India is divided into six physiographic divisions on basis of the varied physiographic features: units as follows: Northern and North-eastern Mountain; Northern Plain; Peninsular Plateau; Indian Desert; Coastal Plains; and Islands.

Physical Regions of India:
India can be divided into several major physical regions based on its topography and geology. These regions have distinct features and play a crucial role in shaping the country's landscape and climate.

The Northern Mountains:
- The Northern Mountains consist of the Himalayas, the highest mountain range in the world.
- It spans across several states in northern India and acts as a natural barrier to the cold winds from Central Asia.
- The Himalayas are known for their snow-capped peaks, glaciers, and high-altitude valleys.

The Indo-Gangetic Plain:
- The Indo-Gangetic Plain is a vast stretch of fertile land formed by the rivers Ganges, Yamuna, and Brahmaputra.
- It is one of the most densely populated regions in the world and is known for its agriculture and irrigation systems.
- The plain is characterized by alluvial soil and is a major food-producing region in India.

The Peninsular Plateau:
- The Peninsular Plateau is a large plateau region in southern India, bordered by the Western and Eastern Ghats.
- It is made up of ancient rocks and is rich in minerals like iron ore, coal, and limestone.
- The Deccan Plateau is a part of the Peninsular Plateau and is known for its rugged terrain and plateau features.

The Coastal Plains:
- India has two main coastal plains - the Western Coastal Plain along the Arabian Sea and the Eastern Coastal Plain along the Bay of Bengal.
- These plains are characterized by sandy beaches, estuaries, and backwaters.
- The coastal plains are important for trade, fishing, and tourism in India.

The Thar Desert:
- The Thar Desert is a large arid region located in the northwestern part of India, near the border with Pakistan.
- It is known for its extreme temperatures, sand dunes, and sparse vegetation.
- The Thar Desert is an important ecosystem and supports unique flora and fauna adapted to desert conditions.
