Decay plant-peat-bituminius coal -anthracite is it correct series?

No, the correct series of decay for plant material to form coal is plant-peat-lignite-bituminous coal-anthracite. Peat is the precursor to coal and undergoes further stages of heat and pressure to form lignite, bituminous coal, and finally anthracite.

Yes, the series is correct. It represents the stages of coalification, which is the process of coal formation from plant material.

- Decay is the initial stage, where plant material is broken down by bacteria and fungi.
- Peat is formed when the decayed plant material accumulates in waterlogged conditions, preventing further decomposition.
- Bituminous coal is formed when peat is subjected to heat and pressure, causing the loss of moisture and volatile components.
- Anthracite is the final stage of coalification, where bituminous coal is subjected to even greater heat and pressure, resulting in a high carbon content and low volatile content.
