give reason coal and petroleum are known as precious natural resources
Answers
Answer:
The fossil fuels we use today are actually formed from plants and animals that existed hundreds of millions of years ago. Coal and petroleum are made of dead matter buried under the earth for many years. The dead and decaying matter under great amount of pressure and temperatures turn into fossils and they both are used as fuels, called fossil fuels.
Answer:
Coal and petroleum are called non renewable resources because they cannot be formed quickly. They take a lot of time to form. They take even millions and billions of year to be formed.So coal cannot be replenished within a given time.
ALSO
Coal and petroleum are called fossil fuels. Coal and petroleum are the natural resources which are important 'sources' of energy for us. Coal is used as a fuel as such in homes and in industry, or it is used to generate electricity at Thermal Power Plants.
ALSO
Over millions of years, heat and pressure from Earth's crust decomposed these organisms into one of the three main kinds of fuel: oil (also called petroleum), natural gas, or coal. Materials, substances, and organisms found in nature that are useful to humans, like fossil fuels, are called natural resources.
