Probably bituminous, the "middle grade" of coal. Lowest is lignite, which is usually only used in underdeveloped countries as it has low heat output and high pollution. Above bituminous is anthracite, an excellent, very hard (and very expensive) coal. When you ask most people to visualize a lump of coa in their mind, ninety to ninety-five percent of them will visualize bituminous.
Peat is sometimes considered a type of coal-so surely it must be seen as the most common. There is a lot of bituminous ("soft") coal. Anthracite ("hard") coal, which produces less air pollution, is less common.
Bituminous coal is the most common type of coal.
Carbon is the most common element found in coal and soot. It is a key component of these substances and is responsible for their dark color.
Black coal is a type of coal that is dark in color and is primarily composed of carbon. It is commonly used as a fuel source for generating electricity and in industrial processes due to its high energy content.
The three main types of coal are anthracite, bituminous, and lignite. Anthracite is the highest rank of coal, known for its high carbon content and low moisture content. Bituminous is the most common type of coal, with a balance of carbon and volatile matter. Lignite is the lowest rank of coal, with high moisture content and low carbon content.
Bituminous coal, or soft coal, is the most common type of coal produced in the United States.
# WHAT IS THE MOST COMMON FORM OF COAL IN Pennsylvania?

Coal is very common. Caves are a good source of coal, but if you are mining, coal is most common at y=48.

The most common rock in Pennsylvania is sedimentary rock, particularly shale and sandstone. These rocks are formed from sediment that has been compacted and cemented together over time. Other common rocks in Pennsylvania include limestone and coal.
The three most common fossil fuels are coal, oil, and natural gas. These resources are formed from the decomposition of organic matter over millions of years and are widely used for energy production worldwide.
