With reference to the hydrological characteristics and drainage network of the Krishna River system in Peninsular India, consider the following statements:

1. The Koyna, Bhima, and Musi rivers are all major left-bank tributaries joining the Krishna mainstem in its upper and middle reaches.
2. The Tungabhadra River, formed by the confluence of the Tunga and Bhadra streams in the Western Ghats, constitutes the largest right-bank tributary of the Krishna River.
3. The Ghataprabha and Malaprabha rivers originate in the Sahyadri range and join the Krishna River from its right bank.

Which of the statements given above are correct?

Show answer & explanation

Answer: 2 and 3 only

Answer

Statements 2 and 3 are correct. The Tungabhadra, Ghataprabha, and Malaprabha are right-bank tributaries of the Krishna River, while the Koyna is also a right-bank tributary (not left-bank). The Bhima and Musi are left-bank tributaries.
The choice specifying statements 2 and 3 only is correct. The Tungabhadra is the principal right-bank tributary formed by the confluence of the Tunga and Bhadra streams. Similarly, the Ghataprabha and Malaprabha originate in the Western Ghats and join the Krishna River from its right bank. Statement 1 is incorrect because the Koyna River is a right-bank tributary, whereas only Bhima, Musi, Munneru, and Dindi are left-bank tributaries.

Step-by-Step Solution

1
Analyze statement 1 regarding the bank orientation of Koyna, Bhima, and Musi rivers.
The Koyna River originates near Mahabaleshwar and flows southward before merging with the Krishna River at Karad from the right bank. The Bhima and Musi rivers join the Krishna from the left bank. Thus, statement 1 is incorrect.
Correct identification of left-bank vs. right-bank tributaries is necessary to evaluate statement 1.
2
Evaluate statement 2 concerning the origins and confluence of the Tungabhadra River.
The Tunga and Bhadra rivers originate in the Varaha Parvatha of the Western Ghats (Karnataka) and unite at Koodli to form the Tungabhadra River, which flows northeast to join the Krishna on its right bank near Alampur. Statement 2 is correct.
Verifies the geographic origin and tributary classification of the Tungabhadra.
3
Assess statement 3 regarding the Ghataprabha and Malaprabha tributaries.
Both the Ghataprabha and Malaprabha originate in the Western Ghats (Sahyadris) of Karnataka and flow eastwards to join the Krishna River from the right bank (at Almatti and Kudalasangama respectively). Statement 3 is correct.
Confirms the right-bank tributary status of Ghataprabha and Malaprabha.

The ocean floor consists of distinct relief zones extending from the mainland coast into the deep ocean. Arrange the following major ocean floor relief features in sequence starting from the coast moving seaward toward the deep ocean basin. Which order represents the correct spatial sequence from land to deep ocean?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct seaward sequence of ocean floor relief features starting from the continental coastline is Continental Shelf, followed by Continental Slope, Continental Rise, and finally Abyssal Plain.
Moving seaward from the continental shoreline, the ocean floor transitions sequentially across the continental margin to the deep ocean floor: Continental Shelf (shallow coastal platform) → Continental Slope (steep incline) → Continental Rise (gentle sediment apron at the base of the slope) → Abyssal Plain (flat deep ocean floor).

Step-by-Step Solution

1
Identify the feature closest to the coast
The Continental Shelf is the submerged extension of the continent adjacent to the shoreline.
It forms the shallow margin of the ocean basin closest to land.
2
Identify the transition zone descending steeply into deep water
The Continental Slope forms the steep drop-off directly seaward of the shelf break.
It marks the boundary between the continental block and the deep ocean basin.
3
Identify the thick depositional zone at the bottom of the slope
The Continental Rise is located at the base of the continental slope.
Sediments transported down submarine canyons accumulate here before reaching the abyssal floor.
4
Identify the deep flat ocean basin floor
The Abyssal Plain forms the vast, flat region of the deep ocean floor.
It represents the abyssal oceanic crust zone far from the continental landmass.

