Question

Write a geographical essay on the Peninsular Plateau of India.

Answer 1

The Peninsular Plateau of India is the oldest and most stable landmass of the Indian subcontinent. It is a triangular-shaped tableland, bordered by the Aravalis, Vindhyas, and Satpura ranges in the north, and flanked by the Eastern and Western Ghats on the sides. This plateau forms the core of India's geological structure, having been uplifted during the Pre-Cambrian era (more than 600 million years ago).

1. Extent and Location: The plateau extends roughly from the south of the Indo-Gangetic plains to the southern tip of India at Kanyakumari. It stretches from the Aravalis in the northwest to the Rajmahal Hills in the northeast, covering an area of about 16 lakh square kilometers. Its average elevation ranges from 600 to 900 meters above sea level, and it generally slopes eastwards, which explains why most of the rivers flow into the Bay of Bengal.
2. Divisions of the Plateau: The Peninsular Plateau is divided into three major sections.
   1. The Malwa Plateau (north-western part)
      • Located between the Aravalis and the Vindhyas.
      • Composed mainly of basaltic rocks and drained by rivers like Chambal and Betwa.
      • Known for black soil (regur) in some parts.
   2. The Deccan Plateau (southern part)
      • Lies south of the Satpura range, stretching to the southern tip of India.
      • Bounded by the Western Ghats and Eastern Ghats.
      • Rich in black cotton soil, important for crops like cotton, sugarcane, and millets.
      • Rivers like the Godavari, Krishna, and Cauvery flow here.
   3. The Chotanagpur Plateau (northeastern part)
      • Located in Jharkhand, Chhattisgarh, and Odisha.
      • Known as the “storehouse of minerals” in India: coal, iron, mica, bauxite, etc.
      • Rivers like Damodar and Subarnarekha flow through this region.
3. Economic Significance:
   1. The plateau is rich in minerals such as iron ore, manganese, coal, mica, and bauxite.
   2. It supports agriculture, especially in regions with black soil.
   3. Rivers like the Narmada, Tapi, and Mahanadi provide irrigation and hydropower potential.
   4. The plateau has forests, providing timber and medicinal plants.
4. Unique Features:
   1. Western Ghats: A continuous mountain range with high peaks like Anaimudi and Dodabetta.
   2. Eastern Ghats: Discontinuous hills dissected by rivers like Mahanadi and Godavari.
   3. The plateau has lava plateaus like the Deccan Traps, formed by ancient volcanic activity.
