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.
There are two main types of physical weathering: 1  Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. 2  Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.
