Managing Earth’s Resources

How will the European energy model help the region manage energy resources?

• The model requires they get their energy from many different sources, as opposed to using one main source that can be depleted.

• The model includes sources that are currently being used in high percentages around the world.

• The model only uses nonrenewable resources which makes it easier for them to reach their needed amount of energy.

• The model uses the same amount of energy from every source which ensures each source is depleted equally.

How will the European Union energy plan impact air resources?

• The plan involves using more renewable energy sources, which reduces the amount of energy that people use. Using less energy will lead to fewer emissions entering the atmosphere.

• The plan involves decreasing the use of coal and increasing the use of renewable energy options that don’t emit as many emissions into the atmosphere.

• The plan involves using more renewable energy sources, which improves air quality because using these sources counteract the emissions coal emits into the atmosphere.

• The plan involves changing the energy source being used each week, this improves air quality because different gasses will enter the atmosphere each week.

Which of the following is an advantage of iceberg towing that other solutions, like water recycling, do not have?

• It increases the number of water resources available.

• It limits the use of water.

• It conserves water by reducing the amount used.

• It promotes more efficient use of water.

You are discussing with a friend why South Africa should consider having icebergs towed. Which statement describes the problem this process could help solve?

• Regions around the world are using too much water and icebergs will help reduce the amount of water people are using.

• Regions around the world are experiencing freshwater shortages and icebergs can provide freshwater when they melt.

• Certain areas have water shortages and icebergs will help transfer water from places using a lot of water to places in need of water.

• Certain areas have too much salty ocean water and when icebergs melt in those areas, they will make the oceans less salty.

How has hydraulic fracking affected the production of oil resources in the U.S?

• It has increased the amount of oil the U.S. has produced by using the current oil supply more efficiently.

• It has decreased the amount of oil the U.S. has produced because it has replaced the need for traditional drilling.

• It has increased the amount of oil the U.S. has produced by accessing additional oil sources.

• It has decreased the amount of oil the U.S. has produced because it is a renewable energy source that is easier to access.

What is another environmental benefit of using hydraulic fracking instead of traditional oil drilling?

• Traditional oil drilling has a less negative environmental impact than hydraulic fracking.

• By replacing coal with natural gas, detrimental air emissions and pollutants can be reduced.

• Hydraulic fracking uses more water than conventional gas drilling, so it has a greater negative impact on the environment.

• By replacing coal with natural gas, the amount of electricity generated increases, reducing the cost of electricity.

Is this new drilling method beneficial in terms of water conservation?

• Yes, the method uses a different type of oil that doesn’t produce emissions when burned.

• Yes, this method is an efficient way to reduce unnecessary water usage.

• No, the method requires drilling into rocks that don’t release water into the soil as other drilling methods do.

• No, this method uses large amounts of water and may contaminate other usable water supplies.

Planting trees can be beneficial for the air by (a)   . It is also beneficial for the soil because trees can (b)   . Choose the terms that best complete the sentences.

• absorbing carbon dioxide

• preventing erosion

• providing shade

• producing oxygen

Which statements describe why planting trees is a good conservation method to improve the quality of the environment? Choose two answers.

• A. Trees are susceptible to certain diseases caused by insects and soil contaminants.

• B. Trees help filter the water within the soil.

• C. Trees release oxygen into the atmosphere.

• D. Trees can be beautiful to look at.

Which explains how trees can help increase the family's energy efficiency?

• Trees take up a lot of water through their roots, so they increase the amount of water that is needed in the ground around the house.

• Trees take up a lot of water through their roots, so they help reduce the amount of water that is in the ground around the house.

• Trees can shade the house from the sun and help keep the inside temperature warm when the outside temperature is cold.

• Trees can shade the house from the sun and reduce the amount of energy needed to keep the inside temperature cool when the outside temperature is hot.
