Slate is a fine-grained, foliated metamorphic rock formed from shale under heat and pressure. Known for its durability and smooth, layered texture, slate is commonly used in roofing, flooring, countertops, and blackboards. It splits easily into thin sheets and comes in various natural colors such as gray, black, green, and purple. Slate is both functional and aesthetically valued in architecture and design.
