Soil has particles of different sizes. Arrange the words given below in increasing order of their particle size. Rock, Clay, Sand, Gravel, Silt

Options

A. Gravel < Slit < Sand < clay < Rock
B. Clay < Sand < Silt < Gravel < Rock
C. Clay < Slit < Sand < Gravel < Rock
D. Rock < clay < Sand < Gravel < silt

Answer

To arrange the given words in increasing order of their particle size, we need to understand the size of each type of soil particle. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Identify the smallest particle**:
- The smallest soil particle is **Clay**. Its size is less than 0.002 mm.

2. **Next size up**:
- The next larger particle is **Silt**. The size of silt particles ranges from 0.002 mm to 0.05 mm.

3. **Following that**:
- After silt, we have **Sand**. Sand particles are larger than silt, with sizes ranging from 0.05 mm to 2 mm.

4. **Larger particles**:
- The next in size is **Gravel**. Gravel particles range from 2 mm to 64 mm.

5. **Largest particle**:
- Finally, the largest particle is **Rock**. Rock particles can range from 4.75 mm to 75 mm.

### Final Arrangement:
Putting it all together in increasing order of particle size, we have:
- Clay
- Silt
- Sand
- Gravel
- Rock
