What are the three erosional features caused by groundwater in carbonate rocks?

Groundwater erosion in carbonate rocks primarily results in the formation of caves, sinkholes, and karst landscapes. Caves develop as acidic groundwater dissolves the limestone, creating extensive underground systems. Sinkholes occur when the ground surface collapses into voids created by the dissolution of the rock. Karst landscapes are characterized by features such as ridges, depressions, and steep-sided hills, shaped by the combined effects of erosion and dissolution over time.
