A seam
A person who gets coal from under the ground is typically called a coal miner.
Coal is removed from deep underground through a process called underground mining. This involves digging shafts into the ground, then using machinery to extract the coal from the coal seam. Miners then transport the coal to the surface for processing and distribution.
Coal beds are layers of hardened plant material that have been compressed over millions of years underground. These beds are rich in carbon and are one of the main sources of coal used for energy production. Coal beds are often found in sedimentary rock formations.
its i dont know because this crossword sucks
Coal that is still in the ground is referred to as coal seam or coal deposit.
A person who gets coal from under the ground is typically called a coal miner.
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.
small pieces of coal are called slack. Thank you!
Coal is removed from deep underground through a process called underground mining. This involves digging shafts into the ground, then using machinery to extract the coal from the coal seam. Miners then transport the coal to the surface for processing and distribution.
Under pressure, coal can undergo a process called coalification, where layers of compacted plant material are transformed into different types of coal such as lignite, bituminous, and anthracite. This process occurs over millions of years as a result of geological forces.
When swamp plants are buried under pressure for a long time, they may eventually transform into coal through a process called coalification. This process involves the decomposition of plant matter under high pressure and temperature, resulting in the formation of coal deposits.
Yes, coal is often called "black diamond" due to its appearance and value as a source of energy. The comparison is made to highlight the significance of coal as a valuable resource similar to how diamonds are valued for their rarity and beauty.

Coal is black under standard conditions.
Coal beds are layers of hardened plant material that have been compressed over millions of years underground. These beds are rich in carbon and are one of the main sources of coal used for energy production. Coal beds are often found in sedimentary rock formations.
A coal mine is typically referred to as a coal mine.
Excavated coal is commonly referred to as "mined coal."
