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.
What is harder lignite or anthracite coal?
Anthracite coal is harder than lignite coal. Anthracite has a higher carbon content and is more dense and brittle compared to lignite, which is softer and more crumbly.

What are the 4 stages of coal formation?
The four stages of coal formation are peat, lignite, bituminous, and anthracite. Peat is the first stage and is partially decomposed plant material. As the peat is buried and compressed, it transforms into lignite, then bituminous coal, and finally anthracite, which is the most carbon-rich and hardest form of coal.
