what process hollows out limestone caves

2021-12-8 · What Process Hollows Out Limestone Caves? 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 TO CALCULATE EFFICIENCY OF YOUR LIME …2017-5-8 · limestone.
