1. Plant Material Accumulation: The process of coal formation starts with the accumulation of plant material in a swampy area. This plant material includes trees, ferns, and other plants that have the ability to live in low oxygen conditions.

2. Peat Formation: Over time, the plant material gets covered by water and dirt, preventing it from decaying completely. This leads to the formation of peat, which is a brown, soil-like material.

3. Formation of Lignite: As more and more layers pile up on top of the peat, it starts to compress due to the weight. This compression, along with the heat of the earth, transforms the peat into lignite, which is a brownish-black coal with high moisture content.

4. Formation of Bituminous and Anthracite Coal: Further compression and heat leads to the formation of bituminous coal, which is a black coal that has a high energy content. If the process continues, the bituminous coal can turn into anthracite, which is the highest grade of coal and has the highest carbon content.

5. Mining: Once the coal has been formed, it can be mined and used for various purposes, such as electricity generation or steel production.
