Georgia has a lot of potential to produce power from renewable resources. About two-thirds of Georgia is forested. What type of renewable resource could Georgia most likely produce from the forests?
Georgia could most likely produce biomass energy from its forests. This involves using wood, wood waste, and other organic materials to generate electricity or heat. Georgia is already home to several biomass plants and could continue to expand its use of this renewable energy source.
Geothermal energy is a type of energy that harnesses Earth's interior heat. It is obtained by digging deep wells and pumping heated underground water or steam to the surface. It is used worldwide to heat homes and businesses and to make electricity. Which statement supports the claim that geothermal energy is considered a renewable resource?
Geothermal energy is considered a renewable resource because Earth's interior heat is constantly being generated by natural processes such as radioactive decay and mantle convection, meaning that the heat source will not run out or be depleted in the foreseeable future.
Rare earth metals are rarely found in large quantities on Earth. Instead, they are spread very thinly throughout Earth's crust, making them very difficult to get. Once they are all used, they are gone forever. Which energy resource is similar to rare Earth metals in that once it is used up, it is gone?
Fossil fuels such as coal, oil, and natural gas are similar to rare Earth metals in the sense that once they are consumed and cannot be replaced or regenerated at the rate at which they are being consumed. Unlike renewable energy resources, fossil fuels are finite resources and their reserves are being depleted with continued usage.
What could humans do to decrease soil erosion?
a develop land for agriculture
b plant more cover crops
c cut down forests for logging
d allow farm animals to overgraze
The most effective action that humans could take to decrease soil erosion is to plant more cover crops. Cover crops help to protect soil from erosion by reducing the impact of heavy rain and wind on the soil, adding organic matter to the soil, and preventing the growth of weeds that may contribute to soil erosion. Developing land for agriculture, cutting down forests for logging, and allowing farm animals to overgraze are all activities that can increase soil erosion and should be avoided or managed carefully to prevent widespread erosion.
Which statement gives the best explanation about what will happen to the global oil reserves as time goes on?
a The global oil reserves will turn into alternative forms of fuel.
b The global oil reserves will continue to increase.
c The global oil reserves will remain relatively steady.
d The global oil reserves will continue to decrease.
The best explanation about what will happen to the global oil reserves as time goes on is that they will continue to decrease. Oil is a non-renewable resource, which means that it is formed much more slowly than it is being used. As a result, the reserves are being depleted much faster than new ones are being formed. While it is possible that alternative forms of fuel may become more widely used in the future, it is highly unlikely that these new sources will be able to fully replace oil in the near future, and the depletion of oil reserves will likely continue.
Which of the following is NOT a method of limiting soil erosion on farmland?
a contour plowing
b terracing
c crop rotation
d overgrazing
Overgrazing is not a method of limiting soil erosion on farmland, rather it is a practice that can contribute to soil erosion. Overgrazing occurs when too many animals are allowed to graze on a particular area of land, resulting in vegetation and root systems being removed, leaving the soil exposed and susceptible to erosion from rainfall and wind. The other options, contour plowing, terracing, and crop rotation, are all methods of limiting soil erosion and are used to help preserve soil quality and prevent runoff.
What can all non-renewable resources theoretically be?
a converted to nonmetallic minerals
b exhausted or depleted
c converted to renewable ones
d recycled or reused
All non-renewable resources can theoretically be exhausted or depleted. Non-renewable resources are finite resources, meaning they exist in a limited amount and cannot be replenished at a rate that keeps up with their consumption. When non-renewable resources are extracted and used, they cannot be replaced, and if they are not used responsibly, they can be depleted, leaving none for future generations. While it is possible to recycle or reuse certain non-renewable resources like metals, they will eventually become too scarce or too expensive to obtain and use.
Which of the following best explains why conserving resources is important?
a There are a limited amount of resources on Earth, so conserving them will make them last longer.
b Humans need to learn how to make the resources faster, so conserving them gives them a chance to learn how.
c There are too many resources on Earth, so conserving them helps to create more space for humans to build cities.
d Humans require resources, so conserving them helps make sure they are replaced when they are used.
The best explanation as to why conserving resources is important is that there are a limited amount of resources on Earth, so conserving them will make them last longer. This is because many natural resources are non-renewable and can be depleted over time if they are not used responsibly or sustainably. By conserving resources, we can reduce our overall consumption and help to ensure that there will be enough resources available for future generations. Additionally, resource conservation can also help to reduce our impact on the environment by limiting the amount of energy and resources needed for resource extraction, transportation, and processing.
