What Is Coal and How Does It Form?

What is of Coal? 
Coal is one of fossil fuels. Generally Understanding is a sedimentary rock that can be burned, formed from organic sediments, primarily the remains of plants and formed through a process updates. Elements Consist primarily of carbon, hydrogen and oxygen.

How is Coal formed? 
The form of the accumulated remains the coal plant, typically in the swamp. When the remains of dead plants and falling into the swamp was standing water marshes to protect them from decay. Swamp waters typically starved of oxygen, the which will react with the plant remains and causing rot. 

The composition of coal .

Based on the composition and the properties of the coal ranks was assigned to development in accordance with the level of the organic of metamorphosis. The development of bases ratings is summarized 

Lignite coal 
The lignite is the and lowest rank of the coal. This was peat that has turned into the stone and the stone is brown-black of coal. Lignite will sometimes recognizable Contain the plant structure. 

Coal sub Bituminous 
Sub-bituminous coal is the lignite roomates had increasing the level of the organic of metamorphosis. This metamorphosis had been motivated by a number of oxygen and the hydrogen in the coal. 

Bituminous coal 
The bituminous coal is the most abundant rank. It accounts for approximately 60% of the total of the coal produced in the USA. Was formed when bituminous sub-bituminous coal roomates had Increased the level of the organic of metamorphosis. 

Anthracite coal 
The anthracite is the highest rank of the coal. It has a carbon content of more than 87% of dry ash-free basis. Anthracite coal typically has highest calorific values ​​per tonne of the minerals materials for free.
