Slate is a special kind of rock that forms from clay and volcanic ash. π
It's usually gray, blue, green, or even purple! Did you know that slate is found all over the world? Major countries like the United Kingdom, Spain, and the United States have huge amounts of it. Slate is strong, smooth, and can be split into thin layers. This makes it useful for many things we use every day, like roofs and chalkboards! π
So, next time you're in school and enjoying your chalkboard, think of the amazing slate that made it possible!
