Fossil Fuels: Use

Fossil fuels are derived from ancient organic materials and are used for various energy needs, including electricity generation. They are a dominant energy source due to their availability but have significant drawbacks, such as greenhouse gas emissions and extraction challenges. Fossil fuels are non-renewable, taking millions of years to form, and current reserves are depleting rapidly, posing a risk of running out within our lifetime.

What are fossil fuels primarily composed of?

• Compressed prehistoric organic material

• Minerals and metals

• Synthetic chemicals

• Renewable resources

How do fossil fuel power stations generate electricity?

• By using solar panels

• By burning fuels to create steam that drives turbines

• By using nuclear reactions

• By harnessing wind energy

Which of the following is a major disadvantage of using fossil fuels?

• They are the cheapest energy source

• They are abundant and easy to extract

• They produce no greenhouse gases

• They are non-renewable and contribute to global warming

What is a significant challenge in extracting fossil fuels?

• They are renewable and can be replaced quickly

• They are buried deep underground, making extraction costly

• They are found on the surface of the earth

• They are located in easily accessible areas

How long does it take for the amount of fossil fuels we use in one year to form naturally?

• 1,000,000 years

• 1,000 years

• 100 years

• 10 years
