The Latin word fossilis means 'unearthed' or'excavated' because we need to excavate these fuels. In other words, they are buried deep inside the Earth and we need to dig them out.
Fossil fuels are made of plants and animals that died milIions of years ago and were converted-by the processes inside the
Earth--into coal, crude oil, or natural gas. The energy stored in these fossils can be released and used by burning them.
Searching for coal or crude oil, pumping outthese fuels from the depths, and transporting them require a lot of effort and time.The crude oil mustthen be convertedinto petrol for cars.
