Here's a breakdown of how this happened:
* Millions of years ago: The Indian plate was a separate landmass, moving northward.
* Collision: Around 50 million years ago, the Indian plate collided with the Eurasian plate.
* Subduction: The denser Indian plate was forced under the Eurasian plate, a process called subduction.
* Uplift: The immense pressure from the collision caused the Eurasian plate to buckle and fold upward, creating the Himalayan mountain range.
* Continuing Growth: The Indian plate is still moving northward, pushing against the Eurasian plate, causing the Himalayas to continue growing at a rate of a few millimeters per year.
This process is a prime example of how plate tectonics shapes the Earth's surface, creating dramatic landforms like the Himalayas.
