They are abundant and easy to access.

What is a significant consequence of using fossil fuels such as coal, gas, and oil?

• They improve air quality.

• They help in reducing global warming.

• They damage the earth's climate.

• They are renewable sources of energy.

Answer explanation

Using fossil fuels such as coal, gas, and oil leads to damaging the earth's climate due to the release of greenhouse gases.

Why is it important to find 'cleaner' sources of energy?

• Fossil fuels are unlimited.

• Fossil fuels are running out.

• Cleaner sources are more expensive.

• Cleaner sources are less efficient.

Answer explanation

It is important to find 'cleaner' sources of energy because fossil fuels are running out, making it necessary to transition to more sustainable options.

What do all fossil fuels produce when burnt?

• Oxygen and nitrogen

• Carbon dioxide (CO2) and water vapour

• Methane and hydrogen

• Sulfur dioxide and ammonia

Answer explanation

When burnt, all fossil fuels produce carbon dioxide (CO2) and water vapour.

Which of the following is one of the most damaging greenhouse gases?

• Methane (CH4)

• Nitrous oxide (N2O)

• Carbon dioxide (CO2)

• Ozone (O3)

Answer explanation

Carbon dioxide (CO2) is one of the most damaging greenhouse gases due to its long-lasting impact on the environment and contribution to global warming.

Which sources are mentioned as producers of CO2 in the text?

• Solar panels and wind turbines

• Power stations, boilers, and fires

• Hydroelectric dams and geothermal plants

• Nuclear reactors and tidal power stations

Answer explanation

The sources mentioned as producers of CO2 in the text are power stations, boilers, and fires.

Which of the following is considered a solid fuel?

• Fuel oil

• Natural gas

• Coal

• Electricity

Answer explanation

Coal is considered a solid fuel because it is a natural resource that can be burned to produce heat and energy.
