Rainwater mixed with carbon dioxide forms a mild acid similar to that present in soda. As the acidic water percolates below ground, it dissolves carbonate limestone rocks. When this process occurs for thousands of years, large spaces can open up, forming caves. As water continues to drip down through a cave, it redeposits some minerals, producing formations such as stalactites and stalagmites.
