- Solution caves are formed in limestone and similar rocks by the action of water - After a rain, water seeps into cracks and pores of soil and rock - The water percolates beneath the land surface - Some of the water reaches a zone where all the cracks and pores in the rock are already filled with water - Rainwater absorbs some carbon dioxide as it passes through the atmosphere and even more as it drains through soil and decaying vegetation - The water combines chemically with the carbon dioxide - A weak carbonic acid solution is formed What might be the last step of the process?
----
Answer: This acid slowly dissolves calcite, forms solution cavities, and excavates passageways
