Geography mapping MCQ

The correct answer option is (d) More than one of the above. Detailed Explanation This question asks to identify the pair(s) that are not correctly matched. By examining each pair individually: 🟢 (a) Jog - Sharavati: This pair is correctly matched. Jog Falls (also known as Gerosoppa Falls) is one of India's highest plunge waterfalls, situated on the Sharavati River in the Shimoga district of Karnataka. 🔴 (b) Kapildhara - Kaveri: This pair is incorrectly matched. The Kapildhara waterfall is located near Amarkantak in Madhya Pradesh and is formed by the Narmada River, not the Kaveri River. 🔴 (c) Dhuandhar - Godavari: This pair is also incorrectly matched. The famous Dhuandhar Falls(known for its mist and dramatic marble gorges near Jabalpur, Madhya Pradesh) is formed by the Narmada River, not the Godavari River. Why Option (d) is Correct Because both Pair (b) and Pair (c) are incorrectly matched, multiple options meet the negative constraint of the question. Following standard BPSC exam evaluation patterns, this triggers Option (d) More than one of the above.

The correct answer option is (c) Lidder. Detailed Geographical Explanation The River Bank: Pahalgam, a world-famous hill station and tourist resort in the Anantnag district of Jammu & Kashmir, is nestled directly along the banks of the Lidder River (also known as the Liddar River). Hydrology of the Lidder: The Lidder is a 73-kilometre-long, fast-flowing mountain river. It originates from the high-altitude Kolahoi Glacier and the Sheshnag Lake. The scenic Lidder Valley, which frames the entire landscape of Pahalgam, is carved out by the continuous erosional and depositional action of this alpine river. The Confluence: After flowing through Pahalgam, the Lidder River moves downstream to meet the Jhelum River near Mirgund (Anantnag), making it a vital right-bank tributary of the Jhelum basin. Why the Other Options are Incorrect ❌ (a) Shyok: Known as the "River of Death," the Shyok is a major right-bank tributary of the Indus River. It flows entirely through the high-altitude region of Ladakh, hundreds of kilometres away from the Kashmir Valley. ❌ (b) Jhelum: While the Lidder eventually empties into the Jhelum, the main channel of the Jhelum does not pass directly through Pahalgam. Cities like Srinagar and Anantnag are located on the banks of the Jhelum. ❌ (d) Chenab: This river flows through the Jammu region (Kishtwar, Doda, and Ramban) and parts of Himachal Pradesh, completely separated from the Lidder Valley of Kashmir. Quick Mapping Check for 72nd BPSC Prelims BPSC frequently tests famous cities or tourist locations situated on specific river banks. Memorize these high-yield mountain setups: Pahalgam — Lidder River (Kashmir) Srinagar — Jhelum River (Kashmir) Leh — Indus River (Ladakh) Kargil — Suru River (Ladakh)

The correct answer option is (d) Krishna. Detailed Geographical Explanation The Island & Its Location: Divi Island (also widely referred to locally as Diviseema) is a low-lying, highly fertile deltaic riverine island situated in the Krishna district of Andhra Pradesh. Fluvial Geomorphology: As the main channel of the mighty Krishna River approaches the flat coastal plains of the East Coast to empty into the Bay of Bengal, it begins to bifurcate and break up into multiple downstream distributaries. The landmass trapped right inside these splitting channels and deltaic arms forms Divi Island. It hits its technical terminus point nearby at Divi Point (near Hamsaladivi). Ecological Significance: Because it is packed with rich alluvial deposits, Divi Island supports advanced canal irrigation networks. It is globally known for hosting a vast mangrove ecosystem cluster protected under the Krishna Wildlife Sanctuary. Why the Other Options are Incorrect ❌ (a) Mahananda: This is a major north-Indian tributary of the Ganga River flowing through Nepal, West Bengal, and Bihar, completely removed from coastal deltaic islands. ❌ (b) Vamsadhara: This is a smaller east-flowing river rising in Odisha and draining through northeastern Andhra Pradesh (Srikakulam), running far north of the Krishna basin. ❌ (c) Godavari: While the Godavari delta runs very close to the Krishna delta (collectively studied together as the KG Basin), its specific deltaic islands include areas like Konaseema, not Divi Island. Preparation Note for 72nd BPSC Prelims The 70th BPSC Prelims included multiple unconventional questions testing specific riverine topography and islands located across peninsular India. For your ongoing revision, ensure you map these major Indian riverine islands: Majuli Island — Brahmaputra River, Assam (The world's largest inhabited riverine island). Srirangam Island — Kaveri River, Tamil Nadu. Divi Island (Diviseema) — Krishna River, Andhra Pradesh. Bhavani Island — Krishna River (near Vijayawada), Andhra Pradesh

The correct answer option is (b) Pushkar Valley. Detailed Hydrological Breakdown The Specific Origin: The Luni River (the largest river in the Thar Desert region) originates in the western slopes of the ancient Aravalli Range. It forms as two distinct headwaters—the Saraswati(which flows out of Pushkar Lake) and the Sabarmati (which originates near Ajmer). The Confluence: These two alpine headstreams run parallel to each other and merge at Govindgarh inside the Pushkar Valley to officially create the main channel of the Luni River. From here, it flows in a southwest direction through the arid regions of Rajasthan and Gujarat. The Terminal Basin: The river is endorheic (has an internal drainage basin), meaning it never manages to reach the open ocean. Instead, after travelling a course of roughly 495 kilometres, it completely dissipates and empties into the marshy saline mudflats of the Rann of Kutch in Gujarat. Why the Other Options are Incorrect ❌ (a) Sambhar Lake: This is India's largest inland saltwater lake located near Jaipur. While the Luni river basin passes near this region, it is not the origin source of the river channel. ❌ (c) Sahni Salt Marsh: This is a factually incorrect option included by the BPSC board as a distractor. Key Value-Addition for the 72nd BPSC Prelims The Luni River is unique and highly favored by question-setters because of its water chemistry: It is a freshwater river in its upper reaches up until it hits Balotra (in Barmer, Rajasthan). From Balotra onwards, due to the high salt content of the desert soil it flows over, its water turns completely brackish/saline.
