Question

Explain the features of the Northern Mountains and their impact on India’s climate.

Hint:

The Northern Mountains, especially the Himalayas, play a vital role in {protecting India from cold winds, influencing monsoon rainfall, and supplying water through major river systems}. They are one of the most important physical features shaping India's climate.

Answer 1

Concept: The Northern Mountains of India mainly refer to the Himalayan mountain system. They form a vast and continuous mountain range in the northern part of the Indian subcontinent. These mountains play an important role in shaping the physical geography and climate of India. Features of the Northern Mountains: 1. Young Fold Mountains: The Himalayas are young fold mountains formed due to the collision of the Indian Plate with the Eurasian Plate. Because of their relatively recent geological formation, they have high peaks, steep slopes, and deep valleys. 2. Three Parallel Ranges: The Himalayan mountain system consists of three main parallel ranges:

• The Great Himalayas (Himadri): The highest range with many of the world's highest peaks and permanent snow cover.
• The Lesser Himalayas (Himachal): Located south of the Himadri, consisting of rugged mountains and deep valleys.
• The Outer Himalayas (Shiwalik): The southernmost range made of loose sediments and relatively lower hills.

3. High Peaks and Glaciers: The Northern Mountains contain many high peaks and large glaciers. These glaciers are the source of several major rivers such as the Ganga, Yamuna, and Brahmaputra. 4. Natural Barrier: The Himalayan ranges form a natural barrier between the Indian subcontinent and Central Asia, protecting India from cold winds and invasions from the north. Impact of the Northern Mountains on India’s Climate: 1. Blocking Cold Winds: The Himalayas prevent the cold, dry winds from Central Asia from entering the Indian subcontinent. This helps maintain relatively warmer conditions in northern India during winter. 2. Influencing Monsoon Rainfall: The Himalayas play a crucial role in the Indian monsoon system. When the moisture-laden southwest monsoon winds reach the Himalayas, they are forced to rise, leading to heavy rainfall in the northern and northeastern parts of India. 3. Formation of River Systems: The glaciers in the Northern Mountains feed perennial rivers such as the Indus, Ganga, and Brahmaputra, which provide water for agriculture, drinking, and hydroelectric power. 4. Creating Climatic Diversity: The varying altitudes and landscapes of the Himalayas create different climatic zones, ranging from tropical conditions at the foothills to extremely cold conditions at higher altitudes.
