翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク List of rivers by age ： ウィキペディア英語版 List of rivers by age This is a selected list of the oldest rivers on Earth for which there is knowledge about their existence in past times. == Determination of age == The age of a river is difficult to determine. Generally, the age is estimated based primarily upon the age of any mountains it dissects; the age of the sea or ocean to which it eventually outflows can be irrelevant; for example, several rivers of the east side of the Appalachian Mountains are older than the existence of the Atlantic Ocean, which did not exist 130 million years ago. If a river fully dissects a mountain range, then this generally indicates that the river existed at least at the time that the mountain range rose. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of rivers by age」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
