Which mechanism accelerates formation of karst topography where limestone underlays boreal forests?

💡 Explanation

Organic acids from decaying matter in boreal forests enhance limestone dissolution via chelation, a form of chemical weathering. Higher acidity increases erosion rates, therefore more karst features develop, rather than from physical frost action alone, or other weathering forms.
