Groundwater plays a critical role in the formation and development of caves over extensive periods. As water seeps through soil and rock, it becomes slightly acidic due to the carbon dioxide it picks up from decaying organic matter. This acidity allows the groundwater to dissolve limestone or other soluble rocks, leading to the gradual carving out of passages, tunnels, and chambers within the cave system. This ongoing process is known as chemical weathering or dissolution, and it is fundamental in shaping the unique geological features that can be observed in caves, including stalactites and stalagmites. Therefore, the processes driven by groundwater are pivotal in creating and maintaining the captivating formations found in caves like Niagara Cave.

While flooding can occur during heavy rainfall, this does not contribute to the long-term shaping of the cave's features. The introduction of minerals can enhance the beauty of cave formations but is not the primary means by which the cave features are formed. Cooling effects from groundwater are minimal and do not significantly influence the development of cave features. Thus, the correct answer highlights the essential role of groundwater in continually shaping the cave's structure over time.
