• A lack of PRECIPITATION will DECREASE the water table • An increase

What determines the changing level of our water table?

Porosity – the percentage of pore space • Water is found in the pores

• The more pores there are, the more water can be held

1. Shape of Particle A ANGULAR FITS CLOSER ROUND DOESN’T FIT CLOSE Low Porosity

2. Packing • CLOSER = LESS SPACE • FARTHER = MORE SPACE Higher Porosity

3. Sorting A Well Sorted Unsorted High Porosity Low Porosity B

• The total porosity will be equal if they have the same shape

AIM: WHAT IS WEDGL? ? ? DO NOW: 1. TAKE A VOCAB 2. IF YOU NEED TO MAKE UP THE TEST BE READY NOW! IF YOU HAVE BOTH PARTS TO MAKE UP I WILL SEE YOU AT LUNCH TODAY =( HW: 1. VOCAB part 1 DUE FRIDAY 2. CHECK HW CALENDAR

What is the purpose of a shed in your backyard?

The World’s Water Supply • 97% of Earth’s water is SALT water • 3% is FRESH water

2% is confined to ice and glaciers That only leaves 1% of all the water on Earth available for humans to use!

LOOK AT THE PICTURE ON THE SIDE BOARD……. .

How is Water Recycled? • The water cycle - water circulates between the hydrosphere (water) and atmosphere (air)

Water evaporates fastest when there are… 1. WARM TEMPERATURES 2. FAST WINDS

3. HIGH SURFACE AREA 4. DRY AIR (low humidity)

AIM: GROUNDWATER ACTIVITY (PERIOD 2 AND 7) DO NOW: 1. TAKE OUT LAB # 26 2. SIT QUIETLY AND WAIT FOR INSTRUCTION =) HW: 1. LAB #27 DUE MONDAY 2. VOCAB PART 1 DUE TOMORROW 3. GROUNDWATER REVIEW QUESTIONS DUE MONDAY

AIM: What is permeability? DO NOW: 1. Which container will allow water to flow through faster? Which container has a greater total porosity? Which will retain more water? HW: 1. LAB #27 DUE MONDAY 2. VOCAB PART 1 DUE TOMORROW 3. GROUNDWATER REVIEW QUESTIONS DUE MONDAY

1. Infer why water will get stuck traveling through column D. 2. Determine what will happen to the rate of the water as it travels through the other columns.

What conditions allow for infiltration of water into ground? • Unsaturated – empty (not already filled with water) • Gentle Slope – so water is able to seep in

• Permeable – ground must have open pore spaces (porosity) to allow water to pass through (pavement or black top are not permeable. )

• Water will infiltrate when the ground is flat and permeable

AIM: REVIEW OF GROUNDWATER DO NOW: 1. TAKE OUT VOCAB HW: 1. LAB # 27 DUE MONDAY 2. GROUNDWATER REVIEW QUESTIONS DUE MONDAY

What is permeability? • The rate at which groundwater will infiltrate the rock and sediments • Bigger pore spaces = faster permeability

WHAT HAPPENS IF THE WATER CANT PERMEAT INTO THE GROUND FAST ENOUGH?

Runoff

What conditions cause Runoff? 1. Ground is frozen (not permeable)

2. Soil is already fully saturated with water 3. Rainfall exceeds the rate of infiltration

4. The slope of the land is steep 5. Vegetation of area has been stripped away

Why does the water travel upward through the paper towel?

Capillary Action • The upward movement of water against gravity

• Occurs because water is sticky –(positive Hydrogen's and negative Oxygen attract) • The smaller the pores, the higher the water rises

WHERE IS THE ZONE OF SATURATION IN THIS DIAGRAM? WHAT COULD CAUSE THE ZONE OF SATURATION TO INCREASE IN HEIGHT?

What is the water table? • The level of stored water within rock and sediments underneath us. • Where the zone of saturation meets the zone of aeration.
