Indian Geography MCQs with Answers & AI Explanation

The correct answer is A. - Why: In the Ganga basin, rainfall generally decreases as you move from west to east and from north to south. Western parts and northern fringe receive relatively more monsoon rain due to moisture supply and orographic effects; eastern and southern parts receive comparatively less. - Exam fact: Ganga basin rainfall peak often aligns with the central-northern stretch, showing a west-to-east decline. - Why others are wrong: - B implies increasing rainfall eastward and southward, which contradicts observed gradients. - C and D reverse the directional trend (west-to-east vs east-to-west or north-to-south vs south-to-north).

Explanation in exam terms

• Correct option A: El Niño refers to an abnormally warm ocean surface (sea–surface temperature anomaly) in the central/eastern Pacific, which disrupts the Walker Circulation and weakens the South West Monsoon in India.
• Why not B, C, D:
  • B: Not a warm air mass; it’s a sea-surface temperature anomaly.
  • C: Not a wind; it’s about ocean warming, not a periodic wind pattern.
  • D: Not a low-pressure centre; it’s a Pacific SST anomaly driving altered atmospheric circulation.

Exam fact: El Niño events commonly lead to deficient and delayed SW monsoon rainfall in India.

Explanation (Exam-oriented)

• The Veliconda (Velikonda) group of low hills is a structural part of the Eastern Ghats.
• These hills are part of the discontinuous Eastern Ghats belt running along the eastern peninsular plateau, mainly in Andhra Pradesh.

Correct answer: C

• Why correct: Veliconda Range lies in the Eastern Ghats, not in the Nilgiris, Western Ghats, or Cardamom Hills.
• Why others are wrong: Nilgiri Hills and Cardamom Hills are part of the Western Ghats; the Western Ghats lie to the west of the Deccan. Velikonda is distinctly eastern.

Exam fact: Eastern Ghats are older and more eroded than the Western Ghats and are structurally different (faulted and tilted blocks).

Explanation

• Correct option A: Dhrian – In the Thar Desert, mobile sand dunes that shift with wind are locally called dhrian (also spelled dhriyan). These are active dune systems typical of arid regions.
• Why others are incorrect:
• B. Daurs – deceptive ridges or dune-like features in some deserts, not the common shifting dunes of Thar.
• C. Dhoros – not the local term for Thar dunes.
• D. Dhaya – not the recognized local name.

The Jelep La pass is located in the Sikkim Himalaya.

• Why correct: Jelep La connects Sikkim in India with Tibet and lies in the eastern Himalayas, within Sikkim.
• Exam fact: It is a historic trade route and strategic pass between India and Tibet.

• Correct answer: Kerala and Tamil Nadu
• The Cardamom Hills are a part of the Western Ghats running along the border of Kerala and Tamil Nadu, especially in Idukki and Palakkad regions.
• Why others are wrong:
  • A) Karnataka and Tamil Nadu – not the main border for Cardamom Hills.
  • B) Karnataka and Kerala – stretches of Cardamom Hills lie near Tamil Nadu border, not Karnataka here.
  • D) Tamil Nadu and Andhra Pradesh – no, these hills are coastal-ward in Kerala–TN belt.
• Exam fact: They are part of the Western Ghats, a UNESCO-listed biodiversity hotspot important for spice cultivation.

Explanation (Exam-oriented):

• Correct choice: C — Mandav Hills are not in Maharashtra; they are located in Madhya Pradesh, near Mandav/Morena region.
• Other options lie in Maharashtra:
  • Balaghat Range — part of the Satpura–Maikal system extending into Maharashtra’s geography.
  • Harishchandra Range — a sub-range of the Western Ghats in Maharashtra.
  • Satmala Hills — a prominent hill range in northern Maharashtra (Awadhghat region).
• Exam fact: Western Ghats and Satpura ranges influence Maharashtra’s climate and biodiversity; Mandav Hills lie outside this state’s geographies.

Correct answer: A. Coromandel Coast

• The Coromandel Coast lies on the eastern coast of India, stretching from the Krishna delta in Andhra Pradesh to Cape Comorin (Kanyakumari) in Tamil Nadu, i.e., between Krishna delta and Cape Comorin.
• Other options are incorrect: North Circar is part of the eastern coast further north; Malabar Coast lies on the western coast; Konkan Coast is the western coastal belt between Mumbai and Goa.

Exam fact: The Coromandel Coast forms the dominant eastern littoral and hosts major ports like Chennai, a key UPSC/SSC factoid often tested.
