From what I know, limestone is alkali, and high pH water would not weather alkali things. For the case of limestone, it might even make the limestone bigger (think so).
The type of climate that a limestone will weather more quickly i think will be a hot and dry climate.
A limestone monument would weather most quickly in a warm and humid climate, as high temperatures and moisture can accelerate the process of erosion and dissolution of limestone. Additionally, exposure to acid rain can further speed up the deterioration of limestone monuments in such climates.
sprinkle water on it
Limestone weathers the fastest in areas with high levels of rainfall and acidic conditions, as these factors can accelerate the breakdown of the calcium carbonate in limestone. Additionally, warm temperatures and biological activity can also contribute to faster weathering of limestone.
Limestone roofs in Bermuda naturally disinfect rainwater as it passes through the porous material. The high pH level of the limestone helps kill bacteria and impurities in the rainwater, making it safe for collection and use. Additionally, the limestone filters out debris and contaminants as the water seeps through.
The Rock Composition really affects the rate of weathering because different types of rocks will react differently to water and other substances. If you pour water on flat marble and leave it, the water would usually leave a mark or a stain on marble depending on what color the marble is. If the marble is black, the stain would have a high chance of being gray. If you pour water on a slab of limestone, the water would have a high chance of just passing through. After a few times of pouring, the slab of limestone would have like an indent if all of the ours were in the same place.
both limestone and sandstone are highly permeable to water. As there are often toxic substances which leak from landfill, it is necessary to collect water which falls on the heap. For this reason, permeable rocks like limestone and sandstone are not the ideal basement for a landfill, and may require significant infrastructure to prevent contamination of the water table below the landfill. They are ideal landfills if the need is there for drainage. Permeable rock has many uses in landfill. Landfill in areas that are naturally high in limestone or sandstone content would have no issues with a little more of either material in it.
Chemical weathering of limestone would occur most rapidly in a warm and wet climate, where there is abundant rainfall and high temperatures to facilitate the dissolution and erosion of the limestone.
clodudy
The limestone turns into marble because of the tremendous pressures and high temperatures.
Limestone weathers most rapidly when exposed to acid rain due to its high calcium carbonate content which reacts with acidic water to form soluble calcium bicarbonate, leading to its dissolution.
How is the weather today? In a sentence: "The weather was terrible today."
