A classic example of continental-continental plate convergence is the collision of the Indian and Eurasian plates, which is ongoing and has resulted in the formation of the Himalayan mountain range.

Here's why:

* The Indian plate was originally a separate landmass that drifted northwards.

* The Eurasian plate was already in its current position.

* The collision began millions of years ago and continues today.

* The immense pressure from the converging plates caused the land to buckle and fold upwards, creating the highest mountain range on Earth.

This example demonstrates the dramatic and long-lasting impact of continental-continental plate convergence.