Which action can help to reduce the amount of waste in a landfill?
a riding a bicycle
b planting more trees
c recycling aluminum cans
d taking shorter showers
Recycling aluminum cans is an action that can help to reduce the amount of waste in a landfill. Aluminum is a non-renewable resource, and recycling aluminum cans not only reduces the amount of waste going into landfills but also conserves natural resources and energy. When aluminum cans are recycled, they can be melted down and used to create new cans, reducing the need for new aluminum extraction and processing. Riding a bicycle, planting more trees, and taking shorter showers are all actions that can help to reduce our impact on the environment but are not directly tied to reducing waste in landfills.

What would be the best question to ask in order to immediately determine whether or not an energy resource is renewable?
a
How long until it runs out?
b
How many people use it?
c
How much energy does it produce?
d
How long has it been used?
a. "How long until it runs out?" would be the best question to ask in order to immediately determine whether or not an energy resource is renewable. Renewable energy resources are those that are replenished naturally and continuously, meaning that they have a virtually unlimited supply. Non-renewable resources, on the other hand, are finite resources that exist in a limited amount and cannot be replenished at a rate that keeps up with their consumption. By asking this question, it is possible to quickly determine if an energy resource is renewable or non-renewable.
Loss of topsoil may lead to the pollution of rivers and streams by
a
decreasing nutrients.
b
decreasing erosion.
c
increasing cropland.
d
increasing runoff.
d. Increasing runoff. Loss of topsoil can lead to the pollution of rivers and streams because as topsoil is eroded, it can carry with it sediment, pesticides, fertilizers, and other pollutants. These pollutants can then enter nearby water bodies, causing problems such as increased turbidity, reduced oxygen levels, and harm to aquatic organisms. Additionally, increased runoff can cause flooding and soil degradation in downstream areas. Therefore, it is important to conserve topsoil and manage agricultural and land use practices to prevent excessive erosion and runoff.

Which of the following is the best way to reduce the need for additional energy consumption?
a
remediation
b
preservation
c
reservation
d
conservation
d. Conservation is the best way to reduce the need for additional energy consumption. Conservation involves using resources efficiently and responsibly, reducing waste, and minimizing energy consumption. By conserving energy, we can reduce our overall demand for energy and decrease our impact on the environment. Remediation refers to the process of cleaning up environmental pollution, while preservation and reservation generally refer to protecting natural areas or resources from development or use. While these activities may help to protect the environment, they do not directly address the issue of reducing energy consumption.
Todd's teacher told him that the gas used to power cars is a natural resource and would run out in the future. What is one way Todd could help to conserve this natural resource?
a
Todd could try to dig in his backyard to find more natural gas.
b
Todd could put water into the car's gas tank instead of gas.
c
Todd could put less gas in the gas tank each time he fills it up.
d
Todd could use a car powered by electricity instead of gas.
d. Todd could use a car powered by electricity instead of gas. This is one way Todd could help to conserve the natural resource of gas used to power cars. Electric cars are powered by electricity, which can come from renewable sources like solar, wind, or hydroelectric power, unlike gasoline-powered cars. By using an electric car instead of a gas-powered car, Todd could help to reduce his overall demand for gasoline and minimize his environmental impact. Digging in his backyard to find more natural gas is not a viable solution, and putting water into the gas tank or reducing the amount of gas used will cause the car to malfunction and should be avoided.
Geothermal energy is a type of energy that harnesses Earth's interior heat. It is obtained by digging deep wells and pumping heated underground water or steam to the surface. It is used worldwide to heat homes and businesses and to make electricity. Which statement supports the claim that geothermal energy is considered a renewable resource?
a
Geothermal energy can be used continuously.
b
Geothermal energy is not quickly replenishable.
c
Geothermal energy is a naturally available resource.
d
Geothermal energy cannot be used to create electricity.
a. The statement that supports the claim that geothermal energy is considered a renewable resource is "Geothermal energy can be used continuously." Geothermal energy is considered a renewable resource because Earth's interior heat is constantly being generated by natural processes such as radioactive decay and mantle convection, meaning that the heat source will not run out or be depleted in the foreseeable future. The fact that geothermal energy can be used continuously (as long as it is managed responsibly to prevent overuse) demonstrates its renewable character.
