Answer :

Final answer:

Fossil fuels are non-renewable due to their lengthy formation process over millions of years.

These fuels, including coal, oil, and natural gas, are formed from ancient organisms over extended periods of time, making their replenishment rate significantly slower than the rate at which they are consumed.
