What is the primary source of water in Niagara Cave?

The primary source of water in Niagara Cave is rainwater infiltration. This process occurs when rain falls on the surface, seeps into the ground, and gradually moves through soil and rock layers until it reaches the cave system. Rainwater is naturally acidic due to carbon dioxide absorption from the atmosphere and soil, which helps in the dissolution of limestone and contributes to the cave's formation over time.

While glacial runoff and lakes above the cave may contribute to the water dynamics in the area, they are not the primary source for the cave. Groundwater tables do supply water to subterranean systems, but in the case of Niagara Cave, it is the infiltration of rainwater that plays the most significant role in maintaining the flow and conditions within the cave environment. Understanding this process is crucial for recognizing how caves are formed and sustained.
