Chemical erosion is a process where rocks and minerals break down due to chemical reactions. This often occurs when water, acids, or other chemicals interact with the minerals in the rocks, leading to changes in their composition. For example, carbonic acid formed from carbon dioxide in rainwater can dissolve limestone, causing it to erode over time. This type of erosion can significantly shape landscapes, creating features like caves and sinkholes. It plays a crucial role in the rock cycle, contributing to soil formation and nutrient release, which are essential for ecosystems. Understanding chemical erosion helps in managing natural resources and protecting the environment.
