Why can biological weathering be categorized as both physical and chemical weathering?
Plant roots physically wedge into andexpand cracks in rocks causing them to break further. Mechanicalbreakage of rocks also occurs when trees in rocky terrainare knocked over and uprooted, such as by strong winds. Acids from decaying organic matter contributeto chemical weathering by solution. Lichens growing on rockscan physically dislodge particles and they also secrete acidicsubstances that mix with water from precipitation encouragingchemical weathering by solution.
