Biological weathering is only weathering produced by creatures such as mammals, plants, fungi, and microorganisms such as bacteria. While some types of biological weathering, such as limestone breaking by tree roots, are classified as either physical or chemical, biological weathering can be either physical or chemical. We are biological beings.
einsteineruploaded with. Physical weathering is produced by mechanical pressures and has no effect on the rock's composition. Water, for example, can freeze inside tiny cavities in granite, causing it to split and fissure. Chemical weathering is produced by chemical processes in the rock and outs...
If you've ever seen a cracked pavement caused by a tree, you've undoubtedly witnessed biological weathering in action.Tree, grass, and other plant roots can develop into tiny areas and openings in rock. When these roots develop, they put weight on the surrounding rock, causing the spaces to enlarge or even fracture. Plant roots can withstand stones as well...
Weathering can also be caused by animals. Animals can stroll on or disrupt granite, resulting in falls that scrape or flatten the rock surface. Badgers and moles, for example, can break up limestone beneath or transport it to the surface, where it is subjected to other weathering factors. Some creatures burrow straight into the granite. The carapace of the piddock...
