Question 819
The Karbi Anglong Plateau, situated in the state of Assam, belongs to which physical division of India?
Answer
Peninsular Plateau
Why?
The correct answer is Peninsular Plateau . Key Points Peninsular Plateau The Karbi Anglong Plateau, located in the state of Assam, is considered an extension of the Peninsular Plateau of India. While Assam is geographically situated in the northeastern part of India, a significant portion of its landmass, including the Karbi Anglong Plateau, shares geological characteristics and evolutionary history with the ancient Peninsular block. The Peninsular Plateau is one of the oldest and most stable landmasses of India, primarily composed of igneous and metamorphic rocks. The Karbi Anglong Plateau exhibits similar rock formations and is believed to have been a part of the Gondwanaland supercontinent, from which the Peninsular Plateau originated. This connection to the Peninsular block distinguishes it from the younger Himalayan mountain ranges and the alluvial plains formed by the river systems originating from the Himalayas. Additional Information Coastal Plain The Coastal Plain of India is a narrow strip of land bordering the Arabian Sea and the Bay of Bengal. It is formed by the deposition of sediments by rivers and marine processes. The Karbi Anglong Plateau, being an elevated inland region of Assam, is geographically and geologically distinct from the coastal plains. The physical characteristics, soil types, and geological history of the coastal plains are different from those of the Karbi Anglong Plateau. Plains of the North The Plains of the North , also known as the Indo-Gangetic Plains, are a vast alluvial plain formed by the depositional work of the Indus, Ganga, and Brahmaputra river systems and their tributaries. These plains are characterized by fertile alluvial soil and a relatively flat topography. The Karbi Anglong Plateau, with its undulating terrain and older rock formations, is clearly separate from the young, depositional plains of North India. While the Brahmaputra River flows through Assam and contributes to its plains, the Karbi Anglong Plateau is an elevated, dissected terrain. Himalayan mountains The Himalayan mountains are a young fold mountain range formed by the collision of the Indian and Eurasian tectonic plates. They are characterized by high peaks, steep slopes, and a different geological composition compared to the Peninsular Plateau. The Karbi Anglong Plateau, although located in the northeastern part of India, predates the formation of the Himalayas and is not part of this mountain range. Its lower elevation and older rock structure clearly differentiate it from the towering and geologically younger Himalayas.
