Types of Rocks

Limestone Limestone is a sedimentary rock. It is formed by layers of small pieces of rock and stones pressed hard together. The stone forms in wet areas which mean it will also contain of shells and waste matter from organisms that live in water.Limestone caves are formed when rainwater seeps through cracks in limestone rock and dissolves it.
