Physical Features of India

India, a land of diverse landscapes, is adorned with a multitude of physical features that add to its unique geographical identity. Spanning over a vast area, the country showcases varied topographies, from the snow-capped Himalayas in the north to the sun-bathed coastal plains in the south. The physical features of India can be broadly categorized into the Himalayan mountains, the Northern Plains, the Indian Desert, the Peninsular Plateau, the Coastal Plains, and the Islands.

The Himalayas, forming the northern boundary, are not just mountains but a complex of ranges and sub-ranges, profoundly influencing the climate and culture of the country. The Northern Plains, fed by perennial rivers like the Ganges, Brahmaputra, and Indus, are the granaries of India, known for their fertile lands. The Indian Desert, primarily the Thar Desert, adds to the arid landscape in the west.

The Peninsular Plateau, heart of India’s mineral wealth, is a region of stable landmass characterized by rolling hills and river valleys. The Coastal Plains, running parallel to the Arabian Sea and the Bay of Bengal, feature beautiful beaches and fertile deltas. These islands, including the Andaman & Nicobar Islands and Lakshadweep, offer a diverse ecosystem unique from the mainland.

Formation of the Land Forms

The formation of India's landforms is a tale of geological evolution spanning millions of years. It's a story that begins with the breaking of the supercontinent Gondwana and the subsequent drift of the Indian tectonic plate. This drift led to the collision of the Indian plate with the Eurasian plate, giving birth to the Himalayas. The Himalayas, still rising, are a testament to this ongoing tectonic activity.

The Northern Plains were formed by the sedimentation brought by the rivers originating in the Himalayas. The Peninsular Plateau, one of the oldest and most stable landforms, is a result of volcanic eruptions and gradual erosion over time.

The Indian Desert, or the Thar Desert, is believed to have formed due to wind erosion, whereas the Coastal Plains are a result of the gradual recession of the sea, leaving behind depositional features like deltas. The islands, particularly the Andaman and Nicobar Islands, are volcanic in origin, while Lakshadweep is a group of coral islands.

Major Physiographical Divisions of India

India's physiography is divided into major divisions, each with its own unique characteristics and significance. The Himalayan Mountains, a young and dynamic range, are crucial for their biodiversity and as a source of major rivers.

The Northern Plains, formed by the alluvial deposits of the Indus, Ganges, and Brahmaputra rivers, are known for their fertile soil and dense population. The Indian Desert, primarily the Thar Desert, offers a stark landscape of sand dunes and sparse vegetation. The Peninsular Plateau, heart of India's mineral wealth, is a tableland composed of the ancient Gondwana land.

This plateau is flanked by the Eastern and Western Ghats, which are crucial for their biodiversity and rainfall patterns. The Coastal Plains, comprising the Eastern and Western coastal plains, are known for their fertile soil, fishing grounds, and ports. Lastly, the Islands, including the Andaman & Nicobar and Lakshadweep, are renowned for their diverse flora and fauna and strategic importance.

Differences between the Western Ghats and Eastern Ghats Class 9 NCERT

The Western Ghats and the Eastern Ghats, two of India's prominent mountain ranges, have distinct characteristics. The Western Ghats, also known as the Sahyadri, run parallel to India's western coast and are a UNESCO World Heritage Site. They are known for their rich biodiversity and are one of the world's eight 'hottest hotspots' of biological diversity. The Ghats intercept the monsoon winds, contributing to high rainfall in the region, supporting unique ecosystems like tropical rainforests. The Western Ghats are relatively higher, more continuous, and feature major peaks like Anamudi and Doddabetta.

In contrast, the Eastern Ghats run parallel to the eastern coast of India and are more eroded and dissected by rivers. They receive less rainfall and are, therefore, drier than their western counterparts. The Eastern Ghats are known for their mineral resources and are home to a wide variety of flora and fauna, but less extensive compared to the Western Ghats. The Eastern Ghats are lower in elevation, and their hill ranges are interrupted and cut through by four major rivers: Godavari, Mahanadi, Krishna, and Kaveri. The differences in climate, biodiversity, and geology between the Western and Eastern Ghats are significant, influencing the culture, agriculture, and lifestyle of the regions they encompass.
