Question

select the correct answer. which energy source is formed when organic matter is trapped underground without exposure to air or moisture? a. natural gas b. coal c. oil d. biomass fuels

Explanation:

Coal is formed from the remains of plants that were buried and subjected to high - pressure and heat over millions of years in an oxygen - poor environment (trapped underground without exposure to air or moisture). Natural gas is also formed from organic matter but through different processes and under different conditions. Oil is formed from the remains of marine organisms. Biomass fuels are derived from recently living organisms and not from long - term burial of organic matter in an air - and moisture - free environment like coal.

Answer:

B. coal
