* Continental Plates Collide: When two continental plates collide, they are too buoyant to subduct (slide one under the other). Instead, the immense pressure causes the land to buckle, fold, and uplift, creating mountains.
* Folding and Faulting: The intense pressure causes the rock layers to bend (fold) and break (fault).
* Uplifting: The folding and faulting push the land upwards, creating towering mountain ranges.
Examples of Fold Mountains:
* The Himalayas: Formed by the collision of the Indian and Eurasian plates.
* The Alps: Formed by the collision of the African and Eurasian plates.
* The Andes Mountains: Formed by the collision of the Nazca and South American plates (although the Nazca plate is oceanic, it's colliding with the continental South American plate, which is what causes the fold mountains).
* The Appalachian Mountains: While older and eroded, they were originally formed by the collision of ancient continents.
Key Points:
* Fold mountains are often characterized by their jagged peaks, deep valleys, and steep slopes.
* The process of mountain formation is slow and takes millions of years.
* The collision of continental plates is a powerful force that shapes the Earth's surface.
