why coal is considered has exhaustable resource
Answers
Answer:
hey
Explanation:
because coal is formed under the surface of earth. Fossil fuels require millions of years to form from the dead vegetation and animals that get buried deep inside the Earth. They require high temperature and pressure for their formation, which cannot be provided in the laboratory. Thus, fossils are limited. Therefore, the use of fossil fuels at this rate will lead to their exhaustion.

Hii ! Here is your answer : Coal is a complex mixture of carbon, hydrogen and oxygen compounds. me nitrogen, sulphur and phosphorus compounds are also present in it. It is found in coal mines deep under the surface of earth. Story of formation : It is believed that millions of years ago, the ground below the forests was split open by natural forces such as earthquakes and volcanoes. The forests got buried under the surface of earth. Thus, the plants had no contact with oxygen. Successive layers of sediments sealed the buried plants. Over millions of year, these deposits were subjected to tremendous pressure and heat finally transformed them into coal.the coal is called as exhaustible resource because coal is formed under the surface of earth... we are extracting coal from underground... if we use more the coal will be completed...so it is called as exahaustible resource.
Thank you
