1)Human populations all over the world burn fossil fuels to power cars, planes, and generate electricity. Select the statement that best describes the long-term global effects of this behavior. (2 points)

A) Burning fossil fuels pollutes the environment and our heavy reliance on them creates a long-term problem because they are not a renewable resource.

B) Countries will not need to spend money on investigating other sources of energy because fossil fuels are abundant.

C) Fossil fuels burn clean so the pollution problem is not really a source of concern for the future.
D) As populations increase, the need for fossil fuels will decrease; therefore, there will always be an abundance.

2)Desalinization plants remove the salt from sea water and make it usable for drinking and irrigation. Review the following statements and select the one that best describes how this technology has had a positive impact on the environment. (2 points)

A)Desalinization plants are expensive to build and maintain; however, on some small islands, where there is no fresh water, they provide water to those who need it. Without these plants people were dependent on capturing rainwater in order to survive. In times of drought, when there was not enough rain, people used to have to buy water that was imported from other areas.

B)Of all the water on Earth, 97% is salt water, 3% is fresh water and much of this is locked up in ice. All living things need fresh water to survive. As populations grow, the demand for fresh water will increase. If humans can use desalinization plants to make the fresh water they need, more fresh water will be available for the plants and animals that need it.

C)Some islands in the Caribbean do not have any fresh water. This has limited growth on these islands. Building a desalinization plant could provide jobs for the local people. This can make the economy on these islands more stable.

D)Some areas by the coast are very remote and far from fresh water supplies. These areas are great places to build vacation resorts. These resorts use desalinization plants to provide their guests with fresh water. Desalinization plants will allow for more resorts to be built in remote areas along the coast.

A)coal

B)natural gas

C)nuclear

D)petroleum.

4)In an attempt to reduce our dependence on non-renewable resources, and cut down on the harm to the environment, we could burn ______ to produce electricity. (2 points)

A) biomass

B) coal

C) natural gas

D) petroleum

5)In the United States, most of our energy comes from this non-renewable resource, which has a negative effect on the environment. (2 points)
A) coal
B) nuclear
C) natural gas
D) petroleum

6)One alternative to burning non-renewable fuels, which harm the environment, could be to burn (2 points)
A) biomass

B) coal

C) natural gas

D) petroleum

7) The city is thinking about starting a program to add a new chemical to the public pool. Before they do, they want to find out if there are any health risks associated with this type of chemical. Which group would be the best to advise them on this topic? (2 points)
A)a group of concerned citizens who oppose the program
B)the company that manufactures the chemical
C)the local pest pool companies who would be hired to take care of the pool
D)the government agency that regulates these types of chemicals

8)The hybrid car uses battery power and gasoline to power the vehicle. This means that less gasoline is burned to power the vehicle. When burned, gasoline emits pollutants into the air. Evaluate the statements and choose the statement that best describes how this technology benefits the environment. (2 points)
A)Electricity is cheaper than gas; hybrid cars use more electricity generated by the battery they carry. Therefore, hybrid cars will save people money in fuel costs.
B)Gasoline is a nonrenewable resource that, when burned, produces pollution that can harm the environment; therefore, because hybrid cars emit less pollution than regular cars, they do not cause as much damage to the environment.
C) Hybrid cars are becoming more popular all the time. This means that sales of hybrid cars are going up. When sales go up, this creates jobs for people in our country and beyond.
D) Hybrid cars run totally on a renewable resource. This means that as these cars become more popular, we will decrease our dependence on oil. Using less oil will reduce the amount of certain pollutants in the environment.

9)Whenever possible, these types of power plants should be built because they generate virtually no pollution. (2 points)
A) biomass power plants
B) geothermal power plants
C) nuclear power plants
D) natural gas power plants

Most importantly the fossil fuels produce toxic substances and pollutants like carbon dioxide, nitrogen oxide, sulfur dioxide etc. These pollutants pollute our atmosphere at a greater extent, and it is the measure cause for global warming. They have a long term effect on our ecosystem.

2.The correct answer for above statement is:

B)Of all the water on Earth, 97% is salt water, 3% is fresh water and much of this is locked up in ice. All living things need fresh water to survive. As populations grow, the demand for fresh water will increase. If humans can use desalinization plants to make the fresh water they need, more fresh water will be available for the plants and animals that need it.

Explanation:

The replacement of salt or other chemicals from something, such as seawater or soil is desalinization. Desalinization can be achieved by means of evaporation, freezing, reverse osmosis, ion exchange, and electrodialysis.

3 The correct answer for above statement is:

A)coal

Explanation:

Monopolies buy more than 90% of the coal utilized in the United States. Coal has been used to generate electricity in the United States because an Edison plant was developed in New York City in 1882.

4.The correct answer for above statement is:

A) biomass

Explanation:

In an effort to reduce our dependence on non“renewable resources, and cut down on the abuse to the environment, we could burn biomass to generate electricity. Biomass fuels come from natural elements like wood products, dehydrated vegetation, crop debris, aquatic plants, and still trash.

5.The correct answer for above statement is:

A) coal

Explanation:

Whenever it is fired, gases are carried off and particles of ash, called "fly ash," are printed. The sulfur in coal blends with oxygen to produce sulfur dioxide, which can be an important source of air pollution is released in large enough amounts.

6.The correct answer for above statement is:

A) biomass

Explanation:

The biomass can be used to reduce the effect of foosil fuel burning on environment and can be helpful to ruduce pollution.

7.The correct answer for above statement is:

D)the government agency that regulates these types of chemicals

Explanation:

Under a broad range of federal statutes, EPA assumes health, safety, and vulnerability data wants necessary testing and controls human and environmental performances for different chemical materials and mixtures.

8.The correct answer for above statement is:

B)Gasoline is a nonrenewable resource that, when burned, produces pollution that can harm the environment; therefore, because hybrid cars emit less pollution than regular cars, they do not cause as much damage to the environment.

Explanation:

Even though hybrids still provide some emissions, studies show that gasoline-powered vehicles are yet producing up to 50% more pollutants than hybrids and EVs. Overall, these cars are issuing fewer pollutants than gasoline-powered transports and the power plants generating electricity to accredit them.

9.The correct answer for above statement is:

C) nuclear power plants

Explanation:

Nuclear power reactors do not generate direct carbon dioxide emissions. Unlike fossil fuel-fired energy plants, nuclear reactors do not create air contamination or carbon dioxide while operating. However, the means for drilling and refining uranium ore and producing reactor fuel all want large quantities of energy.
