What is Limestone?

Limestone is made up of the shells of millennia old dead sea creatures.
Layers of these built up over millions of years, and were squashed together until they formed limestone.
This means it is a sedimentary rock.

Limestone (CaCO3) is formed from seashells by a process that takes millions of years.

Limestone is used to make many things in our everyday lives, such as glass, cement, paper and buildings.
