Our Country — India

UPSC has repeatedly tested India's latitudinal and longitudinal extent (8°4'N to 35°6'N; 68°7'E to 97°25'E), the significance of the Tropic of Cancer dividing India into tropical and subtropical zones, and India's total area (3.28 million sq km, 7th largest country). Know the exact coordinates of extremes: northernmost (Indira Col, 35°6'N), southernmost (Kanyakumari, 8°4'N), easternmost (Kibithu, Arunachal Pradesh, 97°25'E), westernmost (Ghuar Mota, Gujarat, 68°7'E). These factual anchors appear in MCQs testing geographical awareness. Do not conflate India's rank with Brazil or Australia—UPSC tests precision here.

UPSC frequently tests the list of India's 9 neighbouring countries (Pakistan, Afghanistan, China, Nepal, Bhutan, Bangladesh, Myanmar, Thailand, Sri Lanka via Palk Strait) and the distinction between land and maritime boundaries. Candidates must know: India shares land borders with 7 countries (Thailand only maritime); the longest border is with Bangladesh (~4,096 km); China border (3,488 km) is contested (LAC); Myanmar border (~1,468 km) is relevant to Northeast security questions. Trap: confusing whether Thailand shares a land or maritime boundary—it is purely maritime. Do not ignore the Palk Strait significance for Sri Lankan relations.

UPSC has tested the number of states (28) and UTs (8) as of the 2019-2020 curriculum (now 28 states, 8 UTs post-2019 reorganization; note Telangana's 2014 formation and Jammu & Kashmir's 2019 bifurcation). Know the capitals of major states and all UTs, especially Ladakh (Leh), Jammu & Kashmir (Srinagar for summer, Jammu for winter), Puducherry (Puducherry), Lakshadweep (Kavaratti), and Andaman & Nicobar Islands (Port Blair). Aspirants often miss updated UT structures—verify the latest administrative divisions. Do not memorize exhaustively; focus on geopolitically sensitive regions (Northeast, J&K, Ladakh) and island territories.

This section covers India's major physiographic regions: the Northern Mountains (Himalayas), Northern Plains (Indo-Gangetic), Peninsular Plateau, Coastal Plains, and Island Groups. UPSC extensively tests: the three Himalayan ranges (Greater, Lesser/Himachal, Shiwalik) and their characteristics; the Indo-Gangetic Plain's agricultural significance and mineral deposits; the Deccan Plateau's lava formation and drainage patterns; coastal plains' width variation (broader in east, narrower in west). Specific facts tested: the Himalayas are young fold mountains; the Deccan Plateau is the oldest landform; the Western Ghats are older than Eastern Ghats. Trap: confusing drainage directions (Deccan rivers flow eastward to Bay of Bengal, not westward). Negligible testing of island groups' detailed geology—skim.

UPSC tests specific mountain ranges and plateaus: the Himalayas' extent, highest peaks by region (K2 in Kashmir, Kangchenjunga in Sikkim), and role in climate moderation; the Eastern and Western Ghats as biodiversity hotspots and rain-shadow creators; plateaus like the Malwa, Chhota Nagpur, and Deccan Plateau with their mineral wealth and drainage systems. Know that the Western Ghats are a UNESCO World Heritage Site and biodiversity hotspot—increasingly tested in ecological questions. The Aravalli Range's erosion and impact on water availability in Rajasthan is contextually relevant. Do not memorize every minor range; focus on those with climatic, mineral, or strategic significance.

UPSC tests India's major river systems (Indus, Brahmaputra, Ganga, Narmada, Godavari, Krishna, Cauvery) and their characteristics: origination, course direction, and economic importance. Know that the Ganga is the longest river in the Indian territory (2,525 km); the Indus flows mainly through Pakistan; the Brahmaputra rises in Tibet and flows through Northeast India; peninsula rivers are shorter and seasonal. Trap: candidates confuse the Brahmaputra's course with the Ganga's or misstate river lengths. The Narmada and Godavari are tested for their N-S vs. E-W flow patterns. Do not over-invest in minor tributaries unless explicitly regional-relevance; prioritize the seven major systems.
