Likewise, any emergent land in an atoll is also called an islet. * * ''Tidal island'' – Often small islands (not necessarily always islets) which lie off the mainland of an area, being connected to it in low tide and isolated in high tide. * ''River island'' – A small islet within the current of a river. *''Motu, a reef islet formed by broken coral and sand, surrounding an atoll. 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「Islet」の詳細全文を読む スポンサード リンク
