Rainfall is most likely to infiltrate into soil that is Flat, unsaturated, vegetated, large particles. 2. Draw the relationship between slope of the land runoff As Slope increases Runoff Increases-Direct 3. Flooding is likely to occur if the soil surface is Saturated, Paved, Impermeable, Steep
