  • How does weathering affect limestone? - Internet Geography

    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. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.

  • Limestone Features - Geo for CXC

    Limestone is a sedimentary rock which is formed underwater. Some limestone consists mainly of coral or the shells of other small marine creatures. Limestone may also be precipitated from seawater. Limestone is a permeable rock. This means that water can enter limestone through pores, joints or cracks in the rock.

  • What is Chemical Weathering? - WorldAtlas

    Aug 23, 2017 · Carbonation of rocks containing calcium carbonate (limestone) is a common process of chemical weathering which leads to the formation of calcium bicarbonate that is highly soluble in water. Such reactions lead to the formation of hollow spaces in limestone that ultimately form limestone caves.

  • Weathering - Wikipedia

    Physical weathering. Physical weathering, also called mechanical weathering or disaggregation, is the class of processes that causes the disintegration of rocks without chemical change.The primary process in physical weathering is abrasion (the process by which clasts and other particles are reduced in size). However, chemical and physical weathering often go hand in hand.

  • Rates of Weathering | edHelper

    Limestone has the compound calcite. It is the carbonization of calcite that causes the increased rate of weathering of limestone. The material found in sediment grains also affects the rate of weathering. The mechanical weathering of rocks like shale and sandstone causes their grains to break up over time and become sand and clay particles. Why?
