The Deccan Plateau, Central Highlands and North-Eastern Plateau

The Deccan Plateau: 

• The Western Ghats are to the west, the Eastern Ghats are to the east, and the Satpura, Maikal range, and Mahadeo hills are to the north
• Locals refer to the Western Ghats by a variety of names: Maharashtra’s Sahyadri
• The Nilgiri Mountains are located in the regions of Karnataka and Tamil Nadu
• Anaimalai and Cardamom hills, on the other hand, are present in Kerala
• The Western Ghats are higher in elevation and more continuous than the Eastern Ghats
• With the height increasing from north to south, the average elevation is around 1,500 meters
• On the Nilgiri hills, Anaimudi (2,695 m) is the highest peak in the peninsular region, followed by Dodabetta (2,637 m)
• The Mahanadi, the Godavari, the Krishna, the Kaveri, and other rivers erode the Eastern Ghats, consisting of discontinuous and low hills
• The Nilgiri hills are where the Eastern and Western Ghats meet

The Central Highlands:

• The Aravali range encircles them on the west
• On the south, the Satpura range is formed by a succession of scarped plateaus with elevations ranging from 600 to 900 meters above mean sea level
• It rises to a height of 700-1,000 metres above sea level and slopes north and northeast
• The Deccan plateau‘s northernmost boundary is formed by this
• It’s a classic example of relict mountains, which are densely forested and create irregular ranges
• The existence of metamorphic rocks such as marble, slate, gneiss, and other metamorphic rocks confirms that the western section of this peninsular part has undergone metamorphic processes in its geological history
• The Central Highlands are located between 700 and 1,000 meters above sea level
• It has a northern and northeastern inclination
• The Vindhyan and Kaimur ranges are the source of the majority of the Yamuna’s tributaries
• Banas is the only notable tributary of the Chambal River, which flows westward from the Aravalli
• An eastern extension of the Central Highland is formed by the Rajmahal hills, to the south of which lies a large reserve of mineral resources in the Chotanagpur plateau

The North-Eastern Plateau:

• It is a peninsular plateau expansion
• It is thought that during the Himalayan origin, a massive fault was developed between the Rajmahal hills and the Meghalaya plateau due to the stress exerted by the Indian plate’s north-eastward migration
• The Garo Hills, Khasi Hills, and Jaintia Hills are the three regions that make up the Meghalaya plateau. An extension of this can be observed in Assam’s Karbi Anglong hills
• Mineral resources like coal, iron ore, sillimanite, limestone, and uranium abound in the Meghalaya plateau
• The southwest monsoon brings the most rain to this region
• As a result, the Meghalaya plateau’s surface is heavily degraded
• Cherrapunji has a barren rocky surface that is free of any kind of permanent vegetation

Conclusion

The Deccan Plateau is bounded on the west by the Western Ghats, on the east by the Eastern Ghats, and on the north by the Satpura, Maikal range, and Mahadeo hills. Local names for the Western Ghats include Sahyadri in Maharashtra, Nilgiri hills in Karnataka and Tamil Nadu, and Anaimalai and Cardamom hills in Kerala.The central highlands are an example of relict mountains, which are densely forested and form discontinuous ranges. The Northeastern Plateau extends from the main Peninsular plateau.
