Correct Answer - Option 2 : ii, iii and iv

The correct answer is ii, iii and iv.

  • The Great Boundary Fault is a major tectonic lineament in northwestern India that runs close to the contact between the Vindhyan sedimentary rocks (ca. 1400-600 Ma) and the pre-Vindhyan rocks.
  • It is a major tectonic lineament in southeastern Rajasthan along the Bundi-Sawaimadhopur hills.
  • Hadauti plateau
    • It includes 9.6% of the area of Rajasthan. 
    • It is bordered by Malwa Plateau on the east, Aravalli range on the west and Marwar plateau on the south-west.
    • On the northwest, it has Ajmer regions of Rajasthan.
    • The Main Boundary Thrust separates Aravali and Hadoti.
  • Hence, statement 1 is not correct.
  • There are four physiographic divisions of Rajasthan-
    • Western Sandy Plain
    • Aravalli Range & Hilly Region
    • Eastern Plain
    • South-East Rajasthan Plateau (Hadoti Plateau)
  • The physical features of Rajasthan form part of the northern great plains and the peninsular plateau of India. 
  • The southern boundary of the plain begins along the edge of the Great Indian Desert in the state of Rajasthan and continues east along the base of the hills of the Central Highlands to the Bay of Bengal. Hence, statement 3 is correct.
  • The Sandy Arid Plain of Rajasthan is divided into-
    • Marusthali
    • Dune Free Tract
  • Bikaner, Jaisalmer, Phalodi & Pokhran districts- Limestone & Sandstone rocks expose (to lay open) here belong to Jurassic & Eocene formations. It is a rocky but dune-free tract.
  • 41.50 percent area of the western sandy plain is a sand dune-free region. Hence, statement 2 is correct.
  • The Aravallis of Northwestern India is one of the oldest fold mountains of the world. It now forms residual mountains with an elevation of 300m. Hence, statement 4 is correct.
