How Are Caves Formed? – startcaving

The water carries small rocks and sand. These are capable of eroding much harder rock than limestone. Erosional caves can be formed in even the hardest of rock, such as granite. There are also erosional caves formed by the wind. That's right, wind carrying particles of sand can whip around a cliff face, eventually carving a hole in the rock.Web

Limestone caves

The resulting cave formations have a waxy, glistening appearance. Loss of carbon dioxide through evaporation plays a much lesser role, usually in areas of high airflow near cave entrances, but the resulting cave formation usually look dull and chalky. Bacterial and algal colonies can also play a role in deposition of calcium carbonate.Web
