We just learned about the rock Petoskey.
We've learned about how rocks are mostly made up of other types of rocks that have either been squished together, melted together or piled on top of each other.
The building blocks of rocks are called minerals.
Some types of minerals are like crystals, and some are more like metals.
When these minerals get crushed, melted or squished together, they can make up rocks.
Like the rock marble that we learned about before is made up of the minerals calcite and dolomite.
