1. PHYSICAL FEATURES OF INDIA
2. Introduction India is a vast country with varied landforms. Our country has practically all major physical features of the Earth i. e. Mountains, Plains, Deserts, Plateaus and Islands. India is a large landmass formed during different geological periods which has influenced her relief its present form. The movement of the plates results in building up of stresses within the plates and the continental rocks above, leading to folding, faulting and volcanic activity.
3. CLASSIFICATION OF PLATE MOVEMENTS Plate movements are classified into three types. They are; Convergent Boundary While some plates come towards each other and form convergent boundary. Divergent Boundary some plates move away from each other and form divergent boundary. Transform Boundary In the event of two plates coming together they may either collide and crumble, or one may slide under the other. At times, they may also move horizontally past each other and form transform boundary.
4. Plate Boundaries
5. PLATE BOUNDARIES The oldest landmass, (the Peninsula part), was a part of the Gondwana land. The Gondwana land included India, Australia, South Africa and South America as one single land mass. The convectional currents split the crust into a number of pieces, thus leading to the drifting of the Indo- Australian plate after being separated from the Gondwana land, towards north. The northward drift resulted in the collision of the plate with the much larger Eurasian Plate. Due to this collision, the sedimentary rocks which were accumulated in the geosyncline known as the Tethys were folded to form the mountain system of western Asia and Himalaya.
6. Major Physiographic Divisions
7. Major Physiographic Divisions The Physical features of India can be grouped under the following physiographic divisions i. The Himalayan Mountains. ii. The Northern Plains iii. The Peninsular Plateau iv. The Indian Desert v. The Coastal Plains vi. The Islands
8. HIMALAYAN MOUNTAINS The Himalayan Mountains ranges contain several high peaks. Mount Everest is the highest peak in the world. The Himalayan Mountains stretch in a long curve from Jammu and Kashmir in the west to Arunanchal Pradesh in the east. Their length is about 2000 kilometres and width between 230 and 400 kilometers. The Himalayas act as a natural barrier to the North. These mountain ranges run in a west-east direction from the Indus to the Brahmaputra. The Himalaya consists of three parallel ranges in its longitudinal extent. A number of valleys lie between these ranges. The northern most range is known as the Greater or Inner Himalayas or the ‘Himadri’.
9. Some Highest Peaks of the Himalayas
10. THE NORTHERN PLAINS The Northern plain has been formed by the interplay of the three major river systems, namely- the Indus, the Ganga, the Brahmaputra along with their tributaries. This plain is formed of alluvial soil. The deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years, formed this fertile plain. It spreads over an area of 7 lakh sq. km. The plain being about 2400 km long and 240 to 320 km broad, is a densely populated physiographic division. The rivers in their lower course split into numerous channels due to the deposition of silt. These channels are known as distributaries.
