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.
Is anthracite coal a sedimentary rock?
No. Anthracite coal is a metamorphic rock.
Is anthracite a nonrenewable source of energy?
Yes, all forms of coal (anthracite is just the most clean burning form) are fossil fuels and thus nonrenewable.
What type of coal probably formed from the greatest pressure?
Anthracite coal likely formed from the greatest pressure, as it is the highest grade of coal and has undergone the most intense metamorphism.
What is the original form of anthracite coal?
Anthracite forms from the metamorphism of bituminous coal. The metamorphism occurs due to pressures and temperatures from depth of burial or stresses derived from plate movements.
Which list presents in correct order forms of coal from the first stage?
