Which weathering outcome results when carbonic acid reacts with limestone?

💡 Explanation

Karst topography forms via dissolution when carbonic acid (from rainfall) reacts with calcium carbonate in limestone; chemical weathering, specifically dissolution, creates caves and sinkholes because the limestone is progressively dissolved rather than undergoing physical breakdown or compositional changes, resulting in the drainage and landforms related to karst.
