Biological weathering finally, there is biological weathering, which is weathering caused by a living organismremember, weathering does not remove the material in question, so humans mining and quarrying materials is not an example of biological weathering. Biological weathering is caused by activities of living organisms - for example, the growth of roots or the burrowing of animals tree roots are probably the most occuring, bu t can often be by animals.
Freeze thaw/frost shattering: when water gets into cracks in rocks during the day and during the night it freezes (total volume expansion of 9%) and this widens the rock, eventually causing the rock to shatter salt crystallisation: this is when saline water enters the pores of the rocks and then. Animals and plants can wear away rocks this is called biological weathering for example, burrowing animals such as rabbits can burrow into a crack in a rock, making it bigger and splitting the rock.
