Watercycling

Objective

Describe the water cycle and what happens to precipitation.

Hydrologic Cycle

The Water Cycle1. 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.

Factors that Affect Infiltration1. Permeable2. Unsaturated3. Gentle (flat) slope of land4. Vegetation 5. Land Use6. Rate of precipitation less than

Infiltration

Permeability• Ability to let water through, into.

Permeability

Degree of Saturation

Saturated – full of water; No infiltration; High runoff.

Unsaturated- empty space; High infiltration; Low runoff.

Runoff

Infiltrati

on

Saturation

When soil is saturated water will run over surface; more runoff.

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

Infiltration ____ Runoff ____

Slope _____

Slope (Gradient)• 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

Infiltrati

on

Vegetation

Vegetated-Plants, Trees, Grass absorb water – high infiltration.

Barren-No Vegetation, high runoff

Closure1. 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 As Slope increases Runoff Increases-DirectIncreases-Direct
