Groundwater

Process A is...

• Evaporation

• Precipitation

• Transpiration

• Infiltration

The amount of runoff at Y will increase if the...

• slope of the land decreases

• porosity of the soil increases

• evaporation rate exceeds the infiltration rate

• precipitation rate exceeds the infiltration rate

Which of these situations would decrease the amount of runoff in a certain area?

• Increasing the amount of vegetation

• Increasing the slope

• Paving over grassy areas

• Increasing the amount of precipitation

The water table will rise closer to the surface if....

• There is a long drought

• More people move into this area

• The amount of precipitation increases

• The amount of vegetation increases

Porosity means....

• How fast water infiltrates

• How much space there is between particles in the ground

• How much water is retained by particles in the ground

• How much water stays on the surface

The volume of soil particles in each beaker is the same. Which beaker has the greatest porosity?

• Beaker A

• Beaker B

• Beaker C

• They are all the same

Permeability means...

• How much space there is between particles in the ground

• How much water sticks onto particles in the ground

• How fast water infiltrates through the ground

• How much water is retained in the ground

Which beaker has the highest permeability?

• Beaker A

• Beaker B

• Beaker C

• They are all the same.

CHOOSE TWO: Capillarity means....

• The amount of water retained as it infiltrates

• The speed that water infiltrates through the ground

• The amount of space between particles in the ground

• The amount of water that sticks to particles in the ground

• The time it takes for water to infiltrate through the ground

Which beaker has the highest capillarity?

• Beaker A

• Beaker B

• Beaker C

• They are all the same
