Coal is a combustible sedimentary rock formed from ancient vegetation which has been consolidated between other rock strata and transformed by the combined effects of microbial action, pressure and heat over a considerable time period. When burnt, coal releases energy as heat which has a variety of uses. …
What is a geologic resource?
• Geologic resources are valuable materials of. geologic origin that can be extracted from the Earth. – Many geologic resources originate in the hydrosphere. • Petroleum and coal come from organisms that lived and. died in water.
How is coal formed geologically?
In this video, a geologist describes how coal, a sedimentary rock, was formed when organic materials piled up in swamps millions of years ago. Over time, heat and pressure transformed the buried materials into peat and into various forms of coal. The geologist shows samples of low- and high-sulfur coal.
What is coal and how is it formed?
Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

What are the 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite.
Is Coal still being formed?
The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.
What rock is coal found in?
Does coal turn to diamond?
Over the years it has been said that diamonds formed from the metamorphism of coal. According to Geology.com, we now know this is untrue. “Coal has rarely played a role in the formation of diamonds. In fact, most diamonds that have been dated are much older than Earth’s first land plants – the source material of coal!
Where is coal naturally found?
Coal is mainly found in three regions: the Appalachian coal region, the Interior coal region, and the Western coal region (includes the Powder River Basin). The two largest coal mines in the United States are the North Antelope Rochelle and Black Thunder mines in Wyoming.
What are the advantages of coal?
Advantages of using coal to produce electricity:
