Explanation: The Himalayas, the world's highest mountain range, are divided into three main parallel ranges: the Outer Himalayas, the Middle Himalayas, and the Inner Himalayas. Each of these ranges has distinct characteristics and geographical features.
The Outer Himalayas, also known as the Shivalik, are the southernmost range of the Himalayas. They are characterized by their low, discontinuous ranges and hills, which are composed primarily of sedimentary rocks. The Shivalik range extends from the Indus River in the west to the Brahmaputra River in the east, covering parts of India, Pakistan, and Nepal. The Shivalik is often covered with dense forests and is an important ecological region.
The Middle Himalayas, which lie between the Outer and Inner Himalayas, include several well-known ranges such as the Pir Panjal and the Dhauladhar. These ranges are higher and more rugged than the Shivalik and are composed of both sedimentary and metamorphic rocks. The Middle Himalayas are known for their scenic beauty, high peaks, and passes, such as the Pir Panjal range, which includes the famous Rohtang Pass.
The Inner Himalayas, also known as the Great Himalayan Range, are the northernmost and highest range of the Himalayas. They include the Zanskar range and other high peaks such as Mount Everest. The Inner Himalayas are composed of metamorphic and igneous rocks and are characterized by their extremely high altitudes and challenging terrain.
Understanding the geographical position and characteristics of each range is crucial for comprehending the overall structure and features of the Himalayas. The Shivalik, as the Outer Himalayas, plays a significant role in the ecological and geographical landscape of the region, serving as a transition zone between the high mountains and the plains.
