'Peat' is coal in the natural making.
However, the next stage of formation is 'lignite';
The youngest and softest coal is lignite. It is also known as brown coal and is formed from peat under moderate pressure and heat, making it less carbon-dense and softer compared to other types of coal like bituminous or anthracite.

The youngest and softest type of coal is lignite. It has a low carbon content and a high moisture content, making it less dense and softer compared to other types of coal.
