Items

Tropical Easterly Jet Stream (TEJ)
Subtropical Westerly Jet Stream (STWJ)
Inter-Tropical Convergence Zone (ITCZ)
Southern Oscillation

Matches

Show answer & explanation

Answer

The Tropical Easterly Jet Stream matches with establishing over the southern Indian Peninsula in summer and steering tropical depressions; the Subtropical Westerly Jet Stream matches with withdrawing north of the Himalayas before monsoon onset; the Inter-Tropical Convergence Zone matches with shifting over the Indo-Gangetic Plain to form the monsoon trough; and the Southern Oscillation matches with the pressure seesaw between the Pacific and Indian Oceans.
Each atmospheric component is correctly paired with its driving mechanism in the monsoon system: the Tropical Easterly Jet Stream steers summer rain depressions; the Subtropical Westerly Jet Stream retreats north of the Himalayas prior to onset; the ITCZ shifts northward over the Gangetic Plain as the monsoon trough; and the Southern Oscillation reflects interannual ocean-atmosphere pressure variations.

Step-by-Step Solution

1
Analyze the role of the Tropical Easterly Jet Stream (TEJ)
TEJ is an upper-tropospheric wind system originating from thermal heating over Tibet during summer, positioned near 14°N over peninsular India.
It facilitates the entry and movement of monsoon depressions into northern and central India.
2
Identify the behavior of the Subtropical Westerly Jet Stream (STWJ)
STWJ shifts north of the Himalayas near the end of May.
The vacating of STWJ from the northern Indian plains allows the equatorial low-pressure system to surge rapidly northward.
3
Examine the seasonal movement of the Inter-Tropical Convergence Zone (ITCZ)
The ITCZ moves to 20°–25°N over the Gangetic Plain in July, becoming the monsoon trough.
This low-pressure trough attracts the cross-equatorial southeast trade winds, which turn into southwest monsoons.
4
Define the ocean-atmosphere phenomenon known as the Southern Oscillation
Southern Oscillation measures pressure variations across the Pacific and Indian Oceans.
It acts as a primary indicator of global climate variability affecting monsoon strength.

In the industrial geography of India, aluminum smelting plants such as those located at Hirakud, Renukoot, and Korba demonstrate distinct location dynamics. Which of the following factors primarily dictates the location of aluminum smelting units near major power generation stations?

Show answer & explanation

Answer: The extraction of aluminum via electrolytic reduction is exceptionally energy-intensive, making the continuous availability of cheap electrical power the primary cost-determining factor.

Answer

The extraction of aluminum via electrolytic reduction is exceptionally energy-intensive, making the continuous availability of cheap electrical power the primary cost-determining factor.
Aluminum smelting is a classic example of a power-intensive industry. Because electrical energy constitutes a major fraction of the total manufacturing cost, smelters are sited where abundant and reliable electric power is available, such as near major hydroelectric dams or thermal power complexes.

Step-by-Step Solution

1
Examine the two-stage manufacturing process of aluminum in India.
Stage 1 converts bauxite to alumina (raw material oriented), and Stage 2 uses electrolytic reduction to extract aluminum metal (power oriented).
The smelting stage consumes massive amounts of electricity, accounting for 30% to 40% of total production cost.
2
Analyze the spatial distribution of major Indian smelters relative to energy projects.
Facilities at Hirakud (Odisha) and Renukoot (Uttar Pradesh) were purposely located adjacent to major hydroelectric projects (Hirakud Dam) and thermal power hubs (Rihand complex).
Proximity to reliable, low-cost power lowers operational expenses significantly compared to siting purely near bauxite mines.

Which of the following climatic types according to Köppen's scheme of classification correctly represents the Coromandel Coast of Tamil Nadu, which receives the major portion of its rainfall during the winter season from the retreating monsoon?

