An area experiences a long period of drought forcing towns to pump out almost all of the water held in aquifers. What is the most likely result of this over pumping?

• Stability of underground rock layers will be weakened

• Excessive growth of plants will occur in local lakes

• Rainfall levels will increase and fill the aquifer.

• A dead zone will be created in the watershed.

Which of the following human activities would most likely lead to subsidence, the sinking of the surface of the earth?

• Excess removal of water from underground reservoirs

• Using toxic chemicals in the manufacturing of goods

• Filtering out pollutants at a water treatment plant

• Storing drinking water in small above-ground basins

Which of the following is the most reasonable explanation of why a well drilled into an aquifer would fail to produce water?

• Pollutants have seeped into the groundwater.

• Excessive growth of algae has killed local pond life.

• Over pumping has exceeded rain water replenishment.

• Runoff containing chemicals has caused a dead zone.

Rapid growth of algae in a pond is often the result of -

• loss of habitat due to commercial building.

• flooding that causes water levels to rise.

• excess nutrients from fertilizer runoff.

• clogged river tributaries entering a lake.

Which of the following will most likely increase the amount of erosion that occurs on the banks of a river?
