Answer
Coalification

The correct answer is Coalification — The overall process of these transformations is called coalification.

Step-by-step solution

  1. Plant debris accumulates in swampy conditions forming peat.
  2. Peat gets buried under sediments, increasing temperature and pressure.
  3. Heat and pressure drive chemical changes and loss of water, converting peat into lignite, then sub-bituminous, bituminous, and finally anthracite.
  4. The overall process of these transformations is called coalification.
Common mistake: identifying only the peat stage
