Read the given statement and select the correct option. Statement-1: Soil serves as a reservoir of essential elements.
Statement-2: Soil develops, over the years, through physical and chemical weathering of rocks.

Options

A. both statements 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect
C. Statement 1 is incorrect but statement 2 in correct.
D. Both statements 1 and 2 are incorrect.

Explanation

To solve the question regarding the two statements about soil and its properties, we can follow these steps:

### Step-by-Step Solution:

1. **Analyze Statement 1**:
- The first statement claims that "Soil serves as a reservoir of essential elements."
- **Explanation**: Soil is indeed the topmost layer of the Earth's surface and is crucial for sustaining terrestrial plant life. It contains a variety of essential elements and nutrients that plants need to grow. On average, soil contains around 60 essential elements that are vital for plant health.

2. **Conclusion for Statement 1**:
- Since soil does serve as a reservoir of essential elements, Statement 1 is **correct**.

3. **Analyze Statement 2**:
- The second statement asserts that "Soil develops, over the years, through physical and chemical weathering of rocks."
- **Explanation**: Weathering refers to the process of breaking down rocks into smaller particles, which eventually leads to the formation of soil. This process can be physical (like temperature changes), chemical (like reactions with water), or biological (like the action of microorganisms). Therefore, the development of soil through weathering is a well-established fact.

4. **Conclusion for Statement 2**:
- Since soil does develop through the weathering of rocks, Statement 2 is also **correct**.

5. **Final Conclusion**:
- Both statements are correct. Therefore, the correct option is that both Statement 1 and Statement 2 are correct.
