Question

which of the following best describes peat?
a liquid form of fossil fuel
an unnatural flammable gas
a decayed inorganic material

Explanation:

Peat is an organic material formed from partially decayed plant matter in wet, anaerobic conditions. It is the first, earliest stage in the geological process that leads to the formation of coal over millions of years. It is not a liquid fossil fuel, not an unnatural gas, and it is organic (not inorganic) material.

Answer:

an early stage of coal formation
