| In physical weathering, also known as mechanical weathering or disintegration, physical stresses combine to break rock apart. |
|
| Regions typically receive sufficient moisture to enable the physical weathering processes of salt crystal growth and hydration of salts. |
|
| Mass movements of soils and bedrock erosion in the headwater parts of stream watersheds represent the initial stages of material transport that is made possible by physical weathering. |
|
| Cryosols also are influenced by physical weathering, geochemical and biochemical weathering that occur at varying degrees. |
|
| Laterites develop from the intense chemical and partly also physical weathering of primary rocks in humid and warm climatic zones. |
|
| Due to the cold climate and dominance of physical weathering conditions, coarse or massive debris prevails. |
|
| These models usually consider physical weathering and treat the soil as a single layer of regolith. |
|
| On the surface of the Earth, water is important in both chemical and physical weathering processes. |
|
| Nurdles are also created through the physical weathering of larger plastic debris. |

|
| In non-ornithogenic soils, the presence of easily weatherable minerals in the clay fraction indicates that physical weathering occurs with limited chemical alteration of primary minerals. |
|
| Freeze-thaw conditions have the potential to increase frost action both in the formation of ice lenses and the physical weathering of the aggregate particle. |
