Answer:
The mountains of Himalayan rose to their current height through a process of tectonic plates shifting over a million of years.
Step-by-step explanation:
The Himalayan mountain reached its height due to the process of displacement of tectonic plates. This displacement imposes a pressure on the Earth's surface, which raises this mountain by about 4 centimeters per year. This pressure occurs because for thousands of years the Indian tectonic plate moves slowly under the Eurasian tectonic plate.
