Q12. Which of the following represents the correct north to south sequence of the confluence of these tributaries with the Luni river?
Explanation
The Luni River receives various tributaries as it flows from the Aravallis towards the southwest. Arranged from north to south based on their confluence points, the sequence begins with the Guhiya, followed by the Bandi and then the Sukri. The Jawai River joins further south. This spatial arrangement reflects the drainage pattern of the western Aravalli slopes into the desert’s artery.
Q13. The Ghaggar river, a major seasonal river of northern Rajasthan, originates from which of the following regions?
Explanation
The Ghaggar River, an important seasonal stream in northern Rajasthan, originates in the Shivalik Hills of Himachal Pradesh. It flows through Punjab and Haryana before entering the Hanumangarh district. Often associated with the ancient Saraswati River, it is the main river of Rajasthan’s internal drainage system in the north, typically drying up in the sands near the international border.
Q14. Identify the incorrect statement regarding the Ghaggar river.
Explanation
The Ghaggar is a classic example of an internal drainage river and does not reach any ocean or sea. It typically terminates in the sands of the Thar Desert. While it enters Rajasthan through Hanumangarh and its waters can occasionally reach Pakistan during heavy floods, it never flows to the Arabian Sea. This characteristic distinguishes it from the state’s external systems.
Q15. Consider the following statements about the Ghaggar river:
I. It is commonly referred to as the ‘Dead River’ in local parlance.
II. The ancient archaeological site of Kalibangan is situated on its banks.
III. It originates from the western slopes of the Aravalli range in Rajasthan.
Which of the above statements is/are incorrect?
I. It is commonly referred to as the ‘Dead River’ in local parlance.
II. The ancient archaeological site of Kalibangan is situated on its banks.
III. It originates from the western slopes of the Aravalli range in Rajasthan.
Which of the above statements is/are incorrect?
Explanation
The Ghaggar River originates in the Shivalik Hills of Himachal Pradesh, not the Aravalli Range. It is indeed locally known as the ‘Dead River’ due to its seasonal and often dry nature. The historic site of Kalibangan, a major center of the Indus Valley Civilization, is located on its banks, highlighting the river’s importance in providing water to ancient settlements.
Q16. The flood plain of the Ghaggar river in the Hanumangarh and Sriganganagar districts is locally known by which of the following terms?
Explanation
The flat, fertile flood plain of the Ghaggar River in the northern districts of Hanumangarh and Sriganganagar is locally referred to as ‘Nali’. This region is agriculturally productive due to the silt deposited by the river during occasional flows. Understanding such local terminology is essential for studying regional geography and the specific impact of seasonal watercourses on the northern desert landscape.
Q17. The Banganga river, significant for eastern Rajasthan, originates from which of the following locations?
Explanation
The Banganga River originates from the Bairath Hills in the Jaipur Gramin district of Rajasthan. Historically linked to the Mahabharata, it flows through Jaipur, Dausa, and Bharatpur. While it was once a tributary of the Yamuna, it now often disappears in the plains of Bharatpur before reaching its destination, thus being reclassified as a river belonging to the internal drainage system.
Q18. The Banganga river is sometimes referred to as ‘Rindhit Nadi’ (Beheaded River). Which of the following concepts best explains this classification?
Explanation
The Banganga is termed a ‘Beheaded River’ or ‘Rindhit Nadi’ because its lower course has effectively been cut off from its original destination. Previously, it joined the Yamuna River in Uttar Pradesh. However, due to reduced water flow and siltation, it now terminates within the plains of Bharatpur. This shift from an open to an internal drainage pattern is a notable change.
Q19. Consider the following statements regarding the Gambhir river:
I. It originates from the hills of Karauli district.
II. It flows through Sawai Madhopur, Bharatpur, and Dholpur before entering Uttar Pradesh.
III. It directly joins the Yamuna river in Uttar Pradesh.
IV. The famous Panchana Dam is constructed on the confluence of its tributaries.
Which of the above statements is/are correct?
I. It originates from the hills of Karauli district.
II. It flows through Sawai Madhopur, Bharatpur, and Dholpur before entering Uttar Pradesh.
III. It directly joins the Yamuna river in Uttar Pradesh.
IV. The famous Panchana Dam is constructed on the confluence of its tributaries.
Which of the above statements is/are correct?
Explanation
The Gambhir river rises in the hills of Karauli district and flows through Sawai Madhopur, Bharatpur and Dholpur before entering Uttar Pradesh, where it joins the Yamuna. The Panchana Dam is built at the confluence of its tributaries. All four statements are correct.
