Question

Explain formation of coal & petroleum :-)

Answer 1

Vegetation is the feed-stock for biogenic gas and Coal. Bionic meaning a methane gas that is young and formed by decaying vegetation. This gas is usually found in shallow wells and is natural in aquifers. Oil is formed by the deposition of small sea creatures such as plankton, krill etc. and covered by other sediments. After hundreds of thousands of years under pressure and heat it becomes oil. After much more heat, deeper depth and higher pressure that oil becomes thermogenic methane or natural gas that is found in deeper wells and in commercial quantities.

Answer 2

Petroleum (also known as crude oil or simply oil) is a fossil fuel that was formed from the remains of ancient marine organisms. Millions of years ago, algae and plants lived in shallow seas. After dying and sinking to the seafloor, the organic material mixed with other sediments and was buried... and The environments or conditions under which these coals were formed: anthracite coal, bituminous coal, lignite? Coal formed millions of years ago when the earth was covered with huge swampy forests where plants - giant ferns, reeds and mosses - grew. As the plants grew, some died and fell into the swamp waters.
