Q10 (IAS/2024) Geography › World Physical Geography › World physical mapping Official Key

Consider the following information : 1. Central Asia - Vosges - Fold mountain 2. Europe - Alps - Block mountain 3. North America - Appalachians - Fold mountain 4. South America - Andes - Fold mountain In how many of the above rows is the given information correctly matched ?

Result
Your answer: —  ·  Correct: B
Explanation

The correct answer is option B – only two rows are correctly matched.

Let's analyze each row:

**Row 1 (Central Asia - Vosges - Fold mountain): INCORRECT**
The Vosges mountains are located in Europe, specifically along the Rhine Rift, not in Central Asia[2]. While they are associated with Hercynian mountain building, their location is wrongly stated.

**Row 2 (Europe - Alps - Block mountain): INCORRECT**
The Alps are located in Europe[3], but the Alps are young fold mountains formed due to the collision between African Plate and the Eurasian Plate[4], not block mountains.

**Row 3 (North America - Appalachians - Fold mountain): CORRECT**
The Appalachians are located in North America[5] and the Appalachians are very old fold mountains that were formed even before the breakup of Pangaea[6].

**Row 4 (South America - Andes - Fold mountain): CORRECT**
The Andes are in South America[7] and the Andes are examples of Alpine fold mountains[8].

Therefore, only rows 3 and 4 are correctly matched, making the answer **two**.

This is a textbook 'Sitter' from the static Physical Geography syllabus. It directly tests the standard examples found in NCERT Class XI and GC Leong (Chapter 2). The question relies on the classic 'Swap Trap'—switching the characteristics of well-known European ranges (Alps vs Vosges). No current affairs knowledge was required; pure static revision wins here.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
Is the Vosges mountain range located in Central Asia?
Origin: Web / Current Affairs Fairness: CA heavy Web-answerable

Web source
Presence: 5/5
"Some other examples include: the Vosges and Black Forest mountains along the Rhine Rift in Europe"
Why this source?
  • Directly names the Vosges and locates them as being 'along the Rhine Rift in Europe'.
  • Placement in Europe contradicts the claim that the Vosges are in Central Asia.

Physical Geography by PMF IAS, Manjunath Thamminidi, PMF IAS (1st ed.) > Chapter 10: Types of Mountains > Continental Mountains > p. 133
Strength: 5/5
“• Coastal Mountains: The Rockies, The Appalachians, The Alpine chain, The Western & Eastern Ghats.• Inland Mountains: The Vosges and the Black Forest (Europe), The Kunlun, Tienshan, Altai mountains of Asia, The Urals of Russia, The Aravallis, the Himalayas, the Satpura, and the Maikal of India.”
Why relevant

Lists the Vosges explicitly among 'Inland Mountains' and associates it with 'Europe' alongside the Black Forest.

How to extend

A student could use this example-listing rule to check continent membership of other named ranges (if Vosges is listed with European ranges, likely not in Central Asia).

Physical Geography by PMF IAS, Manjunath Thamminidi, PMF IAS (1st ed.) > Chapter 10: Types of Mountains > Hercynian Mountains > p. 132
Strength: 5/5
“• These mountains originated during the upper Carboniferous to Permian Period in Europe (approximately 340 mya to 225 mya). E.g. Vosges and the Black Forest, Altai, Tien Shan mountains of Asia, Ural Mountains etc.”
Why relevant

Gives the Vosges as an example of Hercynian mountains that 'originated ... in Europe', linking Vosges to a European geologic group.

How to extend

One could extend the geologic/tectonic grouping: if Vosges is categorized with European Hercynian mountains, it's unlikely to be a Central Asian range.

Environment and Ecology, Majid Hussain (Access publishing 3rd ed.) > Chapter 4: BIODIVERSITY > europe and central Asia > p. 7
Strength: 4/5
“Mountains of Central Asia Te Plateau of Pamir, Tien Shan, Kun-Lun and Hindukush mountains region has great diversity of the species of fauna and fora.”
Why relevant

Provides a list of major mountains that define 'Central Asia' (Pamir, Tien Shan, Kun-Lun, Hindukush), showing which ranges are typically considered Central Asian.

How to extend

Compare the named Central Asian ranges with the Vosges — absence of Vosges from this Central Asia list suggests it is not usually classified there.

Strength: 3/5
“Most of the world's mountains are grouped in mountain ranges, such as the Himalayas in Asia, the Alps in Europe and the Andes in South America. Some of these ranges stretch for thousands of kilometres. Fig. 3.2 shows pictures of six mountains of the world. Fig. 3.3 brings them together to give a visual impression of their relative heights from top to bottom. Mount Everest (between Tibet (China) and Nepal) and Kanchenjunga (between Nepal and the Indian state of Sikkim) are the two highest peaks of the Himalayan range. Mount Aconcagua (in South America) is the highest peak of the Andes.”
Why relevant

Notes that most of the world's mountains are grouped by continent (e.g., Himalayas in Asia, Alps in Europe), implying continental classification is a common organizing principle.

How to extend

Apply the continent-grouping principle: determine which continental group (Europe vs Asia) Vosges is normally grouped with to assess the statement.
