Which common, rock-forming mineral or mineral group is most readily dissolved by groundwater?

Question

Quizplus · Accepted Answer

Calcite is a mineral that is readily dissolved by groundwater, especially if the water is slightly acidic. This is because calcite is a primary component of limestone and is also a common mineral in many sedimentary rocks. As the water flows through these rocks, it dissolves the calcite, leading to the formation of groundwater caves, sinkholes, and other features. Quartz, feldspars, and clay minerals, on the other hand, are more resistant to dissolution by groundwater due to their chemical and physical properties.
