sandstone and shale
from my grandad(a miner deputy manager) mainly trees very rare for animals, always lowerlifeforms
Coal is formed by the compression of dead plant material over millions of years. This organic material undergoes chemical and physical changes due to pressure and heat, transforming it into coal.
Bituminous coal is most like the organic matter from which it formed as it is formed from the slow accumulation and compression of plant materials over time. It retains a higher carbon content compared to other coal types and has a relatively high energy content.
Obsidian and coal are both types of rocks formed through natural processes. However, obsidian is an igneous rock formed from volcanic activity, while coal is a sedimentary rock formed from the compression of plant material over millions of years. Both rocks have been valuable resources to human civilizations throughout history.
Coal is formed from the remains of plants that lived millions of years ago and went through a process of decomposition and compression. Oil, on the other hand, is formed from the remains of marine plants and animals that were buried and subjected to high pressure and heat over time.
Anthracite coal is a type of metamorphic rock that is formed from the compression of plant material over millions of years. It has a high carbon content and a lustrous appearance, making it a valuable source of energy.

Rocks formed from ancient plants are called coal. Coal is a sedimentary rock that forms from the accumulation and compression of plant material over millions of years.

Chalk and coal are examples of biochemical sedimentary rocks. Biochemical sedimentary rocks are formed from the accumulation and compression of organic remains such as shells, coral, or plant material.

Peat is an early stage of coal formation and has the lowest carbon content, followed by brown coal (lignite) with a higher carbon content. Black coal (bituminous coal) has the highest carbon content among the three and is formed from further compression and heating of brown coal over time. Black coal is the most energy-rich and commonly used type of coal for electricity generation.

Coal is a sedimentary rock because it forms from the accumulation and compression of plant remains (organic matter) in swamps and peat bogs over millions of years. These plant materials undergo chemical and physical changes as they are buried and compressed, eventually forming coal.
Coal was formed when massive amounts of vegetation died and fell into the swamps they grew in. This happened in the Carboniferous Period. Huge mats of waterlogged plant material were formed that resisted decay because there was very little oxygen there. Over millions of years, as the climatic and geologic conditions changed, these plant sediments were covered and compacted by other sediments, resulting in their conversion to coal.
