â¢ Weathering can be physical, organic, or chemical whereas erosion is plain movement of rock pieces from one place to another. â¢ It is because of both weathering and erosion that we get to see new geological features. We cannot stop weathering from happening.
Biological Weathering vs. Physical and Chemical Weathering. The three different types of weathering are physical, chemical and biological. Physical weathering is caused by mechanical forces, without any change to the makeup of the rock.icroorganisms and Lichens. Not all biological weathering occurs visibly. Many microorganisms in the soil and on the surface of rock can contribute.
