Mountains technically do not "grow", they uplift. This is caused by tectonic plate activity when plates collide, fold, fault, or due to volcanic activity (like in Hawai'i). This is called Orogeny. Orogenesis is the process.
Root info:
oros= Mountain
genesis = origin.
So, this word lietrally means "the creation of mountains"
