Which mechanism primarily shapes karst landscapes given rainfall thresholds?

💡 Explanation

Karst landscapes are predominately shaped by carbonic acid dissolution because rainwater mixes with carbon dioxide in the soil, forming carbonic acid (H₂CO₃), which then dissolves carbonate rocks like limestone. Without this dissolution, other geological processes would dominate, rather than karst topography formation.
