The mountains in general suffer the phenomenon of erosion. So new plains generate from the powders that settle on the gorund.  But also the mountains themselves change their aspect. An example is the mountain range of Dolomiti in Trentino, Italy: their history began about 270 millions years ago and now people can see directly this phenomenon.

The New World is one of the names used for the Western Hemisphere, specifically America. The term originated in the late 15th century, when America had been recently discovered by European explorers, expanding the geographical horizon of the European middle Ages which had thought of the world as consisting of Europe, Asia, and Africa (collectively, the Old World).

NEW is a common prefix in toponymy. For example the most famous places that uses the prefix "new" are:

• New York
• New Dehli
• New Zealand
• New-Castle
