4. Which are the major physiographic divisions of India? Contrast the relief of the Himalayan region with that of the Peninsular plateau
Answer:
The major physiographic divisions of India are
The Himalayan Mountains
The Northern Plains
The Peninsular Plateau
The Indian Desert
The Coastal Plains
The Islands
Contrast the relief of Himalayan region and Peninsular Plateau
Geologically, the Peninsular Plateau constitutes one of the ancient landmasses on the earth’s surface. It was supposed to be one of the most stable land blocks. The Himalayas are the most recent landforms. From the viewpoint of geology, Himalayan mountains form an unstable zone. The whole mountain system of Himalaya represents a very youthful topography with high peaks, deep valleys and fast-flowing rivers. The northern plains are formed of alluvial deposits. The peninsular plateau is composed of igneous and metamorphic rocks with gently rising hills and wide valleys.
