El desgaste y la erosión: desgaste químico

The video explains chemical wear, focusing on how air, water, and other substances react with rocks and metals. Water is highlighted as a common agent, dissolving minerals and forming acids that accelerate rock decomposition. Oxidation, another form of wear, is described through rust formation on metals. Biological factors like lichen and plant roots also contribute to chemical wear by releasing acids. The video emphasizes the combined effects of chemical and mechanical wear on soil materials.
