Question 167Question →

Consider the following statements regarding the physiographic and morphotectonic features of the Coastal Plains of India:

1. The Western Coastal Plain is predominantly a submerged coastal margin, which provides favorable natural conditions for the development of natural ports and harbors.
2. The Eastern Coastal Plain is an emergent coastal margin characterized by a broader continental shelf and extensive river deltas.
3. Due to gentle terrain gradients and long courses, rivers flowing across the Western Coastal Plain construct broad alluvial deltas before entering the sea.

Which of the statements given above are correct?

Show answer & explanation

Answer: 1 and 2 only

Answer

Statements 1 and 2 are correct, while statement 3 is incorrect.
The Western Coastal Plain is a submerged coast created by tectonic faulting, which makes it narrow and indented with natural harbor conditions. The Eastern Coastal Plain is an emergent, broad coast characterized by large prograding deltas. West-flowing rivers have steep gradients and short courses across the narrow western belt, forming estuaries instead of deltas, making the option stating '1 and 2 only' the correct choice.

Step-by-Step Solution

1
Evaluate Statement 1 regarding the Western Coastal Plain structure.
Statement 1 is correct. The Western Coastal Plain (except parts of Malabar) is a submerged coast formed by faulting and down-dropping of the Peninsular block during the Arabian Sea opening. Submergence provides natural deep water near the coast, supporting major natural ports like Kandla, Mumbai, JNPT, Marmagao, and Mangalore.
Geological submergence creates indented shorelines and deep coastal waters suitable for ports.
2
Evaluate Statement 2 regarding the Eastern Coastal Plain structure.
Statement 2 is correct. The Eastern Coastal Plain is an emergent coast formed by continental uplift and marine regression combined with continuous river deposition. It is wide and features extensive deltas formed by rivers like Mahanadi, Godavari, Krishna, and Kaveri.
Emergent coasts are characterized by gentle continental slopes and broad depositional plains.
3
Evaluate Statement 3 regarding depositional landforms of west-flowing rivers.
Statement 3 is incorrect. Rivers originating in the Western Ghats flowing west (such as Narmada, Tapi, Mandovi, Sharavati, Periyar) have short, steep courses with high energy. Because the western coast is submerged and steep, these rivers deposit minimal sediment on land and form estuaries rather than broad deltas.
Short steep slopes and submerged coastal margins prevent delta formation, creating estuaries instead.

Show answer & explanation

Answer

Tea pairs with deep acidic well-drained hill slope soil; Cotton pairs with moisture-retaining Vertisols requiring 210 frost-free days; Natural Rubber pairs with hot-humid equatorial climate and lateritic soils; Jute pairs with annually renewed floodplain silt (Khadar).
Each crop is accurately paired with its definitive pedological, thermal, and moisture thresholds: Tea with acidic hill-slope soils, Cotton with Vertisols and 210 frost-free days, Rubber with equatorial high-rainfall lateritic soils, and Jute with deltaic Khadar silt.

Step-by-Step Solution

1
Analyze the pedological and drainage requirements for plantation crops (Tea and Rubber)
Tea requires acidic soils on gentle hill slopes to avoid root rot from stagnant water (150−250 cm150-250\text{ cm} rainfall). Rubber requires hot-humid equatorial conditions (>200 cm>200\text{ cm} rainfall) on well-drained lateritic slopes.
Topography and soil acidity are critical factors differentiating tea plantations from other equatorial tree crops.
2
Evaluate climatic and soil conditions for cash fiber crops (Cotton and Jute)
Cotton needs clayey black Vertisols, moderate rainfall, 210210 frost-free days, and sunny harvest periods. Jute requires heavy rainfall and annually replenished riverine silt (Khadar) in deltaic plains.
Soil texture (Vertisols vs Khadar silt) and sunshine/frost duration dictate the spatial distribution of cotton vs jute.
3
Verify all four matching pairs against standard agro-climatic zones of India
Tea matches gentle acidic hill slopes; Cotton matches Vertisols with 210 frost-free days; Rubber matches hot-humid lateritic belts; Jute matches renewed floodplain Khadar silt.
Ensures full pedagogical consistency across all soil and climate parameters.

The Eastern Dedicated Freight Corridor runs from Sahnewal (Ludhiana) to Dankuni. Kamarajar Port (Ennore) is uniquely structured as a corporatised entity among India's major ports. Statement 4 is false because the Prayagraj-Haldia stretch along the Ganga-Bhagirathi-Hooghly system is designated as National Waterway-1 (NW-1), whereas National Waterway-2 (NW-2) covers the Brahmaputra river from Dhubri to Sadiya.

Step-by-Step Solution

1
Evaluate Statement 1 regarding National Waterway-3
National Waterway-3 (NW-3) extends from Kottapuram to Kollam along the West Coast Canal, including the Champakara and Udyogamandal canals in Kerala (total length 205 km). Statement 1 is correct.
Verify canal and route alignment in Southern India inland navigation.
2
Evaluate Statement 2 regarding the Eastern Dedicated Freight Corridor (EDFC)
The EDFC starts at Sahnewal (Ludhiana, Punjab) and ends at Dankuni (West Bengal), serving heavy freight traffic across northern and eastern India. Statement 2 is correct.
Verify corridor terminals for freight logistics.
3
Evaluate Statement 3 regarding Kamarajar Port
Kamarajar Port Limited (formerly Ennore Port) is India's 12th major port and the only major port incorporated as a company under the Companies Act, 1956. Statement 3 is correct.
Verify corporate governance structure among Indian Major Ports.
4
Evaluate Statement 4 regarding National Waterway-2
National Waterway-1 (NW-1) covers the Ganga-Bhagirathi-Hooghly river stretch from Prayagraj to Haldia (1,620 km). National Waterway-2 (NW-2) covers the Brahmaputra River from Dhubri to Sadiya (891 km). Thus, Statement 4 is incorrect.
Identify numbering and river alignment mismatches across national waterways.

According to Köppen's scheme of climatic classification of India, the extensive region covering the Ganga Plains, eastern Rajasthan, and northern Madhya Pradesh is characterized by a humid subtropical climate with dry winters and hot summers. Which of the following Köppen climate symbols accurately represents this region?

Show answer & explanation

Answer: Cwg

Answer

The correct climate code is Cwg, representing a humid subtropical climate with dry winters found across the Ganga plains.
Köppen classified the climate of the Ganga Plains, eastern Rajasthan, and parts of central India as 'Cwg'. Here, 'C' stands for warm temperate/subtropical climate (coldest month average temperature between -3°C and 18°C), 'w' indicates dry winter season, and 'g' stands for the Ganges type of temperature pattern where the maximum temperature occurs prior to the summer rainy season.

Step-by-Step Solution

1
Identify the geographical region described in the prompt.
The target region encompasses the Ganga Plains, eastern Rajasthan, and northern Madhya Pradesh.
Köppen mapped specific empirical symbols to distinct temperature and rainfall regimes across India.
2
Match the seasonal temperature and precipitation features to Köppen's classification system.
The region experiences hot summers, rainy monsoon periods, and dry winters, fitting the 'Cwg' designation.
In Köppen's nomenclature, 'C' denotes warm temperate/humid subtropical, 'w' indicates dry winters, and 'g' signifies the Ganges type temperature profile.
