What Type of Rock Does Slate Change Into?
Slate is a metamorphic rock. Metamorphic rocks are rocks that change form from one type of rock into another because of time, pressure, heat and other factors. Diamonds are the most famous of metamorphic rocks, starting out as humble coal. Other metamorphic rocks include slate, shale, schist, gneiss and marble. The new form of a rock is determined by the composition of the original rock.
