Final answer:
Orogenesis is the process of mountain building caused by tectonic plate collisions.
Step-by-step explanation:
The process of mountain building is called orogenesis. It occurs when tectonic plates collide and cause the Earth's crust to buckle, fold, and uplift, forming mountain ranges. There are different types of orogenesis, such as collisional orogenesis, where continental plates collide and form tall, folded mountains like the Himalayas, and volcanic orogenesis, where volcanic activity leads to the formation of mountains like the Andes.
