Un''''isola tidale''', dall'inglese ''tide'', marea, è un'isola collegata al continente (o ad altra isola più grande) da un [[Tombolo_(spiaggia)|tombolo]], una banda sabbiosa che periodicamente viene ricoperta dalle acque durante l'[[marea|alta marea]], e come tale viene definito [[piano mesolitorale]].

Riga 6 ⟶ 5:

Sono pertanto isole accessibili soltanto nei periodi di bassa marea, tramite il loro tombolo sul quale viene spesso costruito un argine istmico, o diga, per facilitarne l'accesso, diga che viene interamente sommersa dall'alta marea, isolandole così del tutto.

A '''tidal island''' is a piece of land that is connected to the mainland by a natural or man-made [[causeway]] that is exposed at low [[tide]] and submerged at high tide. Because of the mystique surrounding tidal islands many of them have been sites of [[place of worship|religious worship]], such as [[Mont Saint Michel]] with its [[Order of Saint Benedict|Benedictine]] [[Abbey]]. Tidal islands are also commonly the sites of [[fortresses]], due to their natural fortifications.

The former [[Bennelong Point, New South Wales|Bennelong Island]] in [[Sydney]], [[Australia]] was developed into [[Bennelong Point]] and is now the ___location of the [[Sydney Opera House]].
