1. Do Now Begin DO NOW Word Match Watercycling

2. Objective Describe the water cycle and what happens to precipitation.

3. Hydrologic Cycle

4. 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.

5. 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.

8. Think about factors that will allow water to INFILTRATE

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

14. Capillary Fringe

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

17. DESCRIBE THE FACTORS THAT AFFECT RUNOFF AND INFILTRATION OF WATER? INVESTIGATING GROUNDWATER ANIMATION http://earthguide.ucsd.edu/earthguide/diagrams/groundwater/index.ht ml

18. Define the Vocabulary & Label

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

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

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

22. Runoff Infiltration Saturation When soil is saturated water will run over surface; more runoff.

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

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

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

26. Vegetation affects infiltration Vegetation increases, infiltration increases.

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

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