Question

most fossil fuels derive their energy from which of these prehistoric processes? decomposition erosion fractures vulcanism

Explanation:

Fossil fuels (like coal, oil, natural gas) form from the remains of prehistoric plants and animals. Over millions of years, these organic materials undergo decomposition (along with heat and pressure) to form fossil fuels. Erosion is about wearing away of land, fractures are breaks in rocks, and vulcanism relates to volcanic activity—none of these directly create fossil fuels. So the correct process is decomposition.

Answer:

A. decomposition
