Read the following statements with reference to soil
(i) Weathering is a very fast process of soil formation
(ii) Percolation of water is faster in sandy soils
(iii) Loamy soil contains only sand and clay
(iv) Top soil contains the maximum amount of humus.
Choose the correct statements from the above

Options

A. (ii) and (iv)
B. (i) and (iii)
C. (ii) and (iii)
D. (i) and (ii)

Explanation

To determine the correct statements regarding soil from the given options, we can analyze each statement step by step.

### Step 1: Analyze Statement (i)
**Statement:** Weathering is a very fast process of soil formation.
**Analysis:** Weathering refers to the breakdown of rocks and minerals into smaller particles, which is a slow process. It involves physical, chemical, and biological factors that take time to alter the materials.
**Conclusion:** This statement is **incorrect**.

### Step 2: Analyze Statement (ii)
**Statement:** Percolation of water is faster in sandy soils.
**Analysis:** Percolation is the process of water moving downward through soil. Sandy soils have larger particles and more space between them, allowing water to flow through more quickly compared to other soil types.
**Conclusion:** This statement is **correct**.

### Step 3: Analyze Statement (iii)
**Statement:** Loamy soil contains only sand and clay.
**Analysis:** Loamy soil is a mixture of sand, clay, and silt, along with organic matter. It is known for its fertility and good drainage properties. Therefore, saying it contains only sand and clay is misleading.
**Conclusion:** This statement is **incorrect**.

### Step 4: Analyze Statement (iv)
**Statement:** Top soil contains the maximum amount of humus.
**Analysis:** Topsoil, typically referred to as the A horizon, does contain organic matter but is not the layer with the maximum humus. The O horizon, which is the uppermost layer, contains the most humus.
**Conclusion:** This statement is **incorrect**.

### Final Conclusion
Based on the analysis:
- Statement (i) is incorrect.
- Statement (ii) is correct.
- Statement (iii) is incorrect.
- Statement (iv) is incorrect.

Thus, the correct statements are only **(ii)**.
