Mountains are a non man made thing. A mountain is made when two earth plates slide into each other will make one plate slide go up and the other one goes down. A other way a mountains is made when after a volcano has blown it will calm down and ''go to sleep'' it will turn into a mountain.
A mountain can take many forms like a canyons, volcanos, and many other forms.
There are many mountains that have been named like Mount Fuji, the Grand Canyon, the president monument, and so on.
