Consider the following:
1. Wild animals
2. Lichens and Mosses
Which among the above can cause Biological weathering?
All of the above can cause biological weathering. Lichens and mosses grow on essentially bare rock surfaces and create a more humid chemical microenvironment. The attachment of these organisms to the rock surface enhances physical as well as chemical breakdown of the surface microlayer of the rock.
