PHYSICAL FEATURES OF INDIA

Brief Overview

India is a land of vast geographical diversity. It encompasses towering mountain ranges, expansive plains, rugged plateaus, long coastlines, and diverse island groups. Understanding these physical features is crucial for studying India's climate, agriculture, and human settlements.

1. Location and Extent

India is located entirely in the Northern and Eastern hemispheres.
* Latitudinal extent: $8^\circ 4' \text{ N}$ to $37^\circ 6' \text{ N}$
* Longitudinal extent: $68^\circ 7' \text{ E}$ to $97^\circ 25' \text{ E}$
* The Tropic of Cancer ($23^\circ 30' \text{ N}$) divides the country into almost two equal halves.
* India has a land boundary of about 15,200 km and a total coastline (including islands) of 7,516.6 km.

Numerical Example:
To find the approximate latitudinal span of India:
$37^\circ - 8^\circ = 29^\circ$. This roughly 30-degree span means India is quite large, which is why there is a significant climate difference between Kashmir in the north and Kanyakumari in the south.

2. Northern Mountains

The Northern Mountains are primarily composed of the Himalayas, which are young fold mountains extending along the northern borders of India. They run in a west-east direction from the Indus to the Brahmaputra.
* The Great Himalayas (Himadri): The northernmost and highest range, with an average elevation of 6,000 meters. Contains Mount Everest and Kanchenjunga.
* The Lesser Himalayas (Himachal): South of Himadri, average altitude 3,700 to 4,500 meters. Famous for hill stations like Shimla, Mussoorie, and Nainital.
* The Shiwaliks: The outermost range, made of unconsolidated sediments, prone to landslides.

Practical Example:
If you travel from New Delhi (Plains) straight North to Mount Everest, you will cross the Shiwaliks first (lowest), then the Himachal (middle), and finally reach the Himadri (highest).

3. North Indian Plains (Plateau area terminology variance)

Note: The syllabus mentions "North Indian Plateau" but conventionally this is referred to as the Northern Plains or the Central Highlands. We will cover the Northern Plains and the Central Highlands (part of the peninsular plateau) here.
The Northern Plains are formed by the interplay of three major river systems: the Indus, the Ganga, and the Brahmaputra. It is formed of highly fertile alluvial soil.
* Bhabar: A narrow belt of pebbles lying parallel to the Shiwaliks where streams disappear.
* Terai: A wet, swampy, and marshy region south of Bhabar where streams re-emerge.
* Bhangar: Older alluvium, forming terraces above the flood plains.
* Khadar: Newer, younger deposits of the flood plains, very fertile and renewed almost every year.

4. Peninsular Plateau

The Peninsular Plateau is a tableland composed of old crystalline, igneous, and metamorphic rocks. It was formed due to the breaking and drifting of the Gondwana land.
* Central Highlands: The part lying north of the Narmada river, covering a major area of the Malwa plateau. The Vindhya range bounds it on the south.
* Deccan Plateau: A triangular landmass lying south of the Narmada river. The Satpura range flanks its broad base in the north. It is bounded by the Western Ghats and Eastern Ghats.
* Western Ghats: Continuous, higher elevation (avg 900-1600m), cause orographic rain. Highest peak: Anamudi.
* Eastern Ghats: Discontinuous, lower elevation (avg 600m), intersected by rivers draining into the Bay of Bengal.

6. Rivers and Lakes

The drainage systems of India are broadly divided into two major groups:

* Peninsular Rivers: Seasonal (flow depends on rainfall). Major rivers: Narmada, Tapi (flow west, form estuaries); Mahanadi, Godavari, Krishna, Kaveri (flow east into Bay of Bengal, form deltas).
* Lakes: Wular lake (largest freshwater lake, tectonic origin in J&K), Chilika lake (largest saltwater lagoon in Odisha), Sambhar lake (salt lake in Rajasthan).

Fun Facts about Physical Features of India!

Growing Mountains: The Himalayas are the youngest mountain range in the world and they are still growing! They rise by about 5 mm every year due to the continuous collision of the Indian and Eurasian tectonic plates.
A Desert of Salt: The Rann of Kutch in Gujarat is one of the largest salt deserts in the world, turning into an endless white landscape during the dry season.
Floating Lake: Loktak Lake in Manipur is the only "floating lake" in the world, famous for its phumdis (floating islands of vegetation) and is home to the endangered Sangai deer.
Majuli Island: Located in the Brahmaputra River in Assam, Majuli is the largest river island in the world!
Oldest Mountains: Unlike the young Himalayas, the Aravalli Range in northwestern India is one of the oldest fold mountain systems in the world, now heavily eroded over millions of years.
