A raised shoreline is an ancient shoreline exposed above current water level.〔http://www.encyclopedia.com/doc/1O112-raisedshorelines.html〕 These landforms are formed by a relative change in sea level due to global sea level rise, isostatic rebound, and/or tectonic uplift. These surfaces are usually exposed above modern sea level when a heavily glaciated area experiences a glacial retreat, causing water levels to rise. This area will then experience post-glacial rebound, effectively raising the shoreline surface. Examples of raised shorelines can be found along the coasts of formerly glaciated areas in Ireland〔http://www.askaboutireland.ie/.../changing-sea-levels/〕 and Scotland, as well as in North America. Raised shorelines are exposed at various locations around the Puget Sound of Washington State.〔http://www3.interscience.wiley.com/journal/118781323/abstract〕 ==Related links== *Isostasy *Landform *Machair *Marine terrace *Parallel Roads of Glen Roy *Raised beaches *Terrace (geology) *Terrace (geology) *wave-cut platform 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「Raised shoreline」の詳細全文を読む スポンサード リンク
