An island (or “île” in French, formerly “isle”) is a landmass surrounded by water, either permanently or sometimes temporarily, depending on the tides.
You can collect periwinkles when the water recedes.
The water surrounding islands can come from an ocean, a sea, a lake, or a river. Islands can be temporary (such as sandbanks) or permanent, isolated or grouped with other islands, forming an archipelago.
Recording water retreating from the sand, freshwater from a stream merging with saltwater, periwinkles climbing over each other in a bowl filled with ocean water, effervescent substances in a jar of water.
Islands can be connected to other islands or to a continent by a causeway, a bridge, or a tunnel; however, this does not erase their insular nature. This is different from an island naturally or artificially connected to another island or a continent by an isthmus, a tombolo, a dike, or through isostasy.
