What metamorphic rock does anthracite coal turn in to?
Anthracite coal, a type of coal with a high carbon content and low impurities, can turn into metamorphic rock called graphite under high heat and pressure. Graphite is a soft, crystalline form of carbon that is a good conductor of electricity.
Which type of coal contains highest percentage of carbon?
Anthracite coal has the highest percentage of carbon among the different types of coal.
Which coal type is harder anthracite or bituminous?
Anthracite is harder than bituminous coal. Anthracite has a higher carbon content and lower moisture content, making it a more dense and harder coal type.
What is the hardest and oldest type coal?
Anthracite is the hardest type of coal.
What metamorphism does coal produce?
Coal undergoes low-grade metamorphism, transforming into a type of metamorphic rock known as anthracite. This process involves the heating and pressurizing of coal over millions of years, resulting in a higher carbon content and a more compact, harder texture compared to the original coal.
Is anthracite coal a sedimentary rock?
No. Anthracite coal is a metamorphic rock.
Is Anthracite coal igneous metamorphic or sedimentary?
Anthracite coal is a type of metamorphic rock. It forms from the transformation of bituminous coal under increased temperature and pressure over time.
What type of coal is a sedimentary rock?
All types of coal are sedimentary, except anthracite which is metamorphic.
What metamorphic rock does anthracite coal turn in to?
Anthracite coal, a type of coal with a high carbon content and low impurities, can turn into metamorphic rock called graphite under high heat and pressure. Graphite is a soft, crystalline form of carbon that is a good conductor of electricity.
What is a very hard rock that burns with a high heat and smoke a metamorphic rock formed from coal?
The rock you are referring to is anthracite coal, which is a type of metamorphic rock formed from coal with a high carbon content. Anthracite coal burns with a high heat and produces little smoke due to its high carbon content and low volatile matter.
What can anthracite be classified as?
Anthracite is a type of coal.
What is anthracite a type of?

Is anthracite an igneous metamorphic or sedimentary?
Anthracite is a metamorphic rock. Anthracite is formed when an organic sedimentary rock - coal - is compressed and heated in the ground.
