What natural process contributes to the formation of caves like Niagara Cave?

• A. Glacial movement
• B. Wave erosion
• C. Acidic water dissolving limestone
• D. Mineral sedimentation

Answer: (C)

The formation of caves such as Niagara Cave is primarily influenced by the natural process of acidic water dissolving limestone. This process, known as chemical weathering, occurs when rainwater absorbs carbon dioxide from the atmosphere and soil, creating a weak acid called carbonic acid. When this acidic water seeps into the ground and contact with limestone, it can react with the calcium carbonate in the limestone, leading to the gradual dissolution of the rock. Over long periods, this action erodes the limestone, enlarging fractures and cavities, which eventually can develop into extensive cave systems. The unique geological features of Niagara Cave, with its stunning stalactites and stalagmites, are direct results of this ongoing dissolution process. This forms the basis for spectacular underground landscapes. Other options do not play a significant role in cave formation at Niagara Cave. Glacial movement typically shapes the surface geology of an area rather than forming caves directly. Wave erosion is associated with coastal processes and does not apply to limestone caves located inland. Mineral sedimentation refers to the deposition of minerals from water, which is more related to geological formations like sedimentary rock layers, not specifically cave development.
