![]() The three major river systems of India- Indus, Ganga and the Brahmaputra along with their tributaries have fed the foothills of the Himalayas. See more interesting facts about Himalayas here. The Eastern Hills or the Purvanchal covering North Bengal, and northernmost parts of the North Eastern states. ![]() The Outer Himalayas or the Shiwalik Range.The Lesser Himalayas with average peaks rising as high as 4000 meters.The Greater Himalayas or the Himadri, with average peaks reaching up to 6000 meters above the sea-level.Furthermore, the entire mountain belt is divided into three main sections. One of the most significant of all the physical features of India, the Himalayas vary in width between 400 Km to 150 KM. This helps keep the cold arctic winds from reaching the tropical landmass. Since they stretch across 2500 KM from Kashmir in the north, through Arunachal Pradesh in the North East, these mountains form an arc. Though geologically young, the Himalayan Mountains are the loftiest and the most rugged of the world. The northernmost landscape of the country highlights the fold mountains of the Himalayas. The physical features of India can be divided into six broad categories according to their physiographic forms: Himalayan Mountains Thereafter, many such geological events led to the formation of each of the varied physical features of India. Consequently, this collision caused the landmass to fold and become, what we know as the Himalayas today. One such piece- the Indo-Australian plate started shifting northwards, where it collided with the Eurasian plate (now Europe). Over hundreds of years of shifting landmass and ocean currents broke this landmass into multiple pieces. Millions of years ago, the Peninsular Plateau region (the oldest landmass) was a part of the Gondwana Land which covered India, Australia, South Africa, and South America.
