1. The Himalayas: This majestic mountain range, home to the world's highest peak, Mount Everest, is a prime example of folded mountains. It was formed by the collision of the Indian and Eurasian tectonic plates. The immense pressure from this collision caused the land to buckle and fold upwards, creating the towering peaks we see today.

2. The Appalachian Mountains: These ancient mountains in eastern North America were formed during the Paleozoic Era, when the North American and African continents collided. The intense pressure from this collision caused the sedimentary rocks to fold and uplift, resulting in the Appalachian range.
