Shale is a sedimentary rock that, when subjected to heat and pressure, transforms into a metamorphic rock called slate. This process, known as metamorphism, alters the mineral composition and texture of the original rock.
Slate is characterized by its fine-grained texture and is often split into thin layers or sheets, making it an ideal material for various applications, including roofing and flooring. The metamorphic process not only changes the physical structure but can enhance the durability and aesthetic appeal of the rock.
In summary, the metamorphic rock formed from shale is slate, and its formation is a remarkable example of how geological processes reshape materials over time.
