Consider the following pairs: Types of Chemical Weathering Characteristics I. Solution Results in leaching of minerals II. Carbonation Helps in breaking down feldspars III. Hydration Causes an increase in the volume of rocks IV. Oxidation Changes the colour of rocks How many pairs given above are correctly matched?

Options

  1. AOne
  2. BTwo
  3. CThree
  4. DAll the four

Correct answer

D. All the four

Step-by-step solution

Chemical weathering processes include solution, carbonation, hydration, and oxidation. I. Solution involves the dissolution of soluble minerals in water or weak acids, leading to the leaching of minerals from rocks. This pair is correctly matched. II. Carbonation is the reaction of carbonates and bicarbonates with minerals. It is a common process that helps in the breaking down of feldspars and carbonate minerals. This pair is correctly matched. III. Hydration is the chemical addition of water. Minerals absorb wate
