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.
The limestone is more easily weathered than quartzite, leading to the formation of thicker soil above it. Limestone is more prone to chemical weathering, which breaks it down and creates a thicker layer of soil over time compared to the more resistant quartzite.
The soft greyish limestone that crumbles easily is called chalk.
Rainwater is naturally slightly acidic. The acid in rainwater reacts chemically with the calcium carbonate of limestone, dissolving it. The result is chemically weathered limestone, karst terrains, and cave structures.
I had the exact same question for one of my exams... I am fairly sure that the answer is: Granite and Limestone are two rocks that can be chemically weathered by natural rainwater. Hope I helped ! Alexx
Limestone is a rock that is easily dissolved by water, forming cavities and underground features like caves, sinkholes, and underground rivers. Over time, the natural processes of erosion and chemical weathering create these unique geological formations in limestone terrain.

Limestone and marble are two types of rocks that can be easily weathered by carbonic acid. This is because carbonic acid reacts with the calcium carbonate in these rocks, leading to the formation of calcium bicarbonate and ultimately causing dissolution and erosion of the rock.
Bedrocks such as limestone, dolomite, and gypsum are easily dissolved by running water due to their solubility in water. These rocks contain minerals that are easily weathered and dissolved, resulting in the formation of features like caves, sinkholes, and underground rivers.
Limestone and marble are two types of rock that are easily weathered by carbonic acid, which is a common acid found in rainwater. Over time, carbonic acid dissolves these rocks, leading to the formation of caves, sinkholes, and other karst topography features.
Sedimentary rocks are generally more easily weathered compared to igneous or metamorphic rocks. This is because sedimentary rocks are formed from sediments that are more loosely packed and may contain mineral grains that are less resistant to weathering processes.
