When studying global mountain building processes (orogeny), the Himalayas—including the ranges traversing Arunachal Pradesh—are classified as which specific type of mountain range?

💡 Solution & Explanation

The Himalayas are classic young fold mountains formed by the ongoing convergent collision between the Indian continental plate and the Eurasian continental plate. Volcanic mountains form over mantle plumes or subduction zones, block mountains form via faulting (like the Vosges or Black Forest), and dome mountains result from magma pushing up sedimentary layers from below. This fundamental geomorphological distinction is foundational to earth sciences.
