Question

Differentiate between biological and anthropogenic weathering

Answer 1

Answer:

Biological weathering :

Biological weathering is the weakening and subsequent disintegration of rock by plants, animals and microbes. Growing plant roots can exert stress or pressure on rock. Although the process is physical, the pressure is exerted by a biological process (i.e., growing roots).

Anthropogenic weathering :

Anthropogenic disturbance of natural vegetation can profoundly alter the physical, chemical and biological processes within soils. ... However, the feedback mechanisms between soil erosion, chemical weathering and biogeochemical cycling in response to anthropogenic forcing are not yet fully understood.
