1.	1. Why are coal and petroleum called fossil fuels?
Answer» <p>Petroleum, natural gas, and coal are the main sources of energy for modern use. All of these fuels are classified asfossil fuels. The reason they are called fossil fuels is because they are all made from decayed plants and animals that have been preserved in the earth 's crust by pressure, bacterial processes and heat. It takes millions of years for these organisms to chemically change into fossil fuels. we need to conserve them because these are non-renewable resources means these can not be re-produced.</p>
