Which major global mountain range system, formed by the collision of the Indian Plate and the Eurasian Plate, shares its exact tectonic origin with the mountains of Sikkim?

💡 Solution & Explanation

The Himalayan mountain system is formed by the ongoing continent-continent collision between the Indian Plate and the Eurasian Plate, which created the towering peaks and deep valleys found across Sikkim. The Andes were formed by oceanic-continental subduction in South America, the Rockies by Laramide orogeny in North America, and the Great Dividing Range in Australia through ancient tectonic rifting. This active tectonic convergence makes the entire Himalayan arc seismically vulnerable and structurally complex.
