ATOLL Meaning and
Definition
-
An atoll is a ring-shaped coral reef or island formed by the growth of coral reefs on the remnants of an extinct or eroded volcanic island. It is a unique geographical formation typically found in tropical and subtropical regions, particularly in the Pacific and Indian Oceans. Atolls usually consist of a circular or oval-shaped coral reef enclosing a shallow lagoon or open water. The central lagoon is often connected to the surrounding sea through narrow channels or passages. Atolls are created over a long period of time as the coral polyps build skeletal structures on top of the volcanic remnants, which sink and erode over time.
The coral reefs that form the outer ring of an atoll act as a protective barrier against the destructive force of ocean waves, helping to maintain the stability of the central lagoon. They are composed of the calcareous skeletons of coral polyps and provide a habitat for a diverse range of marine life. Atolls are often considered biodiversity hotspots due to the rich variety of marine species they sustain, including fish, mollusks, and crustaceans.
Atolls are often popular tourist destinations due to their stunning and picturesque landscapes, with crystal-clear waters, vibrant coral reefs, and sandy beaches. Additionally, they are of great interest to scientists and researchers studying the effects of climate change, as the rising sea levels and ocean acidification pose significant threats to their fragile ecosystems.

Etymology of ATOLL
The word "atoll" has an interesting etymology. It originates from the Divehi language, spoken in the Maldives, an island nation in the Indian Ocean. The Divehi word "atholhu" (އަތޮޅު) means a ring-shaped coral reef or island formed by coral. This term was later anglicized to "atoll" and introduced into the English language.
The first recorded use of the word "atoll" in English dates back to 1625 in Samuel Purchas' book "Purchas his Pilgrimage". It described a coral island in the Indian Ocean as an "atollon". Over time, the spelling evolved to "atoll", which is the form we use today.
The term gained wider popularity and recognition with the works of Charles Darwin, particularly his book "The Structure and Distribution of Coral Reefs" published in 1842.
