Which environmental condition can accelerate the erosion of limestone?

Frequent rainfall is the correct answer because it contributes significantly to the erosion of limestone through a process called chemical weathering. When rainwater combines with carbon dioxide in the atmosphere, it forms a weak carbonic acid. This acidic solution can seep into the porous limestone, slowly dissolving the calcium carbonate that makes up the rock. Over time, repeated cycles of rainfall amplify this process, leading to the breakdown and erosion of limestone formations.

While high temperatures may influence evaporation rates and potentially reduce water availability, they do not actively contribute to the erosion of limestone like rainfall does. Similarly, snow accumulation can lead to physical weathering when it melts, but it does not promote the chemical reactions necessary for limestone erosion. Strong winds can cause physical erosion by carrying abrasive particles, but they are not as effective in chemically altering limestone as frequent rainfall is.
