  • What type of weathering is most common in limestone

    What Type Of Weathering Is Most Common In Limestone

    Dec 14, 2018 chemical weathering. 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.

  • How does weathering affect limestone

    How Does Weathering Affect Limestone

    Sep 26, 2019 Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock. Carbonic acid is especially effective at dissolving limestone.
