Ecology SOL Unit 8.1- Energy Sources

What are the TWO main types of energy sources?

• Renewable

• Nonrenewable

• Biorenewable

• Geothermal

Answer explanation

The two main types of energy sources are Renewable and Nonrenewable. Renewable sources, like solar and wind, can be replenished, while Nonrenewable sources, like fossil fuels, are finite and will deplete over time.

Which of the following are true about Nuclear Energy? Select THREE answers.

• It can be generated by fusion or fission processes.

• The waste is difficult to dispose of.

• It is a fossil fuel.

Answer explanation

Nuclear energy can be generated through fusion or fission processes, which are the splitting or combining of atomic nuclei. Additionally, the waste produced from nuclear energy is challenging to dispose of safely.

Which of the following are the THREE types of fossil fuels?

• Petroleum

• Coal

• Natural Gas

• Nuclear Energy

Answer explanation

The three types of fossil fuels are Petroleum, Coal, and Natural Gas. These are natural resources formed from the remains of ancient organisms, while Nuclear Energy is not a fossil fuel.

Which energy source is harnessed by burning organic waste?

• Biomass Energy

• Solar Energy

• Wind Energy

• Geothermal Energy

Answer explanation

Biomass energy is produced by burning organic waste, which releases stored energy. This process converts the waste into usable energy, making biomass a renewable energy source.

Which type of energy is considered sustainable because it is naturally replenished?

• Renewable Energy

• Nonrenewable Energy

• Nuclear Energy

• Fossil Fuels

Answer explanation

Renewable energy is sustainable because it is naturally replenished, unlike nonrenewable energy sources like fossil fuels and nuclear energy, which deplete over time.

Which fossil fuel is mostly made up of methane?

• Natural Gas

• Coal

• Petroleum

• Biomass

Answer explanation

Natural gas is primarily composed of methane (CH4), making it the correct answer. In contrast, coal and petroleum contain more complex hydrocarbons, while biomass is derived from organic materials.

Which energy source is NOT burned to produce energy?

• Nuclear Energy

• Coal

• Natural Gas

• Biomass

Answer explanation

Nuclear energy is produced through nuclear reactions, not by burning. In contrast, coal, natural gas, and biomass are all burned to release energy.

Which energy source is considered clean and produces less pollution?

• Renewable Energy

• Nonrenewable Energy

• Fossil Fuels

• Nuclear Energy

Answer explanation

Renewable energy sources, such as solar and wind, are considered clean because they produce little to no pollution compared to nonrenewable sources like fossil fuels, which emit harmful greenhouse gases.

Which energy source is considered the cleanest of all nonrenewable energy sources?

• Coal

• Natural Gas

• Petroleum

• Nuclear Energy

Answer explanation

Nuclear energy is considered the cleanest nonrenewable energy source because it produces minimal greenhouse gas emissions during operation, unlike coal, natural gas, and petroleum, which release significant pollutants.

What is a disadvantage of using coal and other fossil fuels as energy sources?

• It is difficult to extract.

• It releases toxic gases and pollutants.

• It is renewable.

• It is the cleanest energy source.

Answer explanation

A major disadvantage of using coal and other fossil fuels is that they release toxic gases and pollutants into the atmosphere, contributing to air pollution and health issues, unlike renewable energy sources.
