Indian Physiography and Major Mountain Ranges

Indian Physiography

• India's diverse topography encompasses mountains, plateaus, plains, and coastal regions.
• The Himalayan mountain range forms the northern boundary, encompassing the Great Himalayas, the Lesser Himalayas, and the Siwalik Hills.
• The Indo-Gangetic Plain, formed by the Indus, Ganges, and Brahmaputra rivers, is a vast fertile area.
• The Deccan Plateau, a large triangular landmass, stretches across central and south India.
• The Western and Eastern Ghats border the coastal plains, influencing rainfall patterns.

Major Mountain Ranges and their Characteristics

• Himalayan Range: A young folded mountain system, geologically active, characterized by high altitude peaks, including Mount Everest.
• Vindhya Range: An older, less rugged range separating the northern and southern plateaus.
• Aravalli Range: The oldest mountain range in India, with a low elevation and reduced relief.
• Western Ghats: A continuous mountain chain, influencing the monsoon patterns and biodiversity hotspot.
• Eastern Ghats: A discontinuous mountain range, with varying elevations and significantly affected by sediment deposition.

River Systems in India

• Indus River System: Originates in the Himalayas, flowing through the western part of the country.
• Ganga River System: Originates in the Himalayas, flowing through the central part of the country, and emptying into the Bay of Bengal.
• Brahmaputra River System: Originates in the Himalayas, merging with the Ganga before emptying into the Bay of Bengal.
• Godavari River: The longest river in peninsular India.
• Krishna River: A major river flowing through southern India and discharging into the Bay of Bengal.
• Narmada and Tapti Rivers: Flow west to the Arabian Sea.
• Characteristics of peninsular rivers: Seasonal flow, monsoon-dependent, typically originate from the Western Ghats, and flow generally eastward.
• Characteristics of Himalayan rivers: Perennial flow, originating from high altitudes, eroding deep valleys.

Coastal Regions

• Western Coast: Characterized by narrow coastal strips, lagoons, and backwaters.
• Eastern Coast: Characterized by broader plains, deltas, and estuaries.
• Coastal plains: Relatively low-lying areas bordering the coast, typically fertile and prone to erosion along the Indian subcontinent.

Plateaus

• Deccan Plateau: Features flat terrain, rich in minerals, and historically crucial in agricultural practices.
• Chota Nagpur Plateau: A plateau region in central India, rich in minerals like iron ore.
• Malwa Plateau: Occupies a significant area in central India and famous for its agricultural production and mineral deposits.

Deserts

• Thar Desert: Located in western India and characterized by arid conditions.
• Deserts influence agriculture and human settlement in India.

Islands

• Lakshadweep Islands: Located in the Arabian Sea.
• Andaman and Nicobar Islands: Located in the Bay of Bengal.
• Impact of Islands: Unique ecosystems and biodiversity, influence maritime activities and coastal processes.

Important Geographical Features

• Indo-Gangetic Plain: Significant agricultural practices and population density.
• Himalayan Region: Critical role in water resources, biodiversity, and climate.
