Biological Weathering by Microorganisms

  Biological weathering only refers to weathering caused by plants, animals, fungi, and microorganisms such as bacteria. It is contributed to or removal of ions and minerals from the weathering environment and physical variations due to movement or development of organisms. It is also the wearying and subsequent fragmentation of rock by plants, animals, and microbes. Agents of Biological Weathering In the next section, we talk about the agents of biological weathering such as microorganisms, humans, plants and animals. Biological Weathering by Microorganisms Wedging and burrowing by organisms like termites, earthworms, rodents, etc. help in showing the new surfaces to chemical attack and helps in the penetration of air and moisture. Bacteria, mosses, algae, and lichens frequently grow on rock surfaces, particularly in humid areas. They form weak acids, which can convert some of the minerals to clay. Algae growth can deteriorate several rock types and make it more exposed to weather...
