Unformatted text preview: Solution: The solution of soluble minerals e.g. limestone in rocks. 5. Hydrolisis: The reaction between the hydrogen ions in water and some metal ions. 2. Mechanical Weathering: 1. Temperature changes causing expansion and contraction of rocks. 2. Freezing of water--frost action. 3. Wetting and Drying Factors Influencing the Character and Rate of Weathering These factors include: Climate o The greater the amount of rainfall the higher the rate of chemical weathering. o Temperature changes accelerate the rate of mechanical weathering. The nature of the parent rock. Vegetation cover The gradient of the slope Time Man's activities...
