If there were no Himalayan ranges, what would have been the most likely geographical impact on India? 1. Much of the country would experience the cold waves from Siberia. 2. Indo-gangetic plain would be devoid of such extensive alluvial soils. 3. The pattern of monsoon would be different from what it is at present. Which of the statements given above is/are correct?

1. The question asks about the likely geographical impact on India if the Himalayan ranges did not exist. 2. Statement 1: The Himalayas act as a massive barrier, preventing the extremely cold waves from Siberia and Central Asia from entering the Indian subcontinent during winter. Without them, much of the country, especially North India, would experience significantly colder winters. This statement is correct. 3. Statement 2: The Indo-gangetic plain owes its existence and fertility to the vast amounts of silt (alluvial soils) deposited by the Himalayan rivers (Indus, Ganga, Brahmaputra, and their tributaries) over millennia. These rivers originate in or are fed by the Himalayas. Without the Himalayas, these rivers wouldn't exist in their current form, and the plains would be devoid of such extensive alluvial soils. This statement is correct. 4. Statement 3: The Himalayas play a crucial role in India's climate, particularly the monsoon. They intercept the moisture-laden summer monsoon winds, forcing them to rise and causing heavy rainfall across the plains. They also influence the path of winter weather systems. Without the Himalayas, the pattern of monsoon would be drastically different, likely much weaker and penetrating less inland. This statement is correct. 5. Since all three statements describe likely impacts, the correct answer is (D) 1, 2 and 3.
