Carboniferous and Permian
Hydrocarbons and coal were formed in what is known as the carboniferous era.
Yes coal was formed by the bio materials of forests and swamps and the energy as now came from the sun.
Most of our limestone formed during the Paleozoic era, approximately 500 to 250 million years ago. Coal formation occurred mainly during the Carboniferous period within the Paleozoic era, around 360 to 300 million years ago.
Layers of sediments compressed the layers of vegetation to form the coal deposits.
Coal is very old, it is believed to have been formed from plant matter that became buried in the Carboniferous Era, many millions of years ago.
Coal beds formed during the Carboniferous Period, approximately 300 to 360 million years ago. This period was characterized by extensive forests being buried and compressed over time, eventually transforming into coal deposits.
Most of our limestone and coal formed during the Carboniferous period, which lasted from about 359 to 299 million years ago. This era was characterized by lush, swampy environments that supported dense forests and abundant plant life, leading to the accumulation of organic material that eventually transformed into coal. Additionally, limestone formation was facilitated by the marine environments of the time, where calcium-rich organisms thrived.
Coal is formed from the remains of plants that lived and died millions of years ago. Over time, the plant material was buried and subjected to high temperatures and pressures, eventually transforming into coal.
coal. coal is formed.
Diamonds are not formed in coal: each is an allotrope of carbon and are formed by Mother Nature under entirely different circumstances.
Coal is formed from plants, which turned into peat, then lignite, then coal.
Dinosaurs did not appear until 40 million year after the end of the Carboniferous era when almost all of our coal resources were created. I find nothing of any significant economic value that formed in the era of the dinosaurs.
