The intense pressure causes the Earth's crust to uplift, creating mountain ranges. This uplift can happen slowly over millions of years.
In some cases, one tectonic plate may be forced beneath another in a process called subduction.
Collisions between plates can cause the Earth's crust to buckle and fold, forming fold mountains.

Mountains undergo a continuous cycle of uplift, erosion and eventually, worn down to hills or plains through geological processes,completing lifecycle
