2. Muga silk is a wild silk variety that is geographically exclusive to Assam and holds a Geographical Indication (GI) tag.

Which of the statements given above is/are correct?

Cevabı ve açıklamayı göster

Cevap: Both 1 and 2

Cevap

Both statement 1 and statement 2 are correct.
Both statements are correct. India produces five commercial types of silk: Mulberry, Tropical Tasar, Temperate Tasar, Eri, and Muga. Mulberry silk is primarily concentrated in South India (Karnataka, Andhra Pradesh, Tamil Nadu), with Karnataka producing the largest share. Muga silk is unique to Assam and holds the GI tag due to its exclusive geographical production zone in the Brahmaputra valley.

Adım Adım Çözüm

1
Evaluate Statement 1 regarding mulberry silk distribution.
Mulberry silk accounts for the majority of silk produced in India, and its cultivation is concentrated in southern Peninsular states, with Karnataka leading production followed by Andhra Pradesh and Tamil Nadu.
Topographical and climatic conditions in Southern India favor year-round sericulture and mulberry plant cultivation.
2
Evaluate Statement 2 regarding Muga silk distribution.
Muga silk, derived from Antheraea assamensis, is golden-yellow silk produced almost exclusively in the Brahmaputra valley of Assam.
The specific ecological host plant requirements (Som and Soalu trees) restrict wild Muga silk production endemic to Assam, earning it a GI tag.
3
Synthesize the statement evaluations to select the correct choice.
Since both statement 1 and statement 2 are accurate, the option stating 'Both 1 and 2' is correct.
Conjoins the valid spatial distribution facts of both Mulberry and Vanya (wild) silks.

The seasonal withdrawal of the South-West monsoon from North-Western India, which typically begins in early September, is primarily driven by which of the following atmospheric changes?

Cevabı ve açıklamayı göster

Cevap: The southward retreat of the Inter-Tropical Convergence Zone (ITCZ) accompanied by the weakening of the intense heat low over North-West India

Cevap

The southward retreat of the Inter-Tropical Convergence Zone (ITCZ) accompanied by the weakening of the intense heat low over North-West India.
Monsoon withdrawal begins when solar insolation over the northern sub-continent decreases in late autumn. This causes the Inter-Tropical Convergence Zone (ITCZ) to migrate southwards. As a result, the intense thermal low over North-West India breaks down, allowing land-to-sea pressure gradients to form and triggering clear skies and retreating wind patterns.

Adım Adım Çözüm

1
Analyze the solar movement and surface pressure conditions in late summer
By September, the Sun's apparent movement shifts southward toward the equator, reducing solar insolation over the Northern Hemisphere.
Solar declination change alters thermal contrast between the Indian landmass and the ocean.
2
Trace the movement of the low-pressure system (ITCZ)
The trough of low pressure (Monsoon Trough/ITCZ) over North-West India weakens and shifts southward.
Without the thermal low driving the pressure gradient, moisture-bearing south-westerly winds lose momentum.
3
Evaluate the wind pattern reversal leading to withdrawal
Clear skies and rising pressure establish north-easterly flow, marking the systematic retreat of the monsoon from Punjab and Rajasthan.
The change in atmospheric driving forces leads to the onset of the retreat phase.

Consider the following statements regarding Black Soil (Regur Soil) in India:

1. It is rich in soil nutrients such as calcium carbonate, magnesium, potash, and lime, but generally poor in nitrogen and phosphorus contents.
2. Due to its high clay content, it develops deep cracks during dry summers, which aids in soil aeration through a process often called 'self-ploughing'.
3. It is predominantly formed by the alluvial deposition of the Ganga and Brahmaputra river systems in northern India.

Which of the statements given above is/are correct?

Cevabı ve açıklamayı göster

Cevap: 1 and 2 only

Cevap

Statements 1 and 2 are correct. Black soil is rich in calcium carbonate, magnesium, potash, and lime, but deficient in nitrogen, phosphorus, and organic matter. High clay content causes it to swell when wet and shrink when dry, forming deep cracks that facilitate self-ploughing. However, it is formed by weathering of Deccan basaltic lava, not alluvial river deposits.
The combination indicating 1 and 2 only is correct because Black Soil contains calcium carbonate, potash, lime, and magnesium, and its clayey nature creates deep cracks upon drying ('self-ploughing'). Statement 3 is false because Black Soil originates from lava rocks of the Deccan Plateau, whereas northern plains consist of alluvial soil.

Adım Adım Çözüm

1
Evaluate Statement 1 regarding chemical composition of Black Soil.
Statement 1 is correct. Black soil (Regur) contains high amounts of lime, iron, magnesium, alumina, and potash, but lacks nitrogen, phosphorus, and humus.
Pedological studies of Deccan trap soils confirm this mineral signature.
2
Evaluate Statement 2 regarding physical characteristics and moisture retention.
Statement 2 is correct. High clay content gives black soil high moisture retention; drying causes reticulate cracking that aerates lower soil horizons ('self-ploughing').
Shrink-swell behavior of montmorillonite clay minerals causes this structural phenomenon.
3
Evaluate Statement 3 regarding geographic origin and distribution.
Statement 3 is incorrect. Black soils are residual soils derived from Deccan trap basalt rocks found across Maharashtra, Madhya Pradesh, Gujarat, and northern Karnataka, whereas alluvial soils dominate northern river plains.
Geological origin of regur soil is parent basaltic rock weathering, not river sediment deposition.

Cevap

Hazira-Vijaipur-Jagdishpur (HVJ) Pipeline matches with First major cross-country natural gas pipeline supplying fertilizer and power plants across western and northern India; Naharkatia-Nunmati-Barauni Pipeline matches with Pioneer inland crude oil pipeline connecting Assam oilfields to eastern refineries in Assam and Bihar; Kudremukh to Mangalore Pipeline matches with Specialized slurry pipeline transporting crushed iron ore from mountain mines to a coastal export port; and Salaya-Koyali-Mathura Pipeline matches with Major crude oil trunk pipeline carrying imported and offshore oil from Gujarat coast to northern inland refineries.
Each pipeline is correctly matched with its specific commodity and route profile: HVJ handles natural gas from western to northern hinterlands; Naharkatia-Barauni handles northeastern crude oil; Kudremukh-Mangalore handles iron ore slurry; and Salaya-Koyali-Mathura handles crude oil imported via the western coast to inland refining hubs.

Adım Adım Çözüm

1
Identify the commodity type and primary function of the HVJ Pipeline
HVJ is India's first major cross-country natural gas network linking Hazira (Gujarat) to industrial consumers in MP and UP.
HVJ stands for Hazira-Vijaipur-Jagdishpur and is operated by GAIL for natural gas distribution.
2
Identify the geographical coverage of the Naharkatia-Nunmati-Barauni Pipeline
It originates in Assam (Naharkatia oilfields) and feeds refineries in Guwahati (Nunmati) and Barauni (Bihar).
It was India's first long-distance crude oil pipeline built in the northeastern sector.
3
Determine the mode and cargo transported by the Kudremukh to Mangalore link
It carries iron ore slurry across the Western Ghats to Mangalore port.
Slurry pipelines reduce transport costs for bulk minerals from inland mines to maritime terminals.
4
Determine the role of the Salaya-Koyali-Mathura pipeline infrastructure
It moves imported and Gulf of Kutch crude oil inland to Koyali, Mathura, and Panipat refineries.
Salaya acts as an offshore/coastal receiving terminal for crude oil destined for northern refineries.
