Zorluk: OrtaPhysiography and Relief Features of India

With reference to the relief and structural physiography of the Peninsular Plateau of India, which of the following statements correctly describes the arrangement and structural features of the Vindhya and Satpura mountain ranges?

  1. The Narmada River flows westward through a linear rift valley formed by block faulting, situated between the Vindhya Range to its north and the Satpura Range to its south.Cevap
  2. B
    The Tapi River flows through a rift valley situated directly between the Vindhya Range and the Aravalli Range.
  3. C
    The Satpura Range lies immediately to the north of the Vindhya Range, forming the northern structural boundary of the Malwa Plateau.
  4. D
    The structural rift valley between the Vindhya and Satpura ranges was created by tectonic subsidences in the laterite soil belt of the Eastern Ghats.

Cevap

The statement accurately describing the relief is that the Narmada River flows westward through a linear rift valley formed by block faulting, situated between the Vindhya Range to its north and the Satpura Range to its south.
The Central Highlands of Peninsular India are characterized by block faulting. The Vindhya Range to the north and the Satpura Range to the south act as horst structures enclosing the Narmada graben (rift valley), through which the Narmada River flows westward into the Arabian Sea.

Adım Adım Çözüm

1
Identify the geographical relative orientation of the Vindhya and Satpura mountain ranges in Central India.
The Vindhya Range lies to the north of the Satpura Range.
Establishing north-to-south spatial sequence is necessary to evaluate physiographic relations.
2
Examine the linear drainage and structural trough lying between these two ranges.
The Narmada River occupies the fault-trough (graben) formed by parallel block faulting between the Vindhyas (north scarp) and Satpuras (south horst).
Relief features in Central India are largely governed by tectonic rift systems.
3
Evaluate the distractors against known spatial orientations and geological mechanisms.
The Tapi flows south of the Satpuras, Satpura is south (not north) of Vindhya, and the rift is in the Central Highlands (not Eastern Ghats).
Eliminating false directional and regional mismatches leads strictly to the correct statement.
