Why is limestone so easily weathered?

Answer 1

Some sedimentary rock, like limestone, is susceptible to chemical attack from acidic rainfall due to its carbonate chemistry. Other sedimentary rock, like shale, is prone to freeze/thaw cycles due to the easily penetrated fractured layering. Sedimentary rocks like sandstone can be poorly cemented or porous, allowing for attack and disintegration by freezing or moving water, or dissolution of the cementing minerals.
