Geography: India and World

Gondwana coal is indeed laminated and bituminous in nature, making statement 1 correct. However, statement 2 is incorrect because Gondwana coal is NOT completely free from moisture, sulphur, and phosphorus - it contains small amounts of these impurities though generally less than Tertiary coal. The first statement accurately describes the coal's physical structure.

Jammu hills receive adequate rainfall (>100 cm annually) due to their location and elevation. Mikir hills in Assam also receive high rainfall typical of the Northeast region. However, Zaskar range (in Ladakh) is a high-altitude cold desert receiving very low precipitation (<10 cm annually), well below 100 cm. Therefore only statements 1 and 2 are correct.

Statement 1 is incorrect because bajra (pearl millet) is primarily a kharif crop in India, sown at the onset of monsoon. Statement 2 is correct - maize is predominantly a kharif crop but is also cultivated as a rabi crop in some regions like Bihar and parts of Uttar Pradesh under irrigation. This dual-season flexibility is a characteristic of maize cultivation in India.

Shipki La is a Himalayan pass located in the Sutlej Valley, connecting Himachal Pradesh with Tibet. It is one of the important border trade routes between India and China. The pass is situated in the Kinnaur district of Himachal Pradesh where the Sutlej River flows, not in Chandra, Hunza, or Nubra valleys.

Statement 1 is incorrect - most Indian iron ore is hematite, not limonite. Statement 2 is correct - magnetite deposits occur in Dharwar and Cuddapah rock systems. Statement 3 is incorrect - sphalerite (zinc) and galena (lead) are found in sedimentary rocks of Rajasthan, Andhra Pradesh, and Gujarat, not primarily in pre-Cambrian rocks. Only statement 2 is correct.

Pair 1 is correct - Kottayam, Kollam, and Kozhikode (note: spelling corrected from 'Kojhikode') are major rubber-producing districts in Kerala. Pair 2 is correct - Kodagu, Chikmagalur, and Hassan in Karnataka are prime coffee-growing regions. Pair 3 is incorrect - major turmeric-producing districts are in Andhra Pradesh (Nizamabad, Kadapa) and Tamil Nadu (Erode), not the ones listed. Thus only pairs 1 and 2 match.

Statement 1 is correct - calcareous alluvial soils (rich in calcium carbonate) are found in the trans-Ganga and trans-Yamuna areas of western Uttar Pradesh, including north-eastern districts. Statement 2 is incorrect - calcareous sierozemic soils are typically found in dry, semi-arid regions of Rajasthan, Haryana, and parts of Gujarat, not in the coastal areas of South Orissa and North Andhra Pradesh which have different soil types.

The correct matching is: Dehar hydro project is in Himachal Pradesh (2), Gandhar thermal plant is in Gujarat (1), Kalinadi hydro project is in Karnataka (3), and Uran thermal plant is in Maharashtra (4). Option B presents this exact sequence: (a) 2 (b) 1 (c) 3 (d) 4.

All three pairs are correctly matched. Amarkantak in Madhya Pradesh has bauxite deposits, Barabil-Koira valley (spanning Odisha and Jharkhand) has rich hematite iron ore deposits, and Salem district in Tamil Nadu is known for magnesite deposits.

The question asks which statement is NOT correct. The Karanphuli river actually originates in the Chittagong Hill Tracts of Bangladesh (not Meghalaya) and flows through Bangladesh. The other statements about Sabarmati, Ghaghara, and Jhelum are geographically accurate.

Neora Valley National Park in West Bengal has an elevation range from about 150 feet to 10,500 feet, creating tropical, subtropical, temperate, and arctic climate zones within its boundaries. This altitudinal variation supports diverse ecosystems from tropical forests to alpine meadows.

Tuli is in Nagaland, Karbi-Langpi project is in Assam, Loktak project is in Manipur, and Naini Saini Airstrip is in Uttarakhand. Option C correctly matches all four locations to their respective states.
