UPSC CAPF – 2021
– Carbonation: Reaction of carbonic acid (formed from CO2 dissolved in water) with minerals, especially carbonates.
– Solution: Minerals dissolving directly into water.
– Hydrolysis: Reaction between water molecules and rock-forming minerals, leading to decomposition.
– Oxidation: Reaction of minerals with oxygen, often involving iron-bearing minerals (rusting).
Types of physical weathering include freeze-thaw (frost wedging), exfoliation, thermal expansion/contraction, abrasion, biological activity (root wedging), and salt crystal growth.
