Explanation: The Himalayan mountain system is a complex and vast range that stretches across several countries in South Asia, including India, Nepal, Bhutan, and Pakistan. The Himalayas are divided into three parallel ranges, each with distinct characteristics and geographical positions. Understanding the sequence of these ranges is essential for comprehending the overall structure of the Himalayas.
The three ranges, from south to north, are:
1. **Shiwalik Range (Outer Himalayas)**: This is the southernmost range of the Himalayas. It is a narrow belt of mountains that runs parallel to the main Himalayan range. The Shiwalik range is composed of sedimentary rocks and is characterized by its relatively low elevation compared to the other ranges. It is also known for its fertile soil and is an important agricultural region.
2. **Himachal Range (Lesser Himalayas)**: This range lies between the Shiwalik and the Himadri ranges. It is also known as the Middle Himalayas. The Himachal range is composed of a variety of rock types, including sedimentary, metamorphic, and igneous rocks. It is characterized by its moderate elevation and is home to several important mountain passes and valleys.
3. **Himadri Range (Greater Himalayas)**: This is the northernmost and highest range of the Himalayas. It is also known as the Inner Himalayas or the Great Himalayas. The Himadri range is composed of the oldest and hardest rocks, primarily granite and gneiss. It includes some of the highest peaks in the world, such as Mount Everest, K2, and Kangchenjunga.
The sequence of these ranges from south to north is crucial for understanding the geographical layout of the Himalayas. The Shiwalik range is the southernmost, followed by the Himachal range, and the Himadri range is the northernmost. This sequence is important for various geographical and environmental studies, as well as for understanding the geological history of the region.
In summary, the correct sequence of the Himalayan ranges from south to north is Shiwalik, Himachal, and Himadri. This sequence is based on the geographical positions and characteristics of each range, and it is essential for comprehending the overall structure and layout of the Himalayan mountain system.
