How Is Limestone Eroded

Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. … Rainwater erodes the vertical joints and horizontal bedding planes in limestone (see image below). In doing this karst scenery is created.

How does limestone deteriorate?

Limestone subjected to exterior exposures deteriorates due to weathering or the natural effects of wind, rain, and thermal change. Limestone is extremely durable.

What happens to limestone over time?
