उत्तर
Thousands of years ago, fossil fuels were formed when vegetation was buried in the ground due to storms, floods, and earthquakes. It requires very high pressure and temperature to form. Such high pressure and temperature cannot be achieved in the laboratory. These resources are available in limited quantities. That is why fossil fuels are exhaustible natural resources.
