From the beginning of time, occurring over millions of years....
** Millions of years ago, the NE US to middle states was temperate and swampy. Water from the inland sea was still receding from the middle of the country. So, Pennsylvania, West Virginia, Ohio, Kentucky, Illinois, and Indiana had an abundance of coal made over many hundreds of millions of years, back in the era when glaciers were retreating and dinosaurs roamed.
The five steps of coal formation are: Peat formation: Plant material accumulates in wet environments. Lignite formation: Compression and heat turn peat into lignite, a soft coal. Sub-bituminous coal formation: Further compression and heat transform lignite into sub-bituminous coal. Bituminous coal formation: Continued heat and pressure convert sub-bituminous coal into bituminous coal, a higher quality coal. Anthracite coal formation: The highest level of metamorphism forms anthracite coal, a very high-quality and hard coal.
The first step of coal formation is the accumulation of plant material in a swampy environment. As plants die and accumulate, their organic matter is slowly buried under layers of sediment. Over time, this organic material undergoes chemical and physical changes, eventually transforming into coal.

It means the material added to a land form or land mass which is made of twigs, leaves, branches, and other plants that was broken up that is still remaining...Was that a simple definition for you? Here's the real hard words definition:The first stage in coal formation is the deposition of material composed of twigs, leaves, branches, and other plant debris.I hope my answer helped you!

The carbon content of coal-forming organic material increases with each step in coal formation. As the material is subjected to increasing pressure and temperature over time, it goes through various stages of coalification, leading to higher carbon content in the final product.

The materials formed at each step of the process are 1) Peat 2) Lignite 3) Sub-Bituminous and Bituminous Coal 4) Anthracite (may also form from oil) The final stage, which most coal does not reach, is graphite or pure carbon.

The ovarian cycle happens in 6 steps. STEP 1: Formation of the primary follicles STEP 2: Formation of Secondary Follicles STEP 3: Formation of a Tertiary Follicle STEP 4: Ovulation STEP 5:Formation and Degeneration of the Corpus Luteum STEP 6:Degeneration of the Corpus Luteum beginning Roughly 12 days after ovulation (unless fertilization occurs.)
What are the steps in the water cycle and what happens at each step
The first step in coal formation is the accumulation of organic material, such as plant debris, in a swampy environment. Over time, the organic material gets buried under layers of sediment, which leads to pressure and heat transforming it into peat.
In most cases the policy cycle consists of agenda setting, policy formation, policy implementation and policy evaluation. Agenda setting identifies issues. Policy formation analyzes and chooses policy options. Policy formation develops the strategy and policy evaluation monitors the results and compares them to the anticipated results.
