Exercise 2: Read a passage about fossil fuels. Decide if the statements are true (T) or false (F). Circle T or F.
There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs – therefore we call them fossil fuels.
Fossil fuels take millions of years to make. But they are not unlimited. We are using up the fuels that were made more than 300 million years ago. They are not renewable solar power, wind power, hydro power or biomass. Once they are gone they are gone. So, it’s best not to waste fossil fuels.
We can save fossil fuels by conserving energy. One simple way to do this is to turn off appliances, TVs and radios that we are not using. We can also turn off lights when no one is in the room. Another way is to go by bike or walk instead of driving cars or motorbikes.
1. Three major forms of fossil fuels are oil, coal and natural gas. T
2. They were formed right after the time of dinosaurs. F
3. Once fossil fuels are gone, they will come back later F
Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no coal, oil and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind, and the water.
Solar energy is unlimited. The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperature of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source of power.
