1C: Energy Generation and Fossil Fuels

Which of the following is an advantage of fossil fuels?

• They are renewable and sustainable.

• They have a high energy density.

• They produce no greenhouse gases.

• They are abundant and easy to extract.

Which of the following is a disadvantage of fossil fuels?

• They are renewable sources of energy.

• They contribute to environmental pollution.

• They are abundant and easily accessible.

• They have no impact on climate change.

What is the difference between sustainable and Environmental?

• Sustainable refers to practices that do not deplete resources, while environmental pertains to the natural world.

• Sustainable and environmental mean the same thing.

• Sustainable is about economic growth, while environmental is about social issues.

• Sustainable is a type of environmental issue.

A carbon footprint is:

• The total amount of greenhouse gases produced by human activities, usually expressed in equivalent tons of carbon dioxide (CO2).

• A type of carbon-based shoe print.

• A measure of the carbon content in the soil.

• The amount of carbon in a diamond.

Fossil fuels come from

• ancient organic matter

• modern synthetic processes

• mineral deposits

• volcanic activity

Explain how power is generated from coal, gas, and oil.

• Power is generated by burning these fuels to produce steam that drives turbines.

• Power is generated by using solar panels to convert sunlight into electricity.

• Power is generated by harnessing wind energy to turn turbines.

• Power is generated by using nuclear reactions to produce heat.

The environmental impact of power generation from fossil fuels is primarily due to:

• Greenhouse gas emissions

• Water pollution

• Deforestation

• Noise pollution

Explain the arguments for and against the selection of fossil fuels.

• Fossil fuels are abundant and provide a stable energy source, but they contribute to environmental pollution and climate change.

• Fossil fuels are renewable and environmentally friendly, but they are expensive and difficult to extract.

• Fossil fuels are the only source of energy available, and they do not have any negative impacts.

• Fossil fuels are cheap and easy to extract, but they are not a stable energy source.

What percentage of power comes from natural gas power stations?

• 22%

• 30%

• Less than 1%
