how does biological weathering occur
Dear student, Biological weathering is weathering caused by plants and animals. biological weathering is of two types: by physical means or by chemicals and organic compounds. Biological weathering by physical means occurs when a force or pressure is applied to break rocks apart or degrade the minerals in them. By increasing the exposed surface area of rocks, they make it possible for other physical factors to speed up their degradation. For example tree root, Burrowing animals like shrews, moles, earthworms, and even ants contribute to biological weathering. Biological weathering by chemical means are type of weathering, when living organisms contribute through their organic compounds that contain molecules that acidify and corrode rock minerals. Because of such mechanism, biological weathering is also referred to as organic weathering. With regards!
