Fossil Fuel and Alternative Energy

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

• refineries.
• reserves.
• fuels.
• fertilizers.

The three major fossil fuels are coal, oil, and

• natural gas.
• uranium.
• wood.
• electricity.

Fossil fuels are energy-rich because they contain

• heat.
• fossil fragments.
• electricity.
• hydrocarbons.

What is the result of using fossil fuels more rapidly than they are formed?

• The reserves will be refilled more quickly.
• The reserves will eventually be used up.
• The price of fossil fuels will fall.
• The reserves will not be affected.

Coal is a solid fossil fuel formed from

• hardened lava.
• the remains of animals.
• decaying plant remains.
• rocks.

The most plentiful fossil fuel in the United States is

• natural gas.
• coal.
• oil
• wood.

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

• incinerators.
• deposits.
• reserves.
• refineries.

Fossil fuels are made of energy-rich chemical compounds called

• hydrocarbons.
• fossil fuel.
• biomass fuel.
• petrochemicals.

A liquid fossil fuel formed from the remains of animals, algae, and other organisms is

• petroleum.
• coal.
• natural gas.
• hydrocarbon.

Which of the energy sources shown are NOT fossil fuels?

• Petroleum
• Natural Gas
• Coal
