Question Discussion & Solution

The correct answer is A - i, B - ii, C - iii, D - iv.

Key Points

•  Aridisols soil
  • These are CaCO₃-containing soils of arid regions that exhibit subsurface horizon development.
  • They are characterized by being dry most of the year and limited leaching.
  • They contain subsurface horizons in which clays, calcium carbonate, silica, salts, and/or gypsum have accumulated.
• Inceptisols soil
  • It exhibits minimal horizon development.
  • They are more developed than Entisols, but still lack the features that are characteristic of other soil orders.
  • A sizable percentage of Inceptisols are found in mountainous areas and are used for forestry, recreation, and watershed.
  • They occur in cool to very warm and humid to subhumid climates, from the arctic to the tropics.
  • They are found in Semi-arid and humid regions.
• Alfisols soil
  • They are moderately leached soils that have relatively high native fertility.
  • These soils have mainly formed under forest and have a subsurface horizon in which clays have accumulated.
  • They are primarily found in temperate humid and subhumid regions of the world.
• Vertisols
  • They are clayey soils that have deep, wide cracks for some time during the year.
  • They shrink as they dry and swell as they become moist.
  • The natural vegetation is predominantly grass, savanna, open forest, or desert shrub.
  • They are found in Humid and super-humid regions.

Soil distribution:

The correct answer is ​I-c, II-a, III-d, IV-b.

Additional Information

•  Haduti

  • The southern-eastern part of Rajasthan is known as the plateau of Hadoti.
  • It is an extensio
  • n of the plateau of Malwa and its expansion is in Kota, Bundi, Jhalawar, and Baran districts.

  • Here Chambal river and its major tributaries Kalisindh, Parvan, and Parvati rivers flow.

• Bhomat

  • ​The tribal area of Udaipur, the hilly area of Dungarpur, and the Eastern Sirohi area are called Bhomat.
  • Bhomat is a hilly region of Rajasthan.
  • This region is a Bhil multiplicity zone.
  • The Bhomat region was the refuge of the Mewar rulers during the Mughal period. 

  • The primary rivers are Som, Vakal, and Sabarmati.

• Vagad

  • The area of ​​Banswara, Pratapgarh, Dungarpur is called Vagad in the local language.
  • This is the flow area of ​​the Mahi River.

  • This area is uneven and there are small hills everywhere.

• Abrud

  •  It is the southern part of Aravalli.
  • It is located in the Mount Abu region in the Sirohi district.
  • Guru Shikhar Peak is the highest mountain peak in Rajasthan. 

The peninsular rivers :

• The peninsular rivers are the rivers that originate from the peninsular plateaus and small hills of India.
• These rivers are seasonal or non-perennial as they receive water only from the rains and thus cannot maintain water flow throughout the year.
• Some of the famous peninsular rivers include Kaveri, Narmada, Tapi, Krishna, Mahanadi, and the Godavari.
• Few of them are east flowing and drains into the Bay of Bengal, i.e. Mahanadi, Godavari, Krishna, Kaveri, etc.
• The others are west-flowing rivers, i.e. Narmada, Tapi, Luni, Mahi, etc.

Narmada: 

• It is located mainly in Madhya Pradesh.
• The Narmada River is also known as the Rewa River.
• The River is originated from the Maikala range near Amarkantak.
• It is a West flowing river and flows from the rift valley of Vindhyan and Satpura ranges. 
• The River flows through Gujarat, Chhattisgarh Madhya Pradesh, and Maharashtra.
• The tributaries of the Narmada River are Kolar River, Shakkar River, Dudhi River, Tawa River, and Hiran River.
• Major Hydro Power projects in this river are Maheshwar Dam, Sardar Sarovar Dam, and Indira Gandhi Sagar Dam.

Hence, it is clear from the above discussion that the river Narmada is the longest of all. 

So, option 1 is the correct answer.

The correct answer is In the districts of Ganganagar & Hanumangarh.

Key Points

• 'Ghagghar ka Maidan' is situated in the districts of Ganganagar and Hanumangarh.
• The Ghaggar-Hakra River is an intermittent river in India and Pakistan that flows only during the monsoon season.
  • The river is known as Ghaggar in India, before the Ottu barrage, and as the Hakra in Pakistan, downstream of the barrage, ending in the Thar desert.
• In pre-Harappan times the Hakra was a tributary of the Sutlej.
  • It is still connected to this paleochannel of the Sutlej, and possibly the Yamuna, which ended in the Nara River, presently a delta channel of the Indus River joining the sea via Sir Creek.

Additional Information

• The Ghaggar is an intermittent river in India, flowing during the monsoon rains.
  • It originates in the village of Dagshai in the Shivalik Hills of Himachal Pradesh at an elevation of 1,927 meters (6,322 ft) above mean sea level and flows through Punjab and Haryana states into Rajasthan just southwest of Sirsa, Haryana, and by the side of Talwara Lake in Rajasthan.
  • Dammed at Ottu barrage near Sirsa, Ghaggar feeds two irrigation canals that extend into Rajasthan.
• The main tributaries of the Ghaggar are the Kaushalya river, Markanda, Sarsuti, Tangri and Chautang.
• The Kaushalya river is a tributary of Ghaggar river on the left side of Ghaggar-Hakra,
• It flows in the Panchkula district of Haryana state of India and confluences with Ghaggar river near Pinjore just downstream of Kaushalya Dam.

The correct answer is Aravali hills.

Key Points

• Aravalli:
  • The Aravallis of Northwestern India is one of the oldest fold mountains of the world, now form residual mountains with an elevation of 300 m to 900 m.
  • They stretch for a distance of 800 km from Himmatnagar in Gujarat to Delhi, spanning Haryana, Rajasthan, Gujarat, and Delhi, the 692 kilometers.
  • The mountains are divided into two, main ranges - the Sambhar Sirohi Range and the Sambhar Khetri Range in Rajasthan, where their extension is about 560 km.
  • The hidden limb of the Aravallis that extends from Delhi to Haridwar creates a divide between the drainage of rivers of the Ganga and the Indus.
  • The Aravallis date back to millions of years when a pre-Indian sub-continent collided with the mainland Eurasian Plate.
  • Carbon dating has shown that copper and other metals mined in the ranges date back to at least the 5th century BC.
  • In fold mountains, rocks are formed primarily of the folded crust when two convergent plates move towards each other by the process called orogenic movement.
