2. Choose the incorrect statement concerning ground water.

Ground water is useful because it is often plentiful and clean.
It is a good source of water because it can be replenished easily.
Over half of the U.S. population uses it for drinking water.
It is used extensively in agriculture and for industrial purposes.

3. The most important source of ground water is

percolation (seepage) from lakes
percolation from streams and rivers
from rainfall or snow melt.
from underground rivers.

4. The capacity or ability of rock to transmit water is called

porosity.
infiltration.
permeability.
percolation.

5. The capacity or ability of rock to store or hold water is called

porosity.
permeability.
equilibration.
transpiriation.

6. Layers of rock that possess both permeability and

porosity are referred to as aquifers; a good example is clay.
porosity are referred to as aquicludes; a good example is clay.
pore pressure are referred to as artisan; a good example is clay.
porosity are referred to as aquifers; a good example is often sandstone.

7. Ground water interacts with

carbon dioxide to make it acidic and able to effectively dissolve sandstone.
carbon dioxide to make it acidic and able to effectively dissolve limestone.
carbon in the soil to make it acidic and able to effectively dissolve dark minerals
carbon in the soil to make it energetic enough to dissolve iron oxide.

8. Stalagmites are usually composed of

carbonic acid.
sandstone.
limestone.
siltstone.

9. The top of the zone of saturation is also called the

water table which tends to rise under hills and drop under valleys.
water table which tends to rise quickly after a rainstorm and drop just as fast.
capillary fringe which tends to rise quickly after a rainstorm and drop just as fast.
capillary fringe which tends to be flatter than other parts of the zone of saturation.

10. When the water table intersects the surface

an artisan spring forms.
a spring forms.
pollutants enter the aquifer from run-off.
most of the water will evaporate because it is exposed to the atmosphere.

11. Choose the correct statement concerning open and closed aquifers.

An open aquifer is exposed at the surface; a closed aquifer is buried.
An open aquifer has an aquiclude on top; a closed aquifer has an impermeable layer on top.
An open aquifer has a permeable layer on top; a closed aquifer has an impermeable layer on top.
An open aquifer has a permeable layer on top; a closed aquifer has an aquiclude beneath it.

12. Recharging an aquifer is accomplished most readily if the beds above the aquifer are

porous.
permeable.
permeable and porous.
aquicludes.

13. Which is not a typical problem associated with the over pumping of ground water?

sink holes and dry wells.
the lowering of the price of water.
sink holes and sea water infiltration near coasts.
falling water tables and contamination from several sources.

14. One example that minimized ground water contamination in the video was

the use of clay and plastic liners under landfills.
to seal landfills with concrete.
to make sure sewage pipes and tanks did not leak.
the use of liners under some industrial sites to keep the leachate from seeping into the ground.

15. In most areas it would take

decades to resupply the ground water because the infiltration rates are low.
centuries to resupply the ground water because the water table is so deep.
thousands of years to resupply the ground water because the infiltration rates are low.
decades to resupply the ground water because the water table is so deep.
