Answer Details
An example of a rock formed by wood subjected to pressure and heat is lignite.
Lignite is a type of coal that is formed from peat, which is partially decomposed plant material. Over time, peat can be buried and subjected to high pressure and temperature, causing it to undergo a process of coalification.
During this process, the plant material in the peat is gradually transformed into coal. Lignite is the lowest rank of coal, and is characterized by its brownish-black color and relatively low energy content.
Lignite is formed from the compression and heating of wood, which is a type of plant material. So, lignite is an example of a rock formed by wood subjected to pressure and heat.
