Southwest Monsoon Rainfall Statements Analysis
This solution analyzes two statements regarding the southwest monsoon rainfall patterns in India.
Statement A Evaluation: Monsoon Duration
Statement A claims: "The duration of southwest monsoon rainfall increases from south to north over India."
- The southwest monsoon typically arrives first over the southern parts of India (e.g., Kerala) in early June.
- It gradually progresses northwards.
- The monsoon retreats from northern India earlier (around September) compared to the southern parts.
- Therefore, the duration of active monsoon rainfall generally decreases from south to north.
- Conclusion: Statement A is incorrect.
Statement B Evaluation: Rainfall Amount in Northern Plains
Statement B claims: "The amount of rainfall in the southwest monsoon season in the northern plains of India decreases from east to west."
- The Bay of Bengal branch of the southwest monsoon brings significant rainfall to the northern plains.
- As this branch moves inland from east to west across the plains, it gradually loses moisture.
- Consequently, the rainfall amount tends to be higher in the eastern parts (like Assam, Bihar) and decreases towards the western parts (like Punjab, Rajasthan).
- Conclusion: Statement B is correct.
Final Answer Determination
Based on the analysis:
- Statement A is incorrect.
- Statement B is correct.
This corresponds to Option D.
