Question

Match LIST I with LIST II
\[ \begin{array}{|l|l|} \hline \textbf{LIST I} & \textbf{LIST II} \\ \hline A. \ \text{Wind break} & I. \ \text{Surface creep movement} \\ B. \ \text{Boraxing soil particles} & II. \ \text{Suspension movement} \\ C. \ \text{Coarse soil particles} & III. \ \text{Saltation movement} \\ D. \ \text{Floating soil particles} & IV. \ \text{Vegetative barrier for wind erosion} \\ \hline \end{array} \]
Choose the correct answer from the options given below:

• A. A-II, B-IV, C-I, D-III
• B. A-IV, B-III, C-I, D-II
• C. A-IV, B-I, C-II, D-III
• D. A-IV, B-II, C-I, D-III

Hint:

Remember the three modes of wind transport: 1. Suspension: Very fine particles (dust) float long distances. 2. Saltation: Fine/medium sand particles bounce along the surface (accounts for most transport). 3. Surface Creep: Coarse sand/gravel particles roll or slide. \textbf{Windbreaks} are vegetative barriers to stop all three.

Answer 1

The Correct Option is D

Step 1: Analyze and match the terms based on standard wind erosion principles. The terminology in LIST I is non-standard, requiring interpretation.
- A. Wind break: This is a row of trees or shrubs planted to reduce wind speed and control wind erosion. It is a IV. Vegetative barrier for wind erosion. (A \(\rightarrow\) IV)
- C. Coarse soil particles: The largest particles moved by wind are rolled or pushed along the surface. This process is called I. Surface creep movement. (C \(\rightarrow\) I)
- B. Boraxing soil particles: "Boraxing" is not a standard term. It might be a severe typo. If it refers to very fine dust particles that are lifted high into the air, this would correspond to II. Suspension movement. (B \(\rightarrow\) II)
- D. Floating soil particles: This likely refers to particles that are lifted and bounce along the surface, which is the definition of III. Saltation movement. (D \(\rightarrow\) III)
Step 2: Compile the interpreted pairings.
The logical pairings based on this interpretation would be A-IV, B-II, C-I, D-III. This combination matches option (D). While the terms "Boraxing" and "Floating" are unusual, this matching provides the most physically coherent explanation for the wind erosion processes described.
