Is there a standard definition of the term "mountain"?

Question

Is there any standard internationally recognizable definition of the term "mountain"? If international texts describe some terrain as mountains, do they use some international definition of the term, or do they use the local definitions? For example, in Poland geographers usually agree that terrain is called mountains when its peaks are at least 600 meters above sea level. This makes, for example, the Świętokrzyskie Mountains 'mountains', although only a single peak is above 600m. But there are other definitions that are bases on the geological structure of the terrain, not on the height. Germans, from what I know, use a definition based on 'Reliefenergie', so the relative height difference for every square kilometer, independent of the absolute height. What criteria are usually used to call a terrain 'mountains' in international community? For example, what would we use on this site?

Answer 1

In general terms,

Both are defined as regions of landscape that are higher than the area surrounding them.

A mountain will be rocky and uneven, and typically, geologists consider any formation over 1,000 feet (relative to the surrounding area) to be a mountain.

A hill will be smooth and below 1,000 feet (relative to the surrounding area.

Although other countries and cultures may have different definitions or determining factors for what is considered a "mountain". The general consensus is based on how the formation appears relative to its surrounding area.
