The process is the sedimentation and lithification of ancient plant remains through compaction and removal of water via overburden pressure.
Start with a lush tropical swamp. Vegetation grows and dies, falling in the water but not decomposing. Millions of years of this occurs. Thickness of dead plant material grows and grows. Then, over millions of more years, this organic sediment is covered by a sea that comes and goes, depending on plate movement and crustal uplifting and rifting, depositing vast amounts of sand, mud, and clays over them. The pressure of the sediments above squeeze the water out of the organic sediment below, and in time these organic sediments become lithified (turned into rock).

Which element forms both coal and diamonds?
Carbon is the element that forms both coal and diamonds. The difference in their structure and properties is due to the conditions under which they are formed - coal forms under low pressure and temperature, while diamonds form under high pressure and temperature.
What element is found in coal or diamonds?
Coal and diamonds are both forms of carbon.
How does anthracite coal forms?
Anthracite coal forms from the metamorphism of bituminous coal under high pressure and temperature over millions of years. This process drives off volatile components and increases the carbon content, resulting in a coal with a high carbon and energy content.
What are the four forms of coal?
The four forms of coal are lignite, sub-bituminous, bituminous, and anthracite. These forms differ in their carbon content and energy value, with lignite being the lowest in carbon content and anthracite being the highest.
Is in unburned lump of coal Kendrick energy or potential?
In an unburned lump of coal, the energy is in potential form. When coal is burned, its chemical energy is converted into heat and other forms of energy.
What are coal and oil forms of?
Hydrocarbons
What are the forms of coal called?
Smog
Which element forms both coal and diamonds?

What are both lignite and anthracite forms of?

Why can't coal form in the arctic?
Coal forms mostly in tropical or temperate regions because it requires abundant plant growth and slow burial to undergo the necessary transformation into coal. The Arctic region has a colder climate and limited plant growth, making it unsuitable for coal formation.
Why is coal used for electricity?
When coal burns, it produces heat. This can be converted to other forms of energy.
What element is found in coal or diamonds?
Coal and diamonds are both forms of carbon.
What forms coal oils and gas?
acid rain
