Answer Key with Detailed Explanations

Answer 1: (c) 1 and 3 only​

Statement 1 is CORRECT: Venus has the longest rotation period among all planets, taking approximately 243 Earth days to complete one rotation on its axis, which is longer than its orbital period of 225 Earth days.​

Statement 2 is INCORRECT: Jupiter is known as the “King of Planets” or “Giant Planet” due to its massive size, not the “Winter Planet.” While Jupiter has very low temperatures around -150°C, this is not its primary designation.​

Statement 3 is CORRECT: Saturn has a density of approximately 0.687 g/cm³, which is less than water (1 g/cm³). Saturn would theoretically float in water due to its composition of primarily hydrogen and helium gases.​

Answer 2: (d) 1, 2 and 3​

Statement 1 is CORRECT: During the Summer Solstice around 21st June, the Tropic of Cancer (23.5°N) receives direct solar rays, marking the longest day in the Northern Hemisphere.​

Statement 2 is CORRECT: On Equinox days (21st March and 23rd September), the Sun is directly overhead at the Equator, resulting in equal day and night duration (approximately 12 hours each) across the globe.​

Statement 3 is CORRECT: During the Winter Solstice around 22nd December, the Tropic of Capricorn (23.5°S) is tilted toward the Sun and receives direct rays, marking the shortest day in the Northern Hemisphere.​

Answer 3: (a) A-2, B-3, C-4, D-1​

The correct matching of astronomical phenomena with dates:

• Summer Solstice (Northern Hemisphere): 21st June – longest day in the Northern Hemisphere

• Autumnal Equinox: 23rd September – beginning of autumn in Northern Hemisphere

• Winter Solstice (Northern Hemisphere): 22nd December – shortest day in Northern Hemisphere

• Vernal Equinox: 21st March – beginning of spring in Northern Hemisphere​

Answer 4: (b) Mohorovičić Discontinuity​

The Mohorovičić Discontinuity (Moho) is the boundary between Earth’s crust and mantle, discovered by Croatian seismologist Andrija Mohorovičić in 1909. It lies at approximately 5-8 km depth beneath oceanic crust and 25-60 km beneath continental crust. At this boundary, P-wave velocity increases abruptly from 6-7 km/sec to about 8 km/sec.​

Answer 5: (b) 1 and 2 only​

Statement 1 is CORRECT: The Gutenberg Discontinuity marks the boundary between the mantle and core at approximately 2,900 km depth, characterized by P-wave velocity decrease and S-wave disappearance.​

Statement 2 is CORRECT: The Conrad Discontinuity represents the transition between upper crust (SIAL) and lower crust (SIMA) at 15-20 km depth in continental regions.​

Statement 3 is INCORRECT: The Lehmann Discontinuity separates the outer core from the inner core, not the outer mantle from inner mantle. The Repetti Discontinuity marks the boundary between outer and inner mantle.​

Answer 6: (d) 1, 2 and 3​​

Statement 1 is CORRECT: P-waves (Primary waves) are longitudinal seismic waves that can travel through both solid and liquid layers of Earth, passing through crust, mantle, and core.​

Statement 2 is CORRECT: S-waves (Secondary waves) cannot travel through liquids and disappear at the Gutenberg Discontinuity, providing evidence that the outer core is liquid.​

Statement 3 is CORRECT: The Repetti Discontinuity marks the transition between the outer mantle (asthenosphere) and inner mantle (lower mantle) at approximately 700-1,000 km depth.​

Answer 7: (d) All four pairs​

All pairs are correctly matched:

• Krishna – Tungabhadra: Tungabhadra is a major right bank tributary of Krishna, formed by confluence of Tunga and Bhadra rivers​

• Godavari – Indravati: Indravati is a significant left bank tributary of Godavari, originating in Odisha​

• Yamuna – Chambal: Chambal is the largest tributary of Yamuna, originating from Vindhya Range​

• Brahmaputra – Manas: Manas is a major left bank tributary of Brahmaputra, originating in Bhutan​

Answer 8: (a) Andes – Rocky Mountains – Great Dividing Range – Himalayas​​

The correct order by length:

1. Andes: ~7,000 km (longest continental mountain range) – South America​

2. Rocky Mountains: ~4,830 km – North America​

3. Great Dividing Range: ~3,500 km – Australia​

4. Himalayas: ~2,400-2,500 km (highest but not longest) – Asia​​

Answer 9: (d) 1, 2 and 3​

Statement 1 is CORRECT: Lake Superior is the largest Great Lake by surface area at 31,700 square miles (82,100 km²) and is also the largest freshwater lake in the world by surface area.​

Statement 2 is CORRECT: Lake Michigan is the only Great Lake located entirely within the United States, bordered by Michigan, Wisconsin, Illinois, and Indiana.​

Statement 3 is CORRECT: The Great Lakes drain into the Atlantic Ocean through the St. Lawrence River system: Superior → Huron → Erie → Ontario → St. Lawrence River → Atlantic Ocean.​

Answer 10: (a) A-2, B-4, C-3, D-1​​

The correct matching:

• Amazon – South America: Second-longest river (6,400 km) with largest discharge globally​​

• Congo – Africa: Second-longest African river (4,700 km), deepest river in the world​

• Yangtze – Asia: Longest Asian river (6,300 km), flows through China​​

• Mississippi – North America: Longest North American river (3,730 km), flows through USA