Question 52Question →

With reference to global atmospheric pressure belts and prevailing planetary wind systems, consider the following statements:
1. The Trade Winds blow from the Subtropical High-Pressure Belts towards the Equatorial Low-Pressure Belt, deflecting westward in both hemispheres due to the Coriolis effect.
2. The Westerlies are generally stronger and more persistent in the Southern Hemisphere than in the Northern Hemisphere due to the vast expanse of ocean and minimal landmass friction.

Which of the statements given above is/are correct?

Show answer & explanation

Answer: Both 1 and 2

Answer

Both 1 and 2
Both statements are correct. Trade winds move from the subtropical high-pressure belts to the equatorial low and are deflected westward by the Coriolis effect. Furthermore, because the Southern Hemisphere consists predominantly of ocean surface with very few land obstructions, the Westerlies encounter minimal friction and blow with much higher velocity and consistency than in the Northern Hemisphere.

Step-by-Step Solution

1
Analyze Statement 1 regarding Trade Winds direction and deflection.
Statement 1 is correct. Trade winds originate from the subtropical high-pressure cells (30∘ N30^\circ\text{ N} and 30∘ S30^\circ\text{ S}) and flow toward the equatorial low-pressure zone. The Coriolis force deflects them to the right in the Northern Hemisphere (Northeast Trades) and to the left in the Southern Hemisphere (Southeast Trades), causing a westward component in both cases.
Verifies atmospheric pressure gradient and Coriolis force deflection.
2
Analyze Statement 2 regarding the strength of Westerlies in the Southern Hemisphere.
Statement 2 is correct. In the Southern Hemisphere, the vast, uninterrupted ocean expanse offers negligible frictional resistance compared to the land-dominated Northern Hemisphere, allowing the Westerlies to attain high speeds and constancy (known as Roaring Forties, Furious Fifties, and Shrieking Sixties).
Verifies the effect of land-ocean distribution on surface atmospheric drag.

Answer: The Narmada river flows westward through a rift valley bounded by the Vindhya range to the north and the Satpura range to the south.; The Tapti river originates in the Betul district of Madhya Pradesh and drains into the Arabian Sea through the Gulf of Khambhat.

Answer

The correct statements are that the Narmada river flows westward through a rift valley between the Vindhya and Satpura ranges, and the Tapti river originates in the Betul district of Madhya Pradesh and drains into the Arabian Sea through the Gulf of Khambhat.
The Narmada river flows westward in a rift valley bounded by the Vindhyas in the north and Satpuras in the south. The Tapti river originates from the Satpura range in Betul district, Madhya Pradesh, and flows westward into the Gulf of Khambhat (Arabian Sea). Both of these statements correctly describe the major west-flowing peninsular rivers.

Step-by-Step Solution

1
Analyze the course and landform features of the Narmada River
Narmada rises from Amarkantak Plateau and flows west through a trough/rift valley between Vindhyan and Satpura ranges.
This confirms the structural valley path of Narmada.
2
Analyze the origin and mouth of the Tapti River
Tapti rises in Multai, Betul district of Madhya Pradesh, flowing westward into the Gulf of Khambhat (Arabian Sea).
This confirms the geographic facts regarding Tapti.
3
Evaluate coastal features (estuaries vs deltas) for west-flowing rivers
West-flowing rivers carry less silt across hard rocky terrain and form estuaries rather than deltas.
This refutes the assertion that Narmada and Tapti form extensive deltas.

Statements 1 and 2 are correct.
The correct answer includes statements 1 and 2 only. Stage 2 of the Demographic Transition Model features falling death rates and high birth rates, while the Ruhr basin and Pittsburgh region historically expanded around major coal reserves. Statement 3 is wrong because Mediterranean climates feature dry summers and wet winters, specializing in orchard fruits and viticulture rather than tropical plantation crops like sugarcane and rubber.

