An isthmus ( /ˈɪsθməs/ or /ˈɪsməs/;[1] plural: isthmuses; from Ancient Greek: ἰσθμός, translit. isthmos, lit. 'neck'[2]) is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated.[3] A tombolo is an isthmus that consists of a spit or bar, and a strait is the sea counterpart of an isthmus. Canals are often built across isthmuses, where they may be a particularly advantageous shortcut for marine transport. For example, the Panama Canal
crosses the Isthmus
of Panama, connecting the North Atlantic and Pacific Oceans; the Suez Canal
connects the Mediterranean Sea and the Red Sea, cutting across the western side of the Isthmus
of Suez, formed by the Sinai Peninsula; and the Crinan Canal
crosses the isthmus between Loch Crinan
Loch Crinan
and Loch Gilp, which connects the Kintyre peninsula with the rest of Scotland. Another example is the Welland Canal
in the Niagara Peninsula
Niagara Peninsula
(technically an isthmus). It connects Lake Ontario
Lake Ontario
to Lake Erie. The city of Auckland on the North Island
North Island
in New Zealand
New Zealand
is situated on an isthmus. See also[edit]
