GENERAL GEOLOGY

Detailed explanation-1: -Coal is formed from ferns, plants and trees which hardened due to pressure and heat. Oil is formed from smaller organisms, like zooplankton and algae. Intense amounts of pressure caused this complex organic matter to decompose into oil.

Detailed explanation-2: -Plant matter It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in low-lying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.

Detailed explanation-3: -Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States. Fossil fuels are formed from the remains of ancient organisms. Because coal takes millions of years to develop and there is a limited amount of it, it is a nonrenewable resource.

Detailed explanation-4: -Coal is formed from buried remains of plant and animal matter.

Detailed explanation-5: -Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy-and carbon-dense black or brownish-black sedimentary rock.
