The Formation of a Giant: Tectonic Plates and the Himalayas

The Himalayas' towering presence is a direct result of the collision between the Indian and Eurasian tectonic plates. This ongoing geological process, which began approximately 50 million years ago, continues to shape the landscape. Here's a simplified breakdown:

Continental Collision: The Indian plate, once a separate landmass, drifted northward and collided with the Eurasian plate.
Compression and Uplift: The immense pressure from the collision caused the Earth's crust to buckle and fold, resulting in the uplift of the Himalayan range.
Ongoing Process: The Indian plate continues to push against the Eurasian plate, causing the Himalayas to rise approximately 5 millimeters each year. This also leads to frequent seismic activity in the region.

On a map, understanding the tectonic plate boundaries helps visualize the forces at play beneath the surface. Fault lines and seismic zones are often marked, highlighting the areas prone to earthquakes. The geological map reveals the complex rock formations and the history of uplift and erosion that have sculpted the mountains over millions of years.

A Multi-Layered System: Subranges and Key Peaks
