Indian Geography Mixed Practice — MCQs with Answers (Set 21)

The Montreux Record lists Ramsar sites where ecological character has changed or may change. India’s sites on it are Keoladeo (since 1990) and Loktak (since 1993). Sukhna is a newly added site, and Chilika is not named on the list.

Combining multiple criteria lets the system capture real ecological complexity; two forests with similar rainfall can still differ sharply in species composition and structure.

The correct answer is The volcanic arc. Barren Island is a volcano on an arc that links Sumatra and Myanmar. The foredeep, accretionary prism and back-arc basin are other parts of a subduction system. Memory hook: volcano equals arc.

Lakshadweep sits on the Laccadive-Chagos Ridge, believed to be the volcanic trace of the Reunion hotspot, left behind as India drifted north over it after separating from Madagascar and the Seychelles.

Lakshadweep’s islands formed from coral growth on a submarine ridge, while the Andaman and Nicobar Islands are the exposed peaks of a submerged mountain range — two very different origins.

Kavaratti is the capital of Lakshadweep, located about 220 miles west of the Malabar Coast.

Lakshadweep is India’s smallest Union Territory, with a total land area of only about 32 square kilometres, though scattered over 30,000 sq km of sea.

The Andaman and Nicobar Islands are a sunken mountain range’s exposed peaks, while Lakshadweep formed from coral growth on a submerged plateau — two very different origins.

On 26 December 2004, an undersea megathrust earthquake off Sumatra triggered a tsunami that struck the islands, killing over 2,000 people and leaving roughly 40,000 homeless.

The Ten Degree Channel separates the Andaman group from the Nicobar group; Saddle Peak on North Andaman, about 733 metres, is the whole group’s highest point.

The correct answer is Barren Island. It lies in the Andaman Sea and has erupted many times. Saddle Peak, Ross Island and Havelock Island are not volcanoes. Memory hook: Barren is the bare, active one.

The Andaman and Nicobar Islands are geologically the submerged extension of the Arakan Yoma mountain range of Myanmar, with only the highest ridges staying above the sea.

The Vindhya Range runs roughly 1,086 km, from Gujarat across Madhya Pradesh to near Varanasi in Uttar Pradesh, forming the southern edge of the Malwa Plateau.

The Vindhya Range splits into the Kaimur Range, running north of the Son river, and a southern branch running between the Son and Narmada rivers to meet the Satpura Range at the Maikal Range (Amarkantak Plateau).

Legend holds that the Vindhya grew taller each day out of envy of Mount Meru, until the sage Agastya made it bow before him — and it stayed bowed even after he left on pilgrimage and never returned, explaining its modest height.

The correct answer is The Vindhya Range is the mountain/escarpment landform; the Vindhyan Rock System is the sedimentary rock formation named after it. One is a line of hills. The other is a stack of sedimentary rock, mostly sandstone, shale and limestone. Memory hook: range is landform, system is rock.

The Vindhya Range traditionally marks the boundary between the Indo-Gangetic Plains of North India and the Peninsular Plateau of South India.

NCERT places the Satpura along the northern edge of the Deccan. The Satpura Tiger Reserve lies in Madhya Pradesh. Its tiger habitat joins forests in Maharashtra. The Himalaya runs far to the north.

NCERT lists the Maikal range and the Mahadeo hills with the Satpura along the Deccan’s northern edge. The other options are far away, in the south, the north or the north-east.

Correct as keyed: a block mountain (horst). Block ranges rise where the crust breaks along faults. The Himalaya instead formed by collision and folding as India met Eurasia. The key for the Satpura itself rests on the question bank, not on a saved source.

Dhupgarh, at 1,352 metres, is the highest point in Madhya Pradesh. It lies near Pachmarhi, the only hill station in the state. Anamudi is in the Western Ghats, Guru Shikhar is in the Aravalli, and Doddabetta is in the Nilgiri hills. CDS-II 2019 asked this match.
