The Himalayas, spanning nearly 2,500 km across India, Nepal, Bhutan, Tibet and Pakistan, are home to some of the world’s highest peaks including Mount Everest. They consist of three main regions – the Outer Himalayas, the Lesser Himalayas and the Greater Himalayas. The range was formed over 50 million years ago as a result of the collision between the Indian and Eurasian plates. The outer region is predominantly composed of soft sedimentary rocks, while the middle section consists of dense, forested valleys and harder rocks such as granite and gneiss. The Greater Himalayas are the highest and most prominent of the three regions.
Understanding the Topography of the Himalayas: A Geographical Perspective
The Himalayas are one of the most spectacular mountain ranges on the planet. Stretching for almost 2,500 km across India, Nepal, Bhutan, Tibet, and Pakistan, the range is home to some of the world’s highest peaks, including Mount Everest. However, the topography of the Himalayas is much more than just towering mountains and snow-capped peaks. In this article, we will take a closer look at the geographical features that make up the Himalayas.
Geological Formation
The Himalayas were formed approximately 50 million years ago as a result of the collision between the Indian and Eurasian plates. The Indian plate, which was once an independent landmass, began moving towards the Eurasian plate around 70 million years ago. This collision forced the Indian plate to dive beneath the Eurasian plate, and the intense heat and pressure caused by this collision spurred the formation of the Himalayas.
Topographical Features
The Himalayas are often described as a “chain of mountains” because they consist of several mountain ranges. The topography of the Himalayas can be divided into three main regions:
The Outer Himalayas
Also known as the Shivalik Range, the Outer Himalayas are the southernmost range of the Himalayas. This region consists of low-lying hills and foothills that border the Indo-Gangetic Plains. The Outer Himalayas are predominantly made up of soft sedimentary rocks such as shale, sandstone, and limestone.
The Lesser Himalayas
The Lesser Himalayas, also known as middle Himalayas, is the second-highest region of the Himalayas. This region consists of several parallel ranges, which form densely forested valleys. The Lesser Himalayas are composed of harder rocks such as granite and gneiss, which are more resistant to erosion than the softer rocks found in the Outer Himalayas.
The Greater Himalayas
The Greater Himalayas are the highest and most prominent region of the Himalayas. This region consists of several parallel ranges, which stretch from Nanga Parbat in Pakistan to Namcha Barwa in Tibet. The Greater Himalayas are formed by the collision between the Indian and Eurasian plates, which has caused intense folding and faulting of the rocks. The highest peaks of the Himalayas, such as Mount Everest, are found in the Greater Himalayas.
