A common type of rock used for writing is slate, which is a fine-grained metamorphic rock that can be easily split into thin sheets. Historically, slate was used for blackboards and writing slates due to its smooth surface and durability. Another hard surface suitable for writing is granite, often used in monuments and gravestones, where inscriptions can be carved deeply. Both materials provide a lasting medium for written expression.
Such rock is extrusive igneous rock.
This is described as a normal fault.
