Limestone is weathered by mechanical and chemical means:
Mechanical: plant root growth in cracks and crevices, frost wedging, rock falls, abrasion.
Chemical: exposure to fluids containing acids--particularly rainwater and flowing runoff that is naturally acidic--that chemically react with the calcium carbonate in the limestone, dissolving it.

What happens when it rains on limestone?
When rain falls on limestone, a chemical reaction occurs causing the limestone to dissolve. This process is called carbonation and results in the formation of calcium bicarbonate, which can be washed away over time by the rainwater. As a result, limestone can be weathered and eroded by rainfall.
Which kinds of rock can easily be weathered by carbonic acid?
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.
What type of rocks are more easily weathered?
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.
What types of bedrock are dissolved most easily by running water?
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.
To which Limestone called siliceous Limestone?
The siliceous limestone that is commonly found is known as chert or flint. It is a type of limestone that has a high silica content, giving it a distinctive appearance and often used for various purposes such as construction, decoration, and tool-making.

What are two types of rock that easily get wetherd by acid?
Limestone and chalk get easily weathered by acid.
What happens when it rains on limestone?

Sediment is made from pieces of?
Sediment is made from clay, gravel, some organic matter, weathered limestone and basalt.
