Coal is deposited usually in layers, underground, sometimes fairly close to the surface.

Why black coal is considered to be a metamorphic rock?
Coal is generally considered a sedimentary rock as it is made up of deposited material (in this case organic matter, mostly from plants) and is eventually covered up by overburden. I'm not going to go into the details of the physical change but the reason black coal might be considered metamorphic is that it has been subjected to more pressure over time which furthers the coalification process. The order of coalification coal: peat -> lignite (brown coal) ->sub bituminous -> bituminous ->anthracite (very rare) everything after lignite is black in colour. If you need this for a report I'd probably look it up though, its been a while since I've studied coal in depth.
What is soil deposited by water called?
Soil deposited by water could be silt or mud.
What are rocks snd soil deposited by streams called?
they are deposited by sediment
Where is silt and soil deposited?
Silt and soil are most deposited in the water and then it goes in to the rivers or oceans :)
What is soil deposited by wind kwown as?
that would be know as loess: soil believed to be mainly deposited by wind
How is coal deposited?
how is coal depossited
Coal reserves that you harvest today were initially deposited during the?
Carboniferious period
How does coal gets between layers of shale?
First, a layer of clay that would turn to shale was deposited. Next, a layer of plant life that would become coal was deposited, then another layer of clay. Over time, the clay became shale, and the plants became coal. Sort of like how did the blanket on your bed get between the sheets and the bedspread? You put on the sheets, then the blanket, then the bedspread.
Where do coal oil and gas come from?
Plants and animals that lived in the ancient, geological past and have become buried in the Earth's rocks as they were deposited.
How is coal created and where does coal it come from?
coal is created by the deposition and compaction of huge plant(organic) material deposited into a basin,with the increasing depth the high rank of coal is formed. The order is:- peat>lignite>bituminous>anthracite Peat is formed at shallow depth and on moving downward anthracite is formed at greater depth.
What event caused the tree trunks of many trees in England to from light to dark?
Burning of coal during the industrial revolution and later deposited soot on the trees.
What is the angle of repose of coal?
Initially the seam would have been deposited tangentially to the circumference of the Earth (flat). Subsequent to this the angel would depend on tectonic movements that may have deformed the sediments containing the coal seam. The angle of repose could therefore be anywhere from vertical to horizontal.

What fuel was created from plant and animals decaying?
Fossil fuels (coal, oil and natural gas) are made from ancient plants and animals. Organic matter deposited 300 million years ago came under great pressure and over the years turned into coal, oil and gas.
What is formed when pressure sqeezes moisture out of peat?
Dried peat. Only after subsequent layers of sediments have been deposited on top, year after year, century after century, eon after eon, will the pressure lithify the peat into coal.
The earliest record of mammals comes from which of what rock layers?
The earliest record of mammals comes from sedimentary rock. Sedimentary rocks are deposited in layers. They are an important source of natural resources, such as coal, fossil fuel, and ore.
