Ch.9 Energy Resources Practice Test

Fossil fuels are considered to be ​ (a)   because they take hundreds of millions of years to form and they may eventually run out.

• nonrenewable

• renewable

• efficient

• nuclear

Answer explanation

Fossil fuels are classified as nonrenewable resources because they require hundreds of millions of years to form and are finite, meaning they can eventually be depleted.

The three major fossil fuels are

• Coal

• Solar

• Oil

• Hydroelectric

• Natrual Gas

Answer explanation

The three major fossil fuels are coal, oil, and natural gas. Solar and hydroelectric are renewable energy sources, not fossil fuels.

Fossil fuels are energy-rich because they contain

• sugar

• hydrocarbons

• radioactivity

• fossil fragments

Answer explanation

Fossil fuels are energy-rich because they contain hydrocarbons, which are organic compounds made of hydrogen and carbon. These compounds store energy that can be released when burned, making hydrocarbons the correct choice.

​ (a)   is most plentiful fossil fuel in the United States. 

• Coal

• Natural Gas

• Oil

• Water

Answer explanation

Coal is the most plentiful fossil fuel in the United States, with significant reserves compared to natural gas and oil. It has been a primary energy source for electricity generation and industrial processes.

What is the solid fossil fuel formed from the decaying plant remains?

• oil

• coal

• natural gas

• biomass

Answer explanation

Coal is the solid fossil fuel formed from the decaying remains of plants over millions of years, making it the correct answer. Oil and natural gas are derived from marine organisms, while biomass refers to organic material used for energy.

What is the thick, black, liquid fossil fuel formed from the decaying animal remains?

• coal

• oil

• natural gas

• biomass

Answer explanation

The thick, black, liquid fossil fuel formed from decaying animal remains is known as oil. Unlike coal, which is solid, and natural gas, which is gaseous, oil is specifically a liquid fossil fuel.

Which fossil fuel produces the lowest levels of most air pollutants?

• coal

• oil

• natural gas

• petroleum

Answer explanation

Natural gas produces the lowest levels of most air pollutants compared to coal, oil, and petroleum. Its combustion results in fewer emissions of sulfur dioxide, nitrogen oxides, and particulate matter.

Factories where crude oil is separated into fuels and other products are called

• incinerators

• deosits

• reserves

• refineries

Answer explanation

Factories that process crude oil to separate it into fuels and other products are known as refineries. They play a crucial role in the oil industry by converting raw crude into usable products.

Substances that provide energy as the result of a chemical change are called

• fertilizers

• fuels

• reserves

• refineries

Answer explanation

Fuels are substances that release energy through chemical changes, such as combustion. Unlike fertilizers, reserves, and refineries, fuels specifically provide energy, making them the correct choice.

The process of burning a fuel to change chemical energy into thermal energy is called

• nuclear fission

• nuclear fussion

• combustion

• electricity

Answer explanation

The process of burning a fuel to convert chemical energy into thermal energy is known as combustion. This process releases heat and is fundamental in engines and heating systems.
