Lignite coal
Definition
Lignite coal is a type of low-grade coal that is brownish-black in color. It is formed from peat through the process of coalification and has a lower carbon content compared to other types of coal.
Analogy
Think of lignite coal as the "baby" of the coal family. Just like how babies are not fully developed yet, lignite coal is not as mature or energy-dense as other types of coal.
