Coal from the ship Titanic, SEM
Coloured scanning electron micrograph (SEM) of Coal from the ship Titanic. Coal is a fossil fuel (combustible sedimentary rock) that forms when dead plant matter is converted into peat. Over time geological processes convert peat into lignite, then sub-bituminous coal, then bituminous coal, and finally anthracite. Magnification: x535 when shortest axis printed at 25 millimetres.
