There are several forms of coal.
Going from softest to hardest.
Peat, Lignite, Coal, and Anthracite.
'Peat' is just like a soft dirty black earth,but it is coal in geoloicial formation.
Lignite is a soft black rock that can easily be broken.
Coal ; is a hard shiny black rock, that needs an axe or pick to break it.
Anthacite ' is a very hard shiny black coal, and does not break easily to an axe/pick.
They are all carboniferous and will burn with increasing degree of heat and decreasing emission of smoke.
What else can I help you with?
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.
Coal and diamond are two different forms of carbon which is more dense?
Diamond is more dense than coal. This is because diamond has a more tightly packed crystal structure, making it denser compared to coal which is less compact.
Is coal a black diamond?
No, coal and diamonds are two distinct substances. Coal is a fossil fuel formed from prehistoric plants, while diamonds are crystalline forms of carbon. Both may be used for various purposes, but they have different compositions and properties.
What element is found in coal or diamonds?
Coal and diamonds are both forms of carbon.
Can crude oil be found in coal?
No, crude oil is typically found in porous rock formations while coal forms from the compression of plant material over millions of years. The two resources have different origins and compositions, so crude oil is not found within coal deposits.
Cane you find gems in coal mines?
That would be pretty rare. The process that forms gemstones, and the process that forms coal are two entirely different matters. Where you find one, you would be unlikely to find the other.

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.

Is carbon a gas or solid?
it is ofcourse a solid. diamond and coal are two forms of carbon made compounds.
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.
