Which outcome sharply increases weathering rates where fractured limestone underlies shallow soil?

💡 Explanation

Karst topography formation accelerates due to weathering and dissolution by rain and groundwater accessing fractures via chemical weathering; this dissolution process enlarges fractures because the carbonic acid reacts with the calcium carbonate, therefore increasing weathering rates rather than other effects.
