Percolation of soil water to water table occurs through

Options

A. Micropores less than `0.2mum`
B. Micropores between 0.2 to 20.0 `mum`
C. Macropores between 20-50`mum`.
D. Macropores bigger than 50 `mum`.

Answer

To solve the question regarding the percolation of soil water to the water table, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Percolation**:
- Percolation is the process by which water moves through the soil and filters down to the water table. It involves the movement of liquid through a porous medium.

2. **Identify the Role of Pores**:
- For percolation to occur, the soil must have pores that allow water to pass through. The size of these pores is crucial for determining how effectively water can percolate.

3. **Evaluate the Options**:
- **Option 1**: Microspores less than 0.2 micrometers - These are too small for effective percolation.
- **Option 2**: Microspores between 0.2 to 20 micrometers - These are also too small for effective percolation.
- **Option 3**: Macropores between 20 to 50 micrometers - While larger than the previous options, these are still not sufficient for optimal percolation.
- **Option 4**: Macropores bigger than 50 micrometers - This option indicates larger pores, which are suitable for percolation.

4. **Determine the Correct Answer**:
- Since percolation requires pores that are 50 micrometers or larger, the correct answer is **Option 4: Macropores bigger than 50 micrometers**.

### Final Answer:
The percolation of soil water to the water table occurs through **macropores bigger than 50 micrometers** (Option 4).
