How caves form | Caves and karst | Foundations of the Mendips

How caves form. Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

How Mammoth Cave Formed - National Park Service

Solution caves form when rainwater percolates through the soil, picks up carbon dioxide (from both the air and soil), forming a weak acid. This acidic water squeezes between the small cracks and layers of bedrock, such as limestone, and dissolves out a small channel in the rock for the water to flow. The water actively dissolves minerals in the ...
