Ans > Sahyadri (Western Ghats)

Explanation: The Periyar Diversion Scheme collects the surplus water of the west-flowing Periyar river and diverts it through a tunnel across the Sahyadri (Western Ghats) to Tamil Nadu in the east.
Trans-Basin Water Transfer: Built in the late 19th century around the Mullaperiyar Dam, this historic engineering feat artificially forces a west-flowing river to cross the massive topographic barrier of the rain-drenched Western Ghats to supply the arid eastern rain shadow.

📌 Geomorphology • Rivers

Q.23) Which tributary of the Brahmaputra River presents a classic example of river capturing by taking over the waters of the Meghna river of Bangladesh?

Ans > Kapili

Explanation: Kapili, a tributary of the Brahmaputra, captured the waters of the Meghna river of Bangladesh, demonstrating the geomorphic process of river capturing.
Tectonic Influences: Facilitated by the tectonic uplift of the Shillong Plateau, the Kapili River aggressively eroded backwards (headward erosion), breaching the drainage divide and stealing the upper reaches of the Meghna.

📌 Geomorphology • Landforms

Q.24) Which geographical feature serves as physical evidence of the abandoned valley created after the Kapili River captured the waters of the Meghna River?

Ans > Lumding-Halflong Pass

Explanation: The Lumding-Halflong Pass serves as geological evidence of the abandoned valley left behind after the Kapili river captured the headwaters of the Meghna.
Understanding Abandoned Valleys: A wide, U-shaped “wind gap” without a corresponding stream proves a massive volume of water once flowed there. British engineers later utilized this naturally flat, eroded corridor to build a critical railway line.

📌 Geomorphology • Himalayas

Q.25) According to geologists, the Tsangpo river over Tibet historically took an easterly course and joined which major river system before headward erosion altered its path?

Ans > Irrawaddy River (Myanmar)

Explanation: During early days, the Tsangpo over Tibet took an easterly course and used to join the Irrawaddy River (Myanmar) through the Chindwin.
The Great Bend: This ancient route was violently severed by the tectonic uplift of the eastern Himalayas (Namcha Barwa), forcing the river into a 180-degree hairpin bend southward into India to form the modern Brahmaputra system.

📌 Hydrology • Punjab Rivers

Q.26) Traces of abandoned river channels between Montgomery and Multan demonstrate that which river drastically changed its old course about 250 years ago to join the Satluj near Sultanpur?

Ans > Beas

Explanation: About 250 years ago the Beas river changed its old course—traces of which remain between Montgomery and Multan—and joined the Satluj river near Sultanpur.
Dynamic Plains: The incredibly low gradient of the Indo-Gangetic plains makes rivers highly unstable. Around 1790, heavy flooding and sedimentation blocked the Beas’s original path to the Chenab, forcing it to merge with the Sutlej instead.

📌 Hydrology • Brahmaputra

Q.27) Historical hydrological records indicate that about 250 years ago, the Brahmaputra river flowing through Mymensingh naturally discharged its waters into which river?

Ans > Meghna River

Explanation: About 250 years ago, the Brahmaputra flowing through Mymensingh was discharging its massive waters directly into the Meghna River.
The 1787 Tipping Point: A catastrophic flood and earthquake caused the Teesta River to dump its massive sediment load into the Brahmaputra, choking the old channel through Mymensingh and forcing the river to carve a new path south.

📌 Hydrology • Delta

Q.28) Following tectonic and depositional shifts, the Brahmaputra river straightened its course and joined the Ganga (Padma) River to form a massive new stream known as:

Ans > Jamuna

Explanation: In due course, the Brahmaputra straightened its course southward and joined the Ganga (Padma) River, forming a colossal new stream called the Jamuna.
Braided River Characteristics: Carrying a gargantuan load of Himalayan sediment, the relatively young Jamuna is a highly unstable braided river, creating temporary sand islands (chars) in a channel up to 15km wide during monsoons.

📌 Tectonics • Northern Plains

Q.29) The shifting of river courses in the northern plains of India is attributed to several geomorphic phenomena. Which of the following tectonic uplifts is noted as a primary cause for these river shifts?

Ans > Upliftment of the Potwar Plateau (Delhi-Sirhind Plateau)

Explanation: The shifting of river courses is prominently caused by the upliftment of the Potwar Plateau (Delhi-Sirhind Plateau), along with the downwarping of the Malda Gap.
The Great Drainage Divide: Acting as the master drainage divide, the slow tectonic tilting of the Delhi Ridge over millennia separated the Indus (west) and Ganga (east) basins, and is believed to have caused the drying of the legendary Saraswati river.

📌 Geology • Plateaus

Q.30) The Chotanagpur Plateau is a complex geological formation sprawling over parts of West Bengal, Jharkhand, and Chhattisgarh. It is predominantly composed of which basal rock types?

Ans > Archaean granite and gneiss with patches of Dharwar rocks

Explanation: The Chotanagpur Plateau is fundamentally composed of ancient Archaean granite and gneiss rocks with patches of highly metalliferous Dharwar (mica-schists) rocks, as well as Gondwana coal basins.
The Mineral Heartland: As one of the oldest, most stable landmasses (the Peninsular Shield), the inclusion of Dharwar rocks makes this plateau the “Ruhr of India,” holding the nation’s richest reserves of iron ore, copper, and mica.
