Which of the following statements are correct?I. Non-renewable resourc...
Explanation:

Non-renewable resources:
- Non-renewable resources are those which once used up cannot be replaced within a reasonable period of time. Examples include fossil fuels like coal, oil, and natural gas.

Coal and natural gas:
- Coal and natural gas are not inexhaustible resources. They are finite resources that are formed over millions of years and can be depleted with continuous extraction.

CNG vs. petrol:
- Contrary to the statement, Compressed Natural Gas (CNG) is actually less polluting than petrol. CNG produces lower levels of harmful emissions such as carbon monoxide, particulate matter, and nitrogen oxides compared to petrol.

Conversion of buried vegetation into coal:
- The high temperature and high pressure inside the earth slowly converts the buried vegetation into coal over millions of years. This process is known as coal formation.
