Which landform results within limestone when undersaturated runoff reaches bedrock?

💡 Explanation

Extensive cave systems develop because limestone undergoes dissolution via carbonic acid weathering underground; therefore, significant void spaces form over time, rather than surface features because the bedrock is directly attacked.
