What is the major force that changes peat to coal?

The primary force that transforms peat into coal is heat, which comes from geological processes over millions of years. As layers of sediment accumulate, the pressure rises, compacting the peat and driving off moisture. The increasing temperature from the Earth's interior also contributes to chemical changes, converting the organic material into the carbon-rich substance we recognize as coal. In addition to heat and pressure, time plays a crucial role in this transformation. It takes millions of years for peat to metamorphose into various types of coal, influenced by factors such as the type of vegetation, the deposition environment, and the amount of geological activity. So, patience is key in this ancient, fascinating process!
