Cave formation by groundwater is most common in which rock?
Answer and explanation
Correct answer: Limestone
Groundwater most readily forms caves in limestone because slightly acidic water reacts with and dissolves calcium carbonate along joints, bedding planes, and other openings. Continued solution enlarges these passages into caverns and other karst features. Therefore option B is correct. Granite, basalt, and quartzite are generally much less soluble under ordinary groundwater conditions, although cracks may still occur in them.
