Word of the day: What is an atoll? [PICTURES]

If you hate Mondays, come with us on a daydreaming adventure involving turquoise blue water and sandy white beaches.


Rest assured, if you’ve asked Google today ‘what is an atoll‘, you’re not alone. Today’s Wordle has left many players confused.

I went with arise, touch and atomy (skeleton or emaciated body) before atoll came to mind.

So, exactly what is an atoll? Spoiler alert: It has nothing to do with e-tolls.

Word of the day: Atoll

An atoll – sometimes referred to as a coral atoll – is a ring-shaped coral reef encircling a lagoon either partially or completely.

It is also used to refer to an island or a series of islets. They can pose a danger to seafarers and have caused many a ship to run aground throughout history.

The biggest coral islet in the world is the Great Chagos Bank in the Indian Ocean, taking up approximately 12,642 square kilometres.

Can you visit these islets?

Most atolls are unnamed and uninhabited (or sparsely populated). They are also impossible to gain access to in many instances.

However, the atoll near Mokuauia Island, also known as Goat Island, is incredibly easy to access (if one could afford a plane ticket to Hawaii).

The islet is a Hawaii State Seabird Sanctuary, with lithified dunes on the northeast shore of Oahu. The island also has 16 native plant species.

The dunes are off-limits to the public but the island’s three main beaches attract thousands of tourists each year.

The Cocos Island – also known as Keeling Islands are situated in the Indian Ocean, in Australian external territory midway to Sri Lanka.

The Cocos comprises a small archipelago and two atolls midway between Australia and Sri Lanka, which make up 27 coral islands in total.

Cocos has a population of around 600, and only two of the 27 islands – West Island and Home Island – are inhabited.
