Coal is Black and shiny, and will sheer easily. It is a mixture of many different organic compounds. Found/mined in specific minefields in the UK.
Flint is white/colourless and does not sheer easily(very hard). It is only one compound. sand (silicon dioxide) or possibly other crystalline solids held in the flint chemical lattice. It is found mainly in the clay vales of Southern England.

How do you tell the difference between Obsidian rock and Coal Flint rock?
Obsidian is a natural volcanic glass that is typically black and glassy in appearance, whereas coal is a sedimentary rock that is typically black and dull in appearance. Flint is a hard, sedimentary rock that often has a dark grey or black color with a smooth or waxy texture, whereas coal is formed from plant matter and is combustible.
How do you tell the difference between black jet and coal?
Jet is a type of lignite coal that is very hard and deep black in color, often used for making jewelry. Coal, on the other hand, is a sedimentary rock that is combustible and commonly used as a fuel source. The main difference between the two is their composition and uses.
What is the difference between brown and black coal besides their colour?
One main difference between brown coal (lignite) and black coal (anthracite) is their carbon content. Black coal has a higher carbon content and lower moisture content, making it a more efficient fuel source. Brown coal has a lower carbon content and higher moisture content, making it less energy-dense and less efficient.
What are two differences between peat lignite bituminous coal and anthracite coal?
One difference is their carbon content: peat and lignite have lower carbon content compared to bituminous and anthracite coal. Another difference is their formation process: peat is not fully coal yet, as it is the earliest stage of coal formation, while anthracite coal is the highest grade and the result of further coalification processes.
What is the difference between thermal coal and steam coal?
Thermal coal is a broad classification that includes various types of coal used for generating electricity or heat. Steam coal, on the other hand, is a specific type of thermal coal with high heat-producing properties, making it suitable for powering steam turbines in electricity generation. In essence, steam coal is a subtype of thermal coal used specifically for generating steam to produce electricity.
