Here's a breakdown:
* Plate Tectonics: The Earth's crust is made up of large, moving plates.
* Continental-Continental Collisions: When two continental plates collide, neither plate is dense enough to subduct (slide) under the other. Instead, the immense pressure causes the land to buckle, fold, and uplift, creating mountains.
* Example: The Himalayas, the world's highest mountain range, were formed when the Indian Plate collided with the Eurasian Plate.
Other factors that contribute to mountain formation:
* Volcanic Activity: Volcanoes can also contribute to the formation of mountains, especially when they erupt repeatedly over a long period.
* Erosion: While erosion wears mountains down, it also plays a role in shaping their final form and creating dramatic features like canyons and valleys.
So, while other factors play a role, the collision of continental plates is the primary driver behind the formation of the highest mountains on Earth.
