Question

Which one of the following pairs is correctly matched?

	Geographical Region	Feature
a	Abyssinian Plateau	Arabia
b	Atlas Mountains	North-Western Africa
c	Guiana Highlands	South-Western Africa
d	Okavango Basin	Patagonia

Accepted Answer

Atlas Mountains - North-Western Africa Quick Verdict: The Atlas Mountains are a prominent fold mountain range which stretches across the Maghreb region (Morocco, Algeria, and Tunisia) in North-Western Africa. It acts as a massive natural wall, preventing the moisture of the Mediterranean Sea from reaching the Sahara Desert. Why are other options incorrect? Pair A: Located in East Africa, the Abyssinian Plateau is also called the Ethiopian Highlands because it primarily extends over Ethiopia, which was historically called Abyssinia. It is physically separated from the Arabian Peninsula by the Red Sea and the Gulf of Aden. Pair C: Located in South America (spanning Venezuela, Guyana, Suriname, and northern Brazil), the Guiana Highlands is one of the oldest geological formations on Earth and home to Angel Falls, the world's highest uninterrupted waterfall. Pair D: The Okavango Basin is a massive endorheic (inland) drainage basin in Southern Africa (primarily Botswana). On the other hand, Patagonia is a cold, semi-arid desert located at the southern tip of South America (shared by Argentina and Chile). 💡 The Examiner’s Mindset: The "Cross-Continent" Trap UPSC mapping questions frequently rely on phonetic or biome-based confusion to punish students who only memorize names without looking at an atlas. The Phonetic Trap: "Guiana" sounds almost identical to the "Gulf of Guinea" (which is in Africa). The examiner banked on students making this auditory connection to trick them into marking option (c). The Biome Swap: Okavango and Patagonia are both famous, remote geographical extremes, but the examiner aggressively swapped their continents to test true spatial awareness. Mains Concept Builder: The Okavango's Inland Delta The most "Mains-worthy" concept hidden in this question is the Okavango Basin. The two main rivers, the Cubango and Cuito, originate in Angola and flow to the south, where they become the border between Angola and Namibia. After flowing together they become the Okavango River that enters the Caprivi Strip in Namibia. After entering Botswana, the Okavango River flows into the Okavango Delta, a large swamp area and one of the world’s largest inland delta. Thus, instead of flowing into an ocean, the Okavango River empties directly onto the dry sands of the Kalahari Desert, creating a unique seasonal wetland oasis. This makes it a prime example of an endorheic (closed) drainage system and a globally critical biodiversity hotspot (a UNESCO World Heritage site). Understanding how wetlands survive in arid environments is highly relevant for GS3 (Environment and Ecology). 📝 Mains Practice Question (GS Paper 3 - Environment): What is an endorheic drainage basin? Using the Okavango Delta as a case study, discuss the ecological significance of inland wetlands situated in arid and semi-arid regions. (150 words, 10 marks)
