Here's a breakdown:
* Plate Tectonics: The Earth's crust is divided into massive plates that are constantly moving. This movement is driven by heat currents deep within the Earth's mantle.
* Collision: Millions of years ago, the Indian Plate, which was once a separate landmass, started moving northward. It collided with the Eurasian Plate, causing the land to buckle, fold, and uplift.
* Mountain Formation: This intense pressure created the Himalayas, which are still rising today, albeit slowly.
This process, known as orogenesis, is responsible for the formation of most mountain ranges on Earth. The Himalayas are one of the most dramatic examples, showcasing the immense power of tectonic forces.
