above limestone formation is usually identified by the very low SPT-N values or low cone resistance where SPT-N values of zero are often detected. The formation is either due to subsurface erosion as a result of overburden slumping into cavities in the limestone or residual weathering of ancient karst features (Tan & Ch'ng 1986). FLOATER FLOATERCalcium carbonate can be used to reduce the amount of greenhouse gases in the atmosphere. It can be used to create a carbon sink, which is a method of storing carbon dioxide from the atmosphere in a natural, long-term storage system, such as limestone formations, allowing the greenhouse gases to be removed from the atmosphere.It is a pattern which has been formed by the movement of water through limestone, always seeking available openings and the easiest path downward to a lower level and finding some limestones more soluble than others. The long passageways of the cave follow the northwestward dip of the rocks toward the Western Coal Field.

Research Question: How does the varying pH level of rainwater influence the rate of limestone weathering in different geographical locations?. Hypothesis: If rainwater pH levels are lower (more acidic), then the rate of limestone weathering will be higher, particularly in geographical areas rich in limestone formations, due to increased chemical dissolution.

The development of most caves begins in the zone of saturation just below the water table. As groundwater infiltrates the cracks and joints of limestone formations, it gradually dissolves the adjacent rock and enlarges these passages to form an interconnected network of openings.
