    Study Notes

    Key Physical Features of India

    • India is a vast country located entirely in the Northern Hemisphere
    • The Indian landmass extends between latitudes 8°4′ N and 37°6′ N, and longitudes 68°7′ E and 97°25′ E
    • India's total area accounts for about 2.4% of the total geographical area of the world
    • The country is divided into two almost equal halves by the Tropic of Cancer passing through the middle
    • India's landmass can be divided into six major physiographic divisions:

    The Himalayan Mountains

    • The youngest and one of the most rugged mountain ranges in the world
    • Stretches over a distance of about 2,500 km
    • Consists of three parallel ranges - the Great or Inner Himalayas, the Lesser Himalayas, and the Outer Himalayas or the Shivaliks
    • The Great Himalayas have the highest peaks with an average height of 6,000 m

    The Northern Plains

    • Formed by the deposition of sediments brought down by the rivers flowing from the Himalayas
    • Extremely flat and fertile region, ideal for agriculture
    • Covers an area of about 7 lakh sq km

    The Peninsular Plateau

    • One of the most ancient land masses on the earth's surface
    • Lies to the south of the Indo-Gangetic Plain
    • Gently slopes from west to east

    The Indian Desert

    • Comprises the western part of the country
    • Characterized by sand dunes, salt lakes, and sparse vegetation

    The Coastal Plains

    • Located along the western and eastern coasts of the country
    • Western Coastal Plain is narrow while the Eastern Coastal Plain is broad

    The Islands

    • The Lakshadweep Islands in the Arabian Sea and the Andaman and Nicobar Islands in the Bay of Bengal

    Contrasts in the Landforms

    • The highest point in India is the K2 peak in the Karakoram range at 8,611 m

    • The lowest point is the Kuttanad region in Kerala which is 2 m below sea level### Geography of the Indian Subcontinent

    • The Indian subcontinent is a vast and diverse land mass, comprising the countries of India, Pakistan, Bangladesh, Nepal, Bhutan, and Sri Lanka

    • The Himalayan mountain range forms the northern boundary of the Indian subcontinent

    • The Himalayan range is divided into three main sections:

      • The Greater Himalayas
      • The Lesser Himalayas (also known as the Himachal or Kumaon Himalayas)
      • The Outer Himalayas (also called the Shivalik or Lower Himalayas)
    • The Greater Himalayas are the highest, with peaks exceeding 8,000 meters

    • The Himalayas were formed by the collision of the Indian and Eurasian tectonic plates, making them one of the youngest and most geologically active mountain ranges

    • The Himalayas are composed of highly compressed and altered rocks, with glaciers and perennial snow cover

    The Northern Plains

    • The Northern Plains are formed by the alluvial deposits of the Indus, Ganga, and Brahmaputra river systems
    • These plains stretch from the Arabian Sea to the Bay of Bengal, covering parts of Pakistan, India, and Bangladesh
    • The Northern Plains are broadly divided into:
      • The Upper Gangetic Plain in the north
      • The Lower Gangetic Plain in the south
    • The rivers flowing through the plains disappear into the Bhabhar belt and re-emerge in the Terai region
    • This region is densely populated and agriculturally very productive due to the fertile alluvial soil and favorable climate

    The Peninsular Plateau

    • The Peninsular Plateau is an ancient, geologically stable landmass composed of igneous and metamorphic rocks
    • It is bordered by the Western Ghats on the west and the Eastern Ghats on the east
    • The Central Highlands and the Deccan Plateau are the two major physiographic divisions of the Peninsular Plateau
    • The Deccan Plateau slopes gently from west to east and is marked by broad and shallow valleys
    • The Western Ghats are higher than the Eastern Ghats, with their average elevation being 900-1,600 meters compared to 600-900 meters for the Eastern Ghats

    Coastal Regions and Islands

    • India has a long coastline along the Arabian Sea, the Bay of Bengal, and the Indian Ocean
    • The western coast is called the Western Coastal Plains, while the eastern coast is known as the Eastern Coastal Plains
    • Major coastal features include the Rann of Kutch, the Lakshadweep Islands, and the Andaman and Nicobar Islands
    • The Lakshadweep Islands are a group of small coral islands located off the south-western coast of India
    • The Andaman and Nicobar Islands are an elongated group of islands located in the Bay of BengalI apologize, but the provided text appears to be a jumbled collection of symbols, emojis, and special characters. It does not form a coherent text that can be understood or summarized.
