Coal forms when dead plant material builds up and up to form peat, which is the first step. This is compacted between layers of sedimentary rock, forming a rock called lignite. Then this is compacted even more. Then, heat and pressure deep deep beneath the surface create anthracite, or coal. Coal is a metamorphic rock.

What is a form of soft and brownish coloured coal?
Lignite is a form of soft, brownish-colored coal that is often referred to as brown coal. It is one of the lower-ranked types of coal in terms of carbon content and energy output.
Is lignite a form of coal?
Yes. Lignite is also known as brown coal. It is not exactly the same as coal (bituminous or anthracite) but it is near the beginning of the process that makes coal. Lignite has about 1/3 to 1/2 the carbon content of coal.
How is a anthracite coal formed?
Anthracite coal is formed by the further metamorphism of bituminous coal. This process involves high pressures and temperatures, which leads to the coal becoming harder and more carbon-rich. Anthracite coal is the highest rank of coal and has a high carbon content and low impurities.
