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: Standard wind erosion principles are applied to analyze and match terms. Terminology in LIST I requires interpretation as it is non-standard.
- A. Wind break: A row of trees or shrubs planted to reduce wind speed and control wind erosion. This aligns with IV. Vegetative barrier for wind erosion. (A \(\rightarrow\) IV)
- C. Coarse soil particles: The largest particles moved by wind, typically rolled or pushed along the surface. This process is known as I. Surface creep movement. (C \(\rightarrow\) I)
- B. Boraxing soil particles: "Boraxing" is an unconventional term, potentially a significant typographical error. If it denotes very fine dust particles lofted high into the atmosphere, it corresponds to II. Suspension movement. (B \(\rightarrow\) II)
- D. Floating soil particles: This term likely refers to particles lifted and bouncing along the surface, consistent with the definition of III. Saltation movement. (D \(\rightarrow\) III)
Step 2: Interpretations of pairings are compiled.
Based on this interpretation, the logical pairings are A-IV, B-II, C-I, and D-III. This combination corresponds to option (D). Despite the unusual phrasing of "Boraxing" and "Floating," this matching offers the most physically plausible explanation for the described wind erosion phenomena.
