Extra Credit Hydrosphere Quiz

In what type of soil would the permeability of groundwater into streams occur the slowest?

• Fine sand

• Gravel

• Fine Clay

• Pebbles

How would several wells in a given area affect the balance of groundwater recharge and discharge?

• The wells would provide dissolved oxygen

• The wells would increase the water table level by adding water from runoff

• The wells would deplete the groundwater which is usually supplied by percolation from rain

• The wells would provide storage areas for groundwater to maintain the water level

When a sewer pipe breaks near a stream which would most likely occur?

• Increase in salinity

• Decrease in dissolved oxygen

• Decrease is dissolved nitrogen

• Increase in pesticides

What process does not remove salt from ocean water?

• precipitation of salt in dry, coastal regions

• evaporation of water in subtropical regions

• sea spray being carried inland by wind

• absorption by marine organisms

What is a drainage basin?

• the channel of a stream

• the land area that contributes water to a river

• the land covered by flood waters

• all streams that flow directly into an ocean

Over 6 billion people on Earth use water every day, yet Earth’s water remains relatively constant. Which statement best explains this phenomenon?

• The sea level is rising due to glacial melt

• Water exists in three phases on the Earth

• Water is constantly recycled by the Water Cycle

• Global warming melts ice needed to replace used water

Runoff from farms containing fertilizers can lead to the following downstream:

• decreased turbidity

• increased velocity

• eutrophication

• increased dissolved oxygen

When will surface runoff occur?

• When the precipitation rate is greater than the infiltration rate.

• When the infiltration rate is greater than the precipitation rate.

• When the precipitation rate is less than the infiltration rate.

• When the precipitation rate is equal to the infiltration rate.

Which consequence could an exponentially growing human population have on drinkable water?

• Decrease in the amount of waste and pollutants in the water.

• Decrease in needing water.

• Increase in the amount of water.

• Increase in the cases of waterborne diseases.

Study the graph below.  Where is most of the Earth's water located?

• Rivers and Lakes
• Glaciers and Icecaps
• oceans
• groundwater
