Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons coal is classified as a nonrenewable energy source because it takes millions of years to form coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Plant materials buried under sediments decay to form peat, a compressed mass of.
Coal – how it is formed coal is made from peat that has been compressed and then subjected to high temperature ( + 100° celcius) for a few million years to drive off moisture, methane and carbon dioxide bearing molecules. Accumulated, compacted and altered plants form a sedimentary rock called coal it is not only a resource of great economic importance, but a rock of intense fascination to the student of earth history although coal forms less than one percent of the sedimentary rock record, it is of foremost importance to the bible-believing geologist. It formed after lignite was exposed to more heat and more pressure bituminous is medium-hard coal, and had even more heat and pressure around it anthracite, the hardest coal, is a glossy black color.
