Ground water level is continuously decreasing which of the following can be reason for it?

Options

A. (a)Afforestation as more trees consume more water so ground water level Is decreasing
B. (b)Construction of large number of water bodies
C. (c)Large number of tube-wells and hand pumps are extracting water from ground
D. (d)Excessive rainfall

Answer

To solve the question regarding the decreasing groundwater level and identify the correct reason from the given options, we can follow these steps:

### Step 1: Understand the Question
The question asks for the reasons behind the continuous decrease in groundwater levels. We need to analyze each option provided to determine which one correctly explains this phenomenon.

### Step 2: Analyze Each Option
1. **Option A: Afforestation**
- Afforestation refers to the planting of new trees. While it is true that trees consume water, afforestation typically leads to increased rainfall and better water retention in the soil. Therefore, it usually contributes to an increase in groundwater levels rather than a decrease.
- **Conclusion**: This option is incorrect.

2. **Option B: Construction of Large Number of Water Bodies**
- The construction of water bodies, such as dams, is aimed at preserving water. These structures help in storing water and can actually contribute to the replenishment of groundwater levels.
- **Conclusion**: This option is also incorrect.

3. **Option C: Large Number of Tube Wells and Hand Pumps Extracting Water from Ground**
- This option indicates that the extraction of water through tube wells and hand pumps is excessive. Frequent pumping of groundwater without adequate replenishment leads to a decrease in groundwater levels. This is a well-known cause of declining groundwater levels.
- **Conclusion**: This option is correct.

4. **Option D: (Not provided in the transcript)**
- Since we do not have the details of option D, we cannot analyze it. However, based on the analysis of options A, B, and C, we can conclude that option D is likely incorrect if it does not relate to excessive water extraction.

### Step 3: Final Conclusion
After analyzing all the options, we find that the correct answer is **Option C: Large number of tube wells and hand pumps are extracting water from ground.** This is the primary reason for the continuous decrease in groundwater levels.
