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.
<h2>2.The correct answer for above statement is:</h2><h3>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.</h3><h3>Explanation:</h3>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.
<h2>3 The correct answer for above statement is:</h2><h2>A)coal</h2><h3>Explanation:</h3>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.
<h2>4.The correct answer for above statement is:</h2><h2>A) biomass</h2><h3>Explanation:</h3>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.
<h2>5.The correct answer for above statement is:</h2><h2>A) coal</h2><h3>Explanation:</h3>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.
<h2>6.The correct answer for above statement is:</h2><h3>A) biomass</h3><h3>Explanation:</h3>The biomass can be used to reduce the effect of foosil fuel burning on environment and can be helpful to ruduce pollution.
<h2>7.The correct answer for above statement is:</h2><h3>D)the government agency that regulates these types of chemicals</h3><h3>Explanation:</h3>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.
<h2>8.The correct answer for above statement is:</h2><h3>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.</h3><h3>Explanation:</h3>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.
<h2>9.The correct answer for above statement is:</h2><h3>C) nuclear power plants</h3><h3>Explanation:</h3>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.