Show answer & explanation

Answer: Monsoon with dry summer (AsAs)

Answer

Monsoon with dry summer (AsAs)
Under Köppen's scheme, the symbol 'AA' represents tropical climate where the average temperature of the coolest month is 18∘C18^\circ\text{C} or higher. The lowercase letter 'ss' denotes a dry summer season. The Coromandel Coast remains dry during the South-West summer monsoon because it lies parallel to the Bay of Bengal branch and in the rain-shadow area of the Western Ghats, but receives substantial winter rainfall from the North-East monsoon, making AsAs the exact designation.

Step-by-Step Solution

1
Identify the geographical region and seasonal rainfall pattern specified in the question.
The region is the Coromandel Coast of Tamil Nadu, which experiences dry summers and receives most precipitation in winter from retreating monsoon winds.
Köppen's climate classification assigns letter symbols based on temperature and seasonal precipitation patterns.
2
Map the precipitation characteristics to Köppen's climatic letters.
The letter 'AA' denotes a tropical humid climate, and lowercase 'ss' indicates a dry summer season.
Combining 'AA' and 'ss' yields AsAs, which defines the rainfall profile of coastal Tamil Nadu.

Question 230Question →

Which of the following atmospheric and oceanic features actively contribute to strengthening the South-West Monsoon system over the Indian subcontinent?

Select all that apply

Show answer & explanation

Answer: The upper-tropospheric anticyclone formed over the intensely heated Tibetan Plateau during summer; The semi-permanent high-pressure cell known as the Mascarene High near Madagascar in the Southern Indian Ocean

Answer

The mechanisms that actively strengthen the South-West Monsoon are the upper-tropospheric anticyclone over the heated Tibetan Plateau and the Mascarene High in the Southern Indian Ocean.
The South-West Monsoon system relies on two critical drivers: the upper-tropospheric anticyclone over the Tibetan Plateau, which generates the Tropical Easterly Jet and maintains monsoon circulation, and the Mascarene High in the Southern Indian Ocean, which drives moisture-rich cross-equatorial winds into the Indian subcontinent.

Step-by-Step Solution

1
Analyze thermal and dynamic drivers over Asia during summer
Intense thermal heating over the high-altitude Tibetan Plateau creates a thermal ridge and high-pressure anticyclone in the upper troposphere (~200 hPa). Air diverging from this anticyclone forms the Tropical Easterly Jet (TEJ), which reinforces the low-level monsoon trough over India.
Tibetan heating is a major dynamic thermal engine for monsoon onset and maintenance.
2
Analyze oceanic pressure hubs in the Southern Hemisphere
The Mascarene High, positioned at ~30°S near Madagascar, serves as the pressure gradient source pushing southeast trade winds north across the equator. Upon crossing the equator, these winds deflect right due to the Coriolis force, becoming the moisture-laden South-West Monsoon winds.
A strong Mascarene High directly enhances cross-equatorial flow and monsoon rainfall strength.
3
Evaluate Pacific and ITCZ anomalous influences
El Niño creates descending air over the western Pacific and Indian Ocean, weakening monsoon winds. Similarly, a southward shift of the ITCZ during peak summer causes a break in the monsoon over Northern India.
Both factors suppress, rather than strengthen, South-West Monsoon activity.

Question 232Question →

In India, the spatial distribution of nitrogenous fertilizer manufacturing units underwent a major locational shift following the expansion of cross-country natural gas pipelines like the Hazira-Vijaypur-Jagdishpur (HVJ) network. Which of the following factors best explains why modern urea plants are increasingly located in inland agricultural regions along pipeline routes rather than being confined near coalfields or coastal crude oil refineries?

Show answer & explanation

Answer: Pipeline transport of natural gas provides flexible raw material access, allowing plants to locate closer to major agricultural consuming markets and reduce finished fertilizer distribution costs.

Answer

Pipeline transport of natural gas provides flexible raw material access, allowing plants to locate closer to major agricultural consuming markets and reduce finished fertilizer distribution costs.
The correct option explains that pipeline transportation of natural gas frees fertilizer production from raw-material site lock-in. Because finished fertilizer bags are bulky and expensive to transport across long distances, establishing plants near major agricultural consumption regions in Northern and Central India minimizes overall supply chain and freight costs.

