Example Question #1 : Formation And Uses Of Energy
Based on the graph below from the Energy Information Administration, if the US population wanted to reduce coal consumption which area would potentially have the greatest positive impact?
Electricity
Business
Transportation
Industry
Homes
Electricity
Coal is used in a variety of ways, and the US is reliant on fossil fuels based on the graph above. Mining fossil fuels has an impact on the environment, and they aren't all positive. If the US population wanted to reduce their coal consumption, the area that would potentially have the most significant impact would be the electricity sector. 54% of US electricity is produced using coal. If the US were able to switch to an alternative energy source, the use of coal could be significantly reduced, which may have a positive impact on the environment.
Example Question #5 : Describe How Energy And Fuel Affects The Environment
Coal Power
The typical coal plant in the United States creates more than 125,000 tons of ash and 193,000 tons of sludge each year. On average, 42% of coal combustion waste ponds and landfills are unlined. This means that the substances in the waste can seep into the ground and nearby lakes. Some of the substances include arsenic, mercury, chromium, and cadmium. These can contaminate drinking water supplies and come in direct contact with the consumers who drink water from these areas.
The disposal of coal plant waste has damaged many ecosystems. Once the coal plants have cycled through billions of gallons of water to cool the system, it is dumped back into the river, ocean, or lake it is pulling water from. When this hot water is released back into the body of water, it creates “thermal pollution,” and this can cause harm to the plants and animals living in this area. Many plants add chemicals to their cooling water, so this is released back into the lake, ocean, or river with the hot water.
Based on the information from this article, which part of the environment is affected by coal power plants?
All of the answer choices are correct.
Water Sources
Forests
Air
Water Sources
This article focuses on how coal power plants affect the environment in negative ways. The portion of the environment highlighted in this article are the water sources. The article mentions the warm water being released back into oceans, lakes, or rivers it is pulled from, the potential of chemicals being added back into the bodies of water, and how it can seep into the ground of the water sources.
Example Question #102 : Earth And Space Science
True or False: Fossil fuels primarily have positive impacts on the environment.
True
False
False
The statement in the question is false. Fossil fuels are beneficial to humans and fulfill the needs we have for power, electricity, and industrialization, but it comes at a cost to the environment. Mining and stripping the soil, deforestation, water and air pollution, and loss of animal habitats are just a few of the adverse effects that fossil fuels have on the environment.
Example Question #5 : Describe How Energy And Fuel Affects The Environment
Based on the graph below, which fossil fuel is currently on a decline in usage?
Petroleum
Natural Gas
Biomass
Coal
Coal
Based on the graph provided by the US Energy Information Administration, coal is currently on a decline in usage. Following the black line (representing coal), it can be seen that there is a decrease in use. The other energy type is on increasing in usage.
Example Question #101 : Earth And Space Science
A material that is found in nature and helpful to humans is called a ________________.
natural resource
energy resource
mineral
nutrient resource
natural resource
Humans receive many of our resources from nature, and they are called natural resources. These are things like water, trees, and wind that are naturally occurring, and humans can harness their energy to create power for the everyday things we need. Humans will also mine for resources that are naturally occurring so that we can transform them into other necessary products.
Example Question #2 : Describe How Energy And Fuel Are Created
What does the term "fuel" mean?
Fuel is the burning of a substance.
Fuel is a substance that provides energy as a result of a chemical change.
Fuel is a renewable resource that is beneficial to the environment.
Fuel forms from the remains of ocean organisms.
Fuel is a substance that provides energy as a result of a chemical change.
Fuel is often thought of in terms of gasoline for a car, but it is any substance that provides energy from a chemical change. Food that we eat is turned into energy through our digestive system, so it is also a fuel. Fuel can be for machinery, the body, cars, and other mechanical items. Many of the fuels that we use are nonrenewable and can be harmful to the environment.
Example Question #11 : Formation And Uses Of Energy
Fossil fuels are nonrenewable resources. They are nonrenewable because they take millions of years to form. Earth’s oil took 500 million years to form. Fossil fuels are formed from the remains of organisms. Fossil fuels are rich in energy. Coal is formed from plant remains that have been buried for millions of years. Coal is the fuel used in many electrical power plants. Oil is a thick, black, liquid fossil fuel. Oil forms from the remains of ocean organisms. Petroleum is another name for oil. Natural gas is a mixture of gases. Natural gas forms from the remains of ocean organisms.
How are fossil fuels created?
Cut down from trees and processed
Remains of organisms put under pressure
Harvested from crops and greenhouses
Grown in a laboratory for many years
Remains of organisms put under pressure
Fossil fuels are all created underground or underwater from the remains of organisms. The short passage explains that they are all nonrenewable and take millions of years to form. Coal is from plants, and oil and natural gas are from ocean organisms. All fossil fuels were once a living thing that were placed under immense amounts of pressure over a long period to create the fuel that we need to run our energy and lives.
Example Question #4 : Describe How Energy And Fuel Are Created
Which answer choice lists only renewable energy sources?
Natural gas, oil, petroleum, and solar power
Water, wind, solar, and thermal power
Fossil fuels, wood, water, and wind
Solar power, wind, water, and oil
Water, wind, solar, and thermal power
Renewable resources are created by nature and can be reused or regenerated quickly. They cause very little damage to the Earth and can be a cleaner way to generate the energy we need to live. Wind, water, solar, and thermal power are all products of the Earth and are renewable.
Example Question #5 : Describe How Energy And Fuel Are Created
Which answer choice lists only nonrenewable energy sources?
Wind, thermal, solar, and water
Water, oil, petroleum, and coal
Natural gas, oil, petroleum, and coal
Oil, wind, coal, and natural gas
Natural gas, oil, petroleum, and coal
Nonrenewable energy sources are created when the Earth applies immense amounts of pressure to the remains of organisms buried deep below the surface. The materials must be dug or mined out of the ground and collected to be processed and used. Natural gas, oil, petroleum, and coal are all nonrenewable energy sources that are difficult to replace and will eventually run out.
Example Question #12 : Formation And Uses Of Energy
Fossil fuels are nonrenewable resources. They are nonrenewable because they take millions of years to form. Earth’s oil took 500 million years to develop. Fossil fuels are formed from the remains of organisms. Fossil fuels are rich in energy. Coal is formed from plant remains that have been buried for millions of years. Coal is the fuel used in many electrical power plants. Oil is a thick, black, liquid fossil fuel. Oil forms from the remains of ocean organisms. Petroleum is another name for oil. Natural gas is a mixture of gases. Natural gas forms from the remains of ocean organisms.
