Identifying rhyolite is like figuring out what kind of cookie you’re eating by looking at its shape and texture.
Rhyolite is a type of rock, and it’s made from molten rock that cooled down slowly underground. When it cools, it forms tiny crystals, which give the rock a smooth or bumpy look.
What Does Rhyolite Look Like?
Think about a crumbly granola bar, that’s kind of what rhyolite feels like. It can be light in color, almost like chalk, or have pretty colors inside, like a rainbow granola bar with different flavors mixed in. Sometimes it has white spots, these are quartz crystals, which are like little sugar grains in the rock.
How Do You Know It’s Rhyolite?
You can tell it's rhyolite by how it feels and looks. If it’s smooth or crumbly, and has tiny crystals inside, then you're probably holding rhyolite, just like you know a granola bar is your favorite snack when you see its colors and feel its texture!
Examples
