  25. Fossil fuels:
    1. Some examples of fossil fuels are coal, oil and gas.

    2. Living things turn into fossil fuels when they die because they all contain carbon and carbon is one of the main ingredients to create fossil fuels.

    4. Three things that are needed to create fossil fuels are heat, time and pressure.

    5. The meaning of the statement, changing the recipe a little can change the fossil fuel you produce at the end, means that if you change either the heat temperature, time or pressure it will change the fossil fuel end result.

    6. Fossil fuels are a non renewable resource.

    7. The disadvantages of burning fossil fuels are that it causes climate change, the take millions of years to make and they are already running out.

    8. Seven of the most wealthiest nations have decided that they are going to get rid of fossil fuels due to all of the disadvantages.

    9. Some other energy options that could be used instead of fossil fuels are wind energy, solar energy and wave energy.

    10. We think it’s a good idea for them to get rid of fossil fuels because climate change is destroying our earth.

  26. 1. A wind turbine is taller than a 20 story building and each blades are bigger than a bus
