Why does the solution capacity of karst water increase?
Answer and explanation
Correct answer: Dissolved carbon dioxide forms weak carbonic acid in water
Rainwater absorbs carbon dioxide from the atmosphere and especially from soil, forming weak carbonic acid. This slightly acidic water reacts with calcium carbonate in limestone and converts part of it into soluble bicarbonate. Repeated passage through joints enlarges cracks, caves, and other karst features. Wind speed and falling tides do not control this chemical solution process.
