Water Movement

Look at the diagram of a stream with toxic chemicals flowing into it.

This diagram models how toxic runoff can pollute a stream and also

• produce acid rain.

• cause soil erosion.

• create algae blooms.

• pollute groundwater.

The graph shows water table levels in an aquifer changing over a period of time.

Which MOST likely caused the changes observed in the data over time?

• increase in the amount of precipitation

• increase in water conservation efforts

• decrease in the amount of recharge

• decrease in irrigation for farming

Virginia’s Valley and Ridge province has many limestone and dolomite rock layers. How could the composition of these layers affect the groundwater stored in the aquifer in this province?

• Over time, acidic water could dissolve the rock, creating larger spaces and increasing the volume of groundwater storage.

• Over time, acidic water could dissolve the rock, collapsing spaces and decreasing the volume of groundwater storage.

• Over time, acidic water could leach toxins from the rock, contaminating the water and making it unusable.

• Over time, acidic water could leach ions from the rock, decreasing the pH of the water and making it more drinkable.

The figure shows many of the components of a typical watershed.

Which of the following would happen if precipitation increased within the watershed boundary?

• The water table would rise.

• Some tributaries would disappear.

• Hillside infiltration would be reduced.

• Boundaries of the watershed would expand.

A rural, forested area receives a lot of rain in a short amount of time. What would most likely cause potential flooding in the area?

• if the area has a large uncharged aquifer beneath it

• if the water level in the area is below the zone of saturation

• if the ground of the area is already saturated with water

• if the ground of the area is mostly sandy soil
