Match the following lists :
| List-I (Soil and vegetation) | List-II (Infiltration rate (mm/hr) |
|---|---|
| P.Forested loam | 1.10 – 70 |
| Q.Loam pasture | 2.0 – 4 |
| R.Sand | 3.3 – 15 |
| S.Bare clay | 4.100 – 200 |
Select the correct answer using the code given below :
- A2 3 1 4
- B3 1 2 4
- C4 1 3 2Correct
- D4 1 2 3
Solution
Concept
Infiltration rates of soils
Step-by-step solution
1. Forested loam has very high infiltration: 100–200 → 4. 2. Loam pasture: 10–70 → 1. 3. Bare clay has almost no infiltration: 0–4 → 2. 4. Sand (as tabulated, with cover) → 3 (3–15) by elimination.
Explanation
Vegetation and loose soil structure raise infiltration, while bare clay seals over.
Why the other options are wrong
The other codes give bare clay a high rate or forested loam a low rate.
Shortcut
Forest highest, bare clay lowest.
Correct answer: C) 4 1 3 2
