- India has a diverse physical geography, including mountains, plateaus, plains, deserts, and coastal regions.
- The country is divided into six major physiographic divisions based on topography and geological formations.
๐ Fact: Indiaโs total land area is 3.28 million sq km, making it the 7th largest country in the world.
2. Major Physical Divisions of India
Physiographic Division | Key Features | Example |
---|---|---|

๐ Fact: The Himalayas are still growing due to tectonic activity.
4. The Northern Plains โ The Fertile Lowlands ๐พ
- Formed by the deposition of alluvium from major rivers (Ganga, Indus, Brahmaputra).
- Extends from Punjab to Assam and is the most fertile region in India.
- Divided into three sections:
Section | Region Covered |
---|---|
Punjab Plains | Western India (Punjab, Haryana) |
Ganga Plains | UP, Bihar, West Bengal |
Brahmaputra Plains | Assam, Arunachal Pradesh |
๐ Fact: The Indo-Gangetic Plains are among the most densely populated regions in the world.
5. The Peninsular Plateau โ The Oldest Landform โฐ๏ธ
- Made of igneous and metamorphic rocks, rich in minerals.
- Divided into two main plateaus:
Plateau | Key Features | Example |
---|---|---|
Deccan Plateau | Largest plateau, volcanic origin | Karnataka, Maharashtra |
Chotanagpur Plateau | Rich in minerals (coal, iron) | Jharkhand, West Bengal |
๐ Fact: The Western Ghats and Eastern Ghats are part of the Deccan Plateau.
6. The Indian Desert โ The Thar Desert ๐๏ธ
- Located in Rajasthan, it extends into Gujarat and Pakistan.
- Extreme climate, hot summers and cold winters.
- Key Features:
โ Sand dunes ๐ต
โ Sparse vegetation ๐พ
โ Camel-based economy ๐ซ
๐ Fact: Jaisalmer is called the โGolden Cityโ due to its desert landscape.
7. The Coastal Plains โ The Coastal Lowlands ๐
- India has a coastline of 7,516 km, divided into Western and Eastern Coastal Plains.
Coastal Plain | Location | Major Features |
---|---|---|
Western Coastal Plains | Between the Western Ghats and Arabian Sea | Narrow, backwaters, ports |
Eastern Coastal Plains | Between the Eastern Ghats and Bay of Bengal | Broad, fertile, river deltas |
๐ Fact: Keralaโs backwaters are part of the Western Coastal Plains.
8. The Islands of India โ Andaman & Lakshadweep ๐๏ธ
Island Group | Key Features |
---|---|
Andaman & Nicobar Islands | Volcanic origin, dense forests, indigenous tribes |
Lakshadweep Islands | Coral atolls, lagoons, small area |
๐ Fact: Barren Island in Andaman is Indiaโs only active volcano.
9. Rivers of India โ Lifelines of the Nation ๐
- Two main river systems:
River System | Major Rivers | Flow Direction |
---|---|---|
Himalayan Rivers | Ganga, Yamuna, Brahmaputra | Perennial (flow all year) |
Peninsular Rivers | Godavari, Krishna, Narmada | Seasonal, east/west flow |
๐ Fact: Ganga is the longest river in India (2,525 km).
