How do ferns turn into coal?

Answer 1

Ferns, along with other plant material, contribute to coal formation through a process called coalification. After ferns die, they accumulate in swampy environments, where they are buried by sediment. Over millions of years, heat and pressure transform this organic material into peat, and eventually into coal through a series of chemical and physical changes. This process can take millions of years, resulting in the carbon-rich deposits we mine today.
