Natural Resources Summative Study Guide

Environmental groups are constantly looking for new and better ways to conserve. Which is not a conservation technique?

• Save up chemicals and dump all together into landfill.

• Use less gasoline, coal, and natural gas.

• Set thermostats lower in winter and higher in summer.

• Use solar panels for electricity.

During heavy rains, landslides cause severe damage to roads and houses in mountainous regions. Which solution can help reduce damage from landslides?

• People should build more houses in mountainous regions.

• Houses in mountainous regions should be empty during heavy rains.

• More trees should be planted to stop the mass movement of rocks and soil.

• Houses should be built using wood rather than concrete.

Strong tides, waves, and human activities all contribute to coastline erosion. Local governments build structures like groins and seawalls to prevent erosion of the coastlines. However, it has been observed that these structures cause negative effects on the coastlines. What other step can local governments take to restore beaches?

• Reduce the number of harbors to control the erosion along coastlines.

• Increase human settlement around beaches to reduce pollution and erosion.

• Allow more frequent boating along coastlines to reduce erosion.

• Initiate programs where beaches are replenished with sand and sediments.

During a heavy rain, water collects behind a flood control dam. What happens to the collected water?

• The water is all used for drinking.

• The water is hauled away by trucks.

• The water is held until it all evaporates.

• The water is slowly released to the watershed.

How do levees help prevent a river from flooding towns?

• Levees make the river wider.

• Levees make the river narrower.

• Levees make the riverbanks taller.

• Levees make the riverbanks shorter.

Researchers claim that building dams on rivers causes soil erosion. Which statement correctly analyzes the claim given by the researchers?

• The claim is correct; the construction of dams causes loss of vegetation, and this leads to soil erosion.

• The claim is incorrect; the dams prevent flooding, and this reduces the risk of soil erosion by surface runoff.

• The claim is incorrect; the dams increase the speed of water, and this does not support the transport of sediments.

• The claim is correct; the dams hold sediments found in the river, and this causes the river to erode its banks in order to compensate for the loss of sediments.

A scientist researching sea kelp found that sugar kelp can be used to produce fuel. The scientist made a paste of the sugar kelp by mixing it with water and heating it to a high temperature. He found that this resulted in the formation of oil. How will this research be useful?

• It could reduce the dependence on fossil fuels.

• It will increase the production of fossil fuels.

• It will reduce the cost of fossil fuel production.

• It could improve the quality of fossil fuel produced.

Which of the hints given is not one of the “Three R’s” of conservation?

• Wash and reuse plastic bottles.

• Rotate types of fossil fuels used.

• Reduce use of gasoline and oil.

• Collect and recycle aluminum cans.

The U.S. Energy Information Administration published the given data that shows the breakdown of electricity generation by various natural resources in the United States in 2009. What would be the effects of increasing energy generation by wind and geothermal sources?

• It would decrease nonrenewable energy resources and increase air pollution.

• It would conserve nonrenewable energy resources and decrease air pollution.

• It would decrease renewable energy resources and decrease air pollution.

• It would conserve renewable energy resources and increase air pollution.
