Geography Optional – Paper II (India)
Page–3 : Peninsular Plateau
Previous Year Questions with Model Answers
Q1. Examine the geological evolution of the Peninsular Plateau of India.
The Peninsular Plateau is one of the oldest landmasses of India, composed mainly of Precambrian crystalline rocks. It represents a stable continental block formed through multiple cycles of uplift, denudation and volcanic activity.
The Deccan Trap volcanism during the late Cretaceous period played a significant role in shaping the western part of the plateau. Thus, the plateau reflects long-term tectonic stability combined with episodic volcanic events.
Q2. Discuss the major physiographic divisions of the Peninsular Plateau.
The Peninsular Plateau is divided into the Central Highlands and the Deccan Plateau. The Central Highlands include the Malwa Plateau, Bundelkhand and Chotanagpur regions.
The Deccan Plateau is bordered by the Western and Eastern Ghats and is drained by major rivers such as Godavari, Krishna and Kaveri. These divisions show distinct geological and geomorphological features.
Q3. Explain the role of rivers in shaping the Peninsular Plateau.
Rivers of the Peninsular Plateau are mostly seasonal and follow antecedent and superimposed courses. They have created wide valleys, waterfalls and escarpments, especially along the Western Ghats.
Fluvial erosion has played a dominant role in the dissection of the plateau, influencing settlement patterns, agriculture and water resource development.
