Which of the following does not influence rock weathering?
Answer Details
The answer is "ammonification". Ammonification is a biological process that converts organic nitrogen to ammonia and ammonium ions, which can contribute to soil fertility. However, it is not directly involved in rock weathering. The other options - water, carbonation, roots, and temperature - all play significant roles in the weathering of rocks. Water can cause physical weathering through erosion and can chemically weather rocks through dissolution and oxidation. Carbonation is the reaction of carbon dioxide with minerals in rocks, which can dissolve and break down the rock. Roots can grow into cracks in rocks and exert pressure, causing physical weathering. Temperature can also cause physical weathering through thermal expansion and contraction.