Step-by-Step Solution

1
Analyze the historical feedstock shift in the Indian fertilizer industry.
Early nitrogenous fertilizer plants depended on coal, coke oven gas, or petroleum naphtha, tying units to coalfields (e.g., Sindri) or coastal oil refineries.
Heavy, localized raw materials dictated initial plant placement.
2
Examine the impact of cross-country gas pipelines.
Pipelines like HVJ efficiently transport natural gas across vast distances directly into agricultural heartlands such as Uttar Pradesh, Madhya Pradesh, and Rajasthan (e.g., plants at Jagdishpur, Aonla, Babrala).
Gas pipelines decouple processing locations from raw material extraction sources.
3
Identify the primary economic driver for market-oriented inland plant placement.
Bagged urea is bulky and expensive to haul by rail or road over long distances; placing production hubs near intensive farming zones minimizes overall freight and distribution expenses.
Market proximity optimizes logistics for weight-gaining finished goods delivery.

Which of the following statements regarding the physical geography and relief features of the Peninsular Plateau and Coastal Plains of India are correct?

Select all that apply

Show answer & explanation

Answer: The Meghalaya Plateau is an eastern extension of the Peninsular Plateau, separated from the Chota Nagpur Plateau by a structural fault gap.; The Western Coastal Plain is a submerged coast featuring narrow margins and estuaries, providing favorable conditions for natural deepwater ports.

Answer

The correct statements are that the Meghalaya Plateau is an eastern structural extension of the Peninsular Plateau separated by the Malda fault gap, and that the Western Coastal Plain is a submerged coast with narrow margins and estuaries favorable for deepwater ports.
The statement regarding the Meghalaya Plateau is accurate because it is a structural extension of the Peninsular Plateau formed by downfaulting between the Rajmahal Hills and Garo Hills (Malda gap). Furthermore, the statement regarding the western coast is correct because it is a submerged coastal line creating narrow plains, estuaries, and natural deep harbors.

Step-by-Step Solution

1
Evaluate the geological connection of the Northeastern hill plateau.
Geologically, the Meghalaya and Karbi Anglong plateaus are outliers of the Peninsular block, separated from the Rajmahal Hills / Chota Nagpur Plateau by the Malda (Garo-Rajmahal) gap.
This establishes the structural continuity of the Peninsular shield.
2
Assess the physiographic nature of the Western Coastal Plain.
The Western Coastal Plain is a prime example of a submerged coastal plain, resulting in narrow coastal strips, steep continental gradients, estuaries, and natural deep harbors.
This contrasts with the emergent, deltaic, and broader Eastern Coastal Plain.
3
Examine the spatial arrangement of southern hill ranges around Palghat Gap.
From north to south, the sequence is Nilgiri Hills → Palghat Gap → Anaimalai Hills → Shencottah Gap → Cardamom Hills. The Cardamom Hills lie south of Palghat Gap.
This disproves the assertion that Cardamom Hills lie north of the Palghat Gap.
4
Analyze Northern Plains zonal relief features from north to south.
The sequence from north to south along the Himalayan foothills is Shiwalik → Bhabar (pebble zone) → Terai (marshy re-emergence zone) → Bangar (older alluvium) → Khadar (newer floodplains).
This refutes the assertion claiming Bhabar lies south of Terai.

Show answer & explanation

Answer: Adoption of artificial humidification technology, expansion of the electricity power grid, and growth of interior market demand

Answer

Adoption of artificial humidification technology, expansion of the electricity power grid, and growth of interior market demand
The cotton textile industry is a non-weight-losing industry (1 ton of raw cotton produces approximately 1 ton of cloth). Consequently, it is a footloose industry that can be located near raw materials, market centres, or cheap power sources. The development of artificial humidifiers enabled mills to function in dry interior climates, while widespread electrification and expanding regional markets led to decentralization across Tamil Nadu (Coimbatore), Uttar Pradesh (Kanpur), and Punjab (Ludhiana).

