It may be nearly impossible to tell because of the overlap of vegetation.
Coal is the remains of ancient plant matter compressed by millions of tons of stone and dirt layers. So coal has energy that it got from those original plants. The plants got their energy from the Sun, mostly. So, it is acceptable to say that coal obtains its energy from the Sun.
The layers of coal are called peat, lignite, subbituminous, bituminous caol, and anthracite. Peat being the most inexpensive and anthracite being the most valuable. Most coal in use is bituminous. Another answer: A layer of coal in a mine is called a coal seam.
By digging big holes (called coal mines) in the ground and separating the coal, rock, and soil in the material dug from those holes. Coal usually comes in layers (called seams) between layers of other sedimentary rocks.
charcoal is a half burned wood where as stone like coal is a mineral found naturally.
what coal is is layers of ancient dead plants so for every layer of dead plants is another layer of coal that is formed

Yes, they are called coal seams.
Layers of sediments compressed the layers of vegetation to form the coal deposits.

It is sand. Edit: Over many thousands of years - sediment gets compressed and compacted into layers. The layers form rocks such as slate and coal.

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

when coal is mined from earths surface,people remove the layers of soil above the coal
