Overview
The Physical Features of India covers the diverse topographical divisions resulting from tectonic plate movements. Understanding these regions is fundamental for mapping economic zones, climate patterns, and agricultural belts in geography exams.
The Himalayan Mountains
Formed by the convergence of the Indo-Australian and Eurasian plates, the Himalayas are young fold mountains. They act as a climatic barrier and a source for perennial rivers.
- Divided into three parallel ranges: Himadri, Himachal, and Shiwaliks
- Himadri is the northernmost range with an average height of 6,000 meters
- Kanchenjunga and Nanga Parbat are significant peaks
- The Shiwaliks are the outermost, youngest range composed of unconsolidated sediments
- Duns are longitudinal valleys lying between Himachal and Shiwaliks
The Northern Plains
The Northern Plains were formed by the interplay of the Indus, Ganga, and Brahmaputra river systems. These alluvial deposits make the region one of the most agriculturally productive areas in India.
- Bhabar: Narrow belt of pebbles parallel to Shiwalik slopes
- Terai: Wet, swampy region south of Bhabar
- Bangar: Older alluvium deposited above flood levels
- Khadar: Newer, fertile alluvium replenished annually
- Extends over 7 lakh square kilometers
The Peninsular Plateau
This is a tableland composed of the old crystalline, igneous, and metamorphic rocks. It is part of the ancient landmass, Gondwanaland, and is divided into the Central Highlands and the Deccan Plateau.
- Deccan Trap: Region of black soil formed by volcanic origin
- Western Ghats are continuous; Eastern Ghats are discontinuous
- Narmada River divides the plateau into Malwa and Deccan sections
- Aravalli Hills mark the northwestern edge
- Rich in mineral deposits like iron and coal
Exam Tip
Always draw a rough sketch map of India and label the divisions; examiners award significant marks for accurate geographical diagrams.
Common Mistakes
- Confusing the order of Himalayan ranges (North to South)
- Mixing up definitions of Bangar and Khadar alluvial deposits
- Failing to mention the tectonic plate convergence as the cause for Himalayan formation