Step-by-Step Solution

1
Evaluate Statement 1 regarding demographic transition.
Statement 1 is correct. In Stage 2 of the Demographic Transition Model, improvements in healthcare, sanitation, and food supply lower the death rate rapidly while birth rates remain high, causing high population growth.
Accurate application of population geography models.

Question 56Question →

With reference to the atmospheric driving forces and mechanisms of the Indian Southwest Monsoon, consider the following statements:

1. The seasonal northward movement of the Inter-Tropical Convergence Zone (ITCZ) over the Ganga Plain establishes the thermal monsoon trough essential for drawing cross-equatorial winds.
2. The Tropical Easterly Jet (TEJ), positioned over the Indian Peninsula near 13∘N13^\circ\text{N} latitude during summer, facilitates upper-level divergence that reinforces the lower-level surface low-pressure system.
3. The intensification and position of the Mascarene High near the East African coast directly strengthen the cross-equatorial Somali Jet and the resultant moisture transport to the Indian subcontinent.
4. The Somali Jet is an upper-tropospheric westerly wind stream that impedes the inflow of moisture-laden Arabian Sea winds towards the Western Ghats.

Which of the statements given above are correct?

Show answer & explanation

Answer: 1, 2, and 3 only

Answer

Statements 1, 2, and 3 are correct, while statement 4 is incorrect because the Somali Jet is a low-level (not upper-tropospheric) cross-equatorial jet stream that transports massive moisture to India.
The option selecting statements 1, 2, and 3 only is correct because the northward movement of the ITCZ, upper-air divergence from the Tropical Easterly Jet, and the strong pressure gradient from the Mascarene High collectively establish the Indian southwest monsoon. The option incorrectly stating that the Somali Jet is an upper-tropospheric jet that impedes moisture is false, as the Somali Jet is low-level and strengthens monsoon rainfall.

Step-by-Step Solution

1
Analyze Statement 1 regarding ITCZ shift
Statement 1 is correct.
During northern summer, the ITCZ shifts northward over the Ganga plain (around 20∘N20^\circ\text{N}–25∘N25^\circ\text{N}), forming the equatorial trough of low pressure known as the monsoon trough.
2
Analyze Statement 2 regarding Tropical Easterly Jet (TEJ)
Statement 2 is correct.
The heating of the Tibetan Plateau gives rise to the Tropical Easterly Jet stream in the upper troposphere, creating upper-level divergence over South India which draws lower-level monsoon winds.
3
Analyze Statement 3 regarding Mascarene High
Statement 3 is correct.
A high-pressure cell near Madagascar (30∘S30^\circ\text{S}, 60∘E60^\circ\text{E}) acts as the Southern Hemisphere pressure origin; its strength correlates directly with strong cross-equatorial pressure gradients and monsoon rainfall.
4
Analyze Statement 4 regarding the Somali Jet
Statement 4 is incorrect.
The Somali (Findlater) Jet is a low-level jet stream (around 1.5 km1.5\text{ km} or 850 hPa850\text{ hPa}) off the horn of Africa, driving intense moisture-laden Arabian Sea winds towards western India, not an upper-tropospheric jet impeding moisture flow.

Consider the hydrological features, tributary orientations, and major water resource structures of the Cauvery River basin in Peninsular India. Which of the following statements regarding the Cauvery River system are correct?

Select all that apply

Show answer & explanation

Answer: Unlike most other Peninsular rivers, the Cauvery River basin receives rainfall from both the Southwest Monsoon during summer and the Northeast Monsoon during winter, resulting in a relatively less seasonal fluctuation in its discharge.; Along its upper course in Karnataka, the Cauvery River splits into two branches to enclose sacred riverine islands including Srirangapatna and Sivasamudram before cascading down the Sivasamudram Falls.

Answer

The statements confirming that the Cauvery River receives rainfall from both monsoons and that it forms the riverine islands of Srirangapatna and Sivasamudram are correct.
The Cauvery River system is unique among Peninsular rivers due to its regime: its upper basin is fed by the Southwest monsoon during summer and its lower basin by the Northeast monsoon during winter, which keeps its water flow comparatively stable. Furthermore, the river bifurcates and reunites in Karnataka to form the famous riverine islands of Srirangapatna and Sivasamudram.

