INDIAN GEOGRAPHY

Detailed explanation-1: -The Greater Himalayas formed due to the collision of two continental plates that is the Indian plate and Eurasian plate. As we know that continental plates composed of granitic rocks that is why the Greater Himalayas are composed of granite.

Detailed explanation-2: -The core of this part of Himalayas is composed of granite. It is perennially snow bound, and a number of glaciers descend from this range. The range lying to the south of the Himadri forms the most rugged mountain system and is known as Himachal or lesser Himalaya.

Detailed explanation-3: -The most continuous range of the Himalayas is called the Inner or Greater Himalayas, or the Himadri. The northernmost range of the Greater Himalayas consists of the loftiest and the most prominent peaks with asymmetrical folds. The core of Himalayan mountains is composed of granite.

Detailed explanation-4: -Granite makes up the Greater Himalayas’ or Himadri’s core.

Detailed explanation-5: -The Higher Himalaya, the backbone of the Himalayan mountains, is made up of 10-20 km-thick metamorphic rocks (schist and gneiss) and granites situated at altitudes of 3000 m to over 8000 m. These rocks are Proterozoic-Cambrian age (2, 000-500 Ma) and belong to the continental crust of the Indian plate.
