Consider the following pairs :

Peak Mountains
1. Namcha Barwa Garhwal Himalaya
2. Nanda Devi Kumaon Himalaya
3. Nokrek Sikkim Himalaya

Which of the pairs given above is/are correctly matched?

  1. A1 and 2
  2. B2 only
  3. C1 and 3
  4. D3 only
Show answer

Answer: (B) 2 only

The answer is (B) Only Pair 2 is correct.

Pair 1 is WRONG:
Namcha Barwa is in Tibet (far eastern Himalayas), NOT in Garhwal Himalaya (which is in Uttarakhand).

Pair 2 is CORRECT:
Nanda Devi (India's 2nd highest peak, 7,817m) is in the Kumaon Himalayas, Chamoli district, Uttarakhand.

Pair 3 is WRONG:
Nokrek Peak is the highest peak of Garo Hills in MEGHALAYA, NOT Sikkim Himalaya. Sikkim has peaks like Kangchenjunga — totally different region.

Tip:
These "match the pairs" questions often rely on you confusing eastern and western Himalayan features.

Why this was asked

Nanda Devi is India's second highest peak at 7,817 meters and lies in Uttarakhand's Kumaon Himalayas.

UPSC is testing whether students can distinguish between different Himalayan ranges (Garhwal, Kumaon, Sikkim) and avoid confusing peaks from completely different mountain systems like Meghalaya's Garo Hills.

The question checks knowledge of specific peak locations across India's diverse mountain ranges, from the main Himalayas to northeastern hill ranges.

Himalayan Regional Divisions

Geography Garhwal Himalaya Kumaon Himalaya Sikkim Himalaya

Himalayan Regional Divisions: West to East Classification

Must know

Himalayas are divided into 5 longitudinal regions from west to east

Kumaon Himalaya lies in Uttarakhand between rivers Kali and Sutlej

Garhwal Himalaya is in western Uttarakhand, west of river Kali

Good to know

Sikkim Himalaya is a separate eastern section in Sikkim state

Regional Framework

The Himalayan mountain system extends over 2,500 km and is traditionally divided into longitudinal sections based on river valleys and political boundaries. Each section has distinct geological features and major peaks.

Exam traps

Trap: Namcha Barwa is in Tibet/Arunachal border, NOT Garhwal - students confuse eastern vs western peaks

Trap: Nokrek Peak is in Meghalaya Garo Hills, NOT Sikkim Himalayas - completely different mountain system

Trap: Both Garhwal and Kumaon are in Uttarakhand but are separate Himalayan sections

Trap: River Kali divides Garhwal (west) from Kumaon (east) within Uttarakhand

Major Himalayan Peaks

Geography Namcha Barwa Nanda Devi Peak

Major Himalayan Peaks: Heights & Regional Location

Must know

Nanda Devi (7,817m) is India's 2nd highest peak in Kumaon Himalayas

Namcha Barwa (7,782m) lies on Tibet-Arunachal border, not in Garhwal

Kangchenjunga (8,586m) is world's 3rd highest, located in Sikkim Himalayas

Peak Classification

Himalayan peaks above 7,000m are distributed across different regional sections. Location matters more than height for UPSC - knowing which peak belongs to which Himalayan division is frequently tested.

Peak Locations - Quick Facts

Nanda Devi lies in Chamoli district, Uttarakhand - part of Nanda Devi Biosphere Reserve

Namcha Barwa marks the eastern syntaxial bend where Himalayas curve south into Myanmar ranges

Trishul (7,120m) is another major Kumaon Himalaya peak near Nanda Devi

Most 8,000m+ peaks lie in Nepal and Karakoram (Pakistan), not Indian Himalayas

Exam traps

Trap: Nanda Devi is 2nd highest in India but students often think it's the highest (that's Kangchenjunga)

Trap: Namcha Barwa sounds Indian but is actually on Tibet side of border

Trap: Don't confuse Garhwal peaks (Kamet, Kedarnath) with Kumaon peaks (Nanda Devi, Trishul)

Trap: Peak heights change slightly in different sources - focus on regional location for UPSC

Nokrek Peak & Garo Hills

Geography Nokrek

Nokrek Peak: Highest Point of Garo Hills, Meghalaya

Must know

Nokrek Peak (1,412m) is the highest point of Garo Hills in Meghalaya

NOT part of Himalayas - belongs to Meghalaya Plateau (ancient landmass)

Good to know

Located in Nokrek National Park, part of Nokrek Biosphere Reserve

Geographic Context

Nokrek Peak is part of the Meghalaya Plateau, which is an ancient block of the peninsular India, not the young-fold Himalayan system. This distinction is crucial for UPSC questions that test regional classification.

Exam traps

Major Trap: Nokrek is in Meghalaya, NOT Sikkim - students confuse northeastern hill states

Trap: Nokrek is part of peninsular plateau, NOT young-fold Himalayas

Trap: Don't confuse Garo Hills (Meghalaya) with Garhwal Himalayas (Uttarakhand) - similar names

Sikkim Himalaya Major Peaks

Geography Sikkim Himalaya

Sikkim Himalaya: Kangchenjunga & Eastern Himalayan Features

Must know

Kangchenjunga (8,586m) is the highest peak in Sikkim Himalayas

Sikkim Himalayas lie between Teesta and Dihang rivers

Good to know

Region includes parts of Sikkim, Darjeeling, and eastern Nepal

Regional Boundaries

The Sikkim Himalaya section extends from River Teesta in the west to River Dihang in the east. Kangchenjunga massif dominates this region, forming the India-Nepal border.

Sikkim Himalaya Features

Nathu La Pass (4,310m) connects Sikkim with Tibet - historic Silk Route point

Zemu Glacier is the largest glacier in eastern Himalayas, flows from Kangchenjunga

Region receives heavy monsoon rainfall making it prone to landslides

Rhododendrons are the characteristic vegetation - Sikkim has 40+ species

Exam traps

Trap: Kangchenjunga belongs to Sikkim Himalayas, NOT Nokrek which is in Meghalaya

Trap: Sikkim Himalayas include eastern Nepal peaks too, not just Sikkim state

Trap: Don't confuse Teesta River (Sikkim boundary) with Tista River (different spelling/region)
