How limestone is eroded

Limestone is a sedimentary rock that is made up of horizontal blocks called bedding planes and vertical cracks called joints. Limestone is also a permeable rock which means that water can pass through its joints and cracks.

Limestone is made of calcium carbonate which is dissolved by rainfall, a weak carbonic acid. This process is called chemical weathering.
