The coal deposits we use today formed in what type environment during the Paleozoic?

The coal deposits we use today primarily formed in lush, swampy environments during the Carboniferous period of the Paleozoic era. These settings were characterized by dense vegetation, including ferns and giant trees, which accumulated in waterlogged areas. Over millions of years, the organic material from this vegetation was buried and subjected to heat and pressure, transforming it into coal.
