Which geomorphic outcome occurs when slightly acidic groundwater interacts chemically with limestone?

💡 Explanation

Karst topography forms because the dissolution of calcium carbonate in limestone by carbonic acid creates channels and sinkholes initiating landform development; therefore Karst emerges, rather than lake formation which arises from river meandering.
