Natural gas is found in the lower rock layers because it is formed from the decomposition of organic matter over millions of years.

This process occurs deep underground, in the lower rock layers, where the conditions are suitable for the formation of natural gas. As a result, natural gas is typically found in reservoirs located in the lower rock layers of the Earth's crust. **
