प्रश्न
Fossil fuels are ______, ______ and ______.
उत्तर
Fossil fuels are coal, petroleum, and natural gas.
Explanation:
These were formed from the dead remains of living organisms (fossils), so they are all known as fossil fuels. It requires millions of years to convert dead organisms into these fuels, but these known reserves will last only a few hundred years. Burning these fuels is a significant cause of air pollution, and their use is also linked to global warming. Therefore, it is necessary that we use these fuels only when necessary.