1
Analyze historical locational factors of the cotton textile industry
Initially localized in Mumbai and Ahmedabad due to raw cotton availability, humid climate (preventing yarn breakage), port facilities, and capital access.
Understanding initial concentration factors helps identify what changed to allow dispersion.
2
Identify key technological and infrastructure developments facilitating decentralization
Artificial humidification solved the climate constraint, power development (hydro/thermal) freed mills from coal/port dependence, and market expansion made footloose location viable.
Cotton yarn/cloth is a non-weight-losing material, making proximity to market and cheap power primary drivers.

Consider the following statements regarding the structural and relief characteristics of the Peninsular Plateau of India:

1. The Western Ghats are continuous and can be crossed through passes only, whereas the Eastern Ghats are discontinuous and dissected by major east-flowing rivers.
2. The average elevation of the Western Ghats decreases progressively from north to south.
3. The Eastern Ghats join the Western Ghats at the Nilgiri Hills.

Which of the statements given above are correct?

Show answer & explanation

Answer: 1 and 3 only

Answer

Statements 1 and 3 are correct.
The Western Ghats form a continuous relief bar crossed only via specific passes, whereas the Eastern Ghats are discontinuous due to severe river dissection. The two ranges join at the Nilgiri Hills. The statement asserting a northward-to-southward decrease in elevation for the Western Ghats is false because the elevation actually increases southwards.

Step-by-Step Solution

1
Analyze the structural continuity and drainage impacts on both Ghats (Statement 1).
Statement 1 is true. The Western Ghats form a continuous escarpment traversed primarily through mountain passes (e.g., Thal Ghat, Bhor Ghat, Palghat). In contrast, the Eastern Ghats are highly fragmented and eroded by major east-flowing rivers such as the Mahanadi, Godavari, Krishna, and Kaveri.
Denudational processes and river incision have breached the Eastern Ghats into separate hill massifs.
2
Evaluate the elevation gradient of the Western Ghats from North to South (Statement 2).
Statement 2 is false. The average elevation of the Western Ghats increases southward.
The highest peaks of the Peninsular region, such as Anamudi (2,695 m) and Doddabetta (2,637 m), are located in the southern section of the Western Ghats.
3
Identify the geographical convergence zone of the Western and Eastern Ghats (Statement 3).
Statement 3 is true. The Eastern Ghats meet the Western Ghats at the Nilgiri complex.
The Nilgiri mountain block acts as the knot where both mountain systems converge.

During the South-West monsoon season in India, a temporary interruption in rainfall known as a 'monsoon break' occurs when the low-pressure monsoon trough shifts northward toward the Himalayan foothills. Which of the following spatial rainfall distribution patterns best characterizes the Indian subcontinent during such a break period?

Show answer & explanation

Answer: Heavy rainfall becomes concentrated along the Himalayan foothills and parts of Northeast India, while rainfall decreases significantly over the central and northern Indian plains.

Answer

Heavy rainfall becomes concentrated along the Himalayan foothills and parts of Northeast India, while rainfall decreases significantly over the central and northern Indian plains.
During the months of July and August, when the monsoon trough shifts northward to lie close to the foothills of the Himalayas, a 'break' in the monsoon occurs over major parts of India. During this phase, rainfall decreases substantially over the central, western, and northern plains, whereas heavy rainfall becomes concentrated along the Himalayan foothills, Northeastern states, and the catchment areas of Himalayan rivers, often causing floods in these regions.

Step-by-Step Solution

1
Identify the meteorological feature described in the stem.
The stem describes a 'monsoon break' caused by the northward displacement of the monsoon trough.
Understanding the position of the monsoon trough is essential for determining spatial rainfall changes.
2
Analyze the atmospheric dynamics of the northward trough displacement.
When the monsoon trough moves north toward the Himalayas, moisture-laden winds encounter the mountainous barrier, resulting in heavy rainfall along the foothills.
Topographic uplift along the Himalayas enhances precipitation locally while rain-bearing depressions fail to form over the plains.
3
Determine the impact on the rest of the country.
With the trough displaced from the central plains, dry spells prevail over central, northern, and western India.
The absence of low-pressure cyclonic disturbances over central India leads to a temporary suppression of widespread rainfall.