Step-by-Step Solution

1
Analyze hydrological regime and monsoon interaction
The Cauvery catchment receives precipitation from both the Southwest (upper basin) and Northeast monsoons (lower basin), leading to sustained flow.

Answer

The statements stating that Hemavati and Arkavathi are left-bank tributaries, Bhavani and Amaravati are right-bank tributaries, and that the basin receives rainfall from both monsoon seasons are correct.
The statements confirming Hemavati and Arkavathi as left-bank tributaries, Bhavani and Amaravati as right-bank tributaries, and the dual-monsoon rainfall regime of the Cauvery catchment are all geographically accurate facts.

Step-by-Step Solution

1
Analyze the origin of the Cauvery River
The Cauvery River originates at Talakaveri in the Brahmagiri Hills of Kodagu, Karnataka. Trimbakeshwar is the source of the Godavari River.
Verifies geographical origin facts.
2
Classify tributaries by bank orientation
Left-bank tributaries include Harangi, Hemavati, Shimsha, and Arkavathi. Right-bank tributaries include Lakshmantirtha, Kabini, Bhavani, Noyyal, and Amaravati.
Confirms correct left-bank and right-bank classifications.
3
Evaluate the hydrological regime and monsoon pattern of the basin
Upper reaches receive summer rainfall from the Southwest monsoon, while lower reaches in Tamil Nadu receive heavy winter rainfall from the Northeast monsoon.
Confirms the unique dual-monsoon catchment nature of the Cauvery River.

Matches

Show answer & explanation

Answer

Yardang matches with Wind (Aeolian) action; Cirque matches with Glacial erosion; Stalagmite matches with Groundwater (Karst) deposition; Tombolo matches with Wave and coastal current deposition.
Each feature correctly matches its primary agent: Yardangs are created by aeolian erosion in arid landscapes; Cirques are glacial erosion basins; Stalalagmites develop via karst groundwater precipitation; Tombolos represent wave-driven coastal deposition linking islands to the mainland.

Step-by-Step Solution

1
Identify the formation agent for Yardang
Yardangs are carved by wind abrasion operating on alternating hard and soft rocks in deserts.
Attributing landform to aeolian processes.
2
Identify the formation agent for Cirque
Cirques are classic arm-chair hollows created by alpine glacier pluck and abrasion.
Attributing landform to glacial processes.
3
Identify the formation agent for Stalagmite
Stalagmites build up from cave floors via groundwater solution and drip deposition.
Attributing landform to karst subsurface processes.
4
Identify the formation agent for Tombolo
Tombolos are coastal ridges created by wave refraction and sediment deposition.
Attributing landform to marine depositional processes.

The Brahmaputra River system receives several prominent tributaries along its course through northeastern India. Among the following options, which river joins the Brahmaputra as a major left-bank tributary?

Show answer & explanation

Answer: Lohit River

Answer

The Lohit River is a major left-bank tributary of the Brahmaputra River system.
The Lohit River originates in the Tibet Autonomous Region (Kangri Karpo mountain range) and flows through Arunachal Pradesh into Assam, joining the Brahmaputra River at Sadiya from the left bank. Other prominent left-bank tributaries include the Dibang, Burhi Dihing, Dhansiri, and Kopili rivers.

Step-by-Step Solution

1
Identify the main course and flow direction of the Brahmaputra River in India.
The Brahmaputra flows westwards through Arunachal Pradesh and Assam.
Determining flow direction establishes which side corresponds to left-bank (south/east side) and right-bank (north side) tributaries.
2
Classify the given tributaries into left-bank and right-bank categories.
Subansiri, Kameng, and Manas join from the northern Himalayan slopes (right bank), while Lohit joins from the eastern mountains (left bank).
Accurate geographical classification distinguishes left-bank from right-bank rivers.
