How does weathering affect limestone? - Internet Geography

2021-4-12  Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve.

Weathering of Limestone

2012-8-31  Limestone is a chemical sedimentary rock that is created from the remains of calcium bearing organisms and chemical precipitants. The calcium can come from the shells and/or the skeletal fragments of deceased organisms. Over millions of years, the calcium normally contained within the shells of marine and land organisms is broken down and put into solution. Calcium rich solutions are left to settle while the water evaporates. Through deposition and heating from Earth, this calcium rich location will become a limestone deposit. Due to the nature of limestone to slowly dissolve when in the presence of a light acid as well as allow water to pass through the matrix of the limestone,

2020-4-16  Weathering is an essential process that affects the physical and mechanical properties of rock material and mass at shallow depths and on the surface through chemical and physical weathering. Physical weathering leads to the opening of discontinuities by rock fractures, progressively breaking down the original rock to a soil-like material representing advanced stages of weathering.
