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
