Explanations:The Himalayan mountain range is a significant geographical feature that spans across several countries in Asia, including India, Nepal, Bhutan, and parts of China. The width of the Himalayas varies significantly from west to east, reflecting the complex geological processes that have shaped this mountain range over millions of years.
The Himalayas are widest in the western part, particularly in Kashmir, where the width is approximately 400 kilometers. This region is characterized by a broad and expansive mountain range, with numerous peaks and valleys. As the Himalayas extend towards the east, the width gradually decreases, reaching about 150 kilometers in Arunachal Pradesh, which is located in the easternmost part of India.
The variation in width is due to several factors, including the tectonic movements that have occurred over millions of years. The Himalayas were formed by the collision of the Indian and Eurasian tectonic plates, which pushed up the land and created the mountain range. The western part of the Himalayas, where the collision was more intense, resulted in a broader and more expansive range. In contrast, the eastern part of the Himalayas experienced less intense tectonic activity, leading to a narrower range.
Understanding the width variation of the Himalayas is important for geographical studies and for comprehending the geological processes that have shaped this region. The correct answer to the question is Option C, which states that the width of the Himalayas varies from 400 km in Kashmir to 150 km in Arunachal Pradesh. This reflects the actual geographical spread and the geological processes that have influenced the formation of the Himalayan mountain range.
