A mountain is a geological formation that rises much higher than the surrounding land, sometimes many kilometers high. They are significantly taller than hills.
Mountains are a common occurrence on many planets, both inhabited and not.
In the early 2370s, a Klingon civilian transport crashed in a mountainous area of the planet Galorda Prime. (DS9: "Rules of Engagement")
On Earth, the tallest mountain is Mount Everest in the Himalayas. Also very tall is the Tibetan plateau. Ireland, on Earth, is known for not having any mountains, just hills.
Trapped on Torga IV in the Gamma Quadrant, Enrique Muñiz called Miles O'Brien a "mountain man... an old mountain man", to which O'Brien took offense. (DS9: "The Ship")
