Here's a breakdown:
* Convergent Plate Boundary: Two tectonic plates move towards each other.
* Continental-Continental Collision: When two continental plates collide, neither is dense enough to subduct (slide) under the other. Instead, the immense pressure forces the land upwards, creating mountain ranges.
In the case of the Himalayas, the Indian Plate is colliding with the Eurasian Plate. This collision is still ongoing, which is why the Himalayas are still rising.
