Geography

reef-maldives-2Geography, Maldives consists of 1,192 coral islands grouped in a double chain of 26 atolls, along the north-south direction, spread over roughly 90,000 square kilometres (35,000 sq mi), making this one of the world's most dispersed countries. It lies between latitudes 1°S and 8°N, and longitudes 72° and 74°E. The atolls are composed of live coral reefs and sand bars, situated atop a submarine ridge 960 kilometres (600 mi) long that rises abruptly from the depths of the Indian Ocean and runs north to south. Only near the southern end of this natural coral barricade do two open passages permit safe ship navigation from one side of the Indian Ocean to the other through the territorial waters of Maldives. For administrative purposes the Maldivian government organised these atolls into twenty one administrative divisions. The largest island of Maldives is Gan, which belongs to Laamu Atoll or Hahdhummathi Maldives. In Addu Atoll the westernmost islands are connected by roads over the reef (collectively called Link Road) and the total length of the road is 14 km (9 mi).

Maldives is the lowest country in the world, with a maximum natural ground level of only 2.4 metres (7 ft 10 in), with the average being only 1.5 metres (4 ft 11 in) above sea level, although in areas where construction exists, this has been increased to several metres. However, more than 80 per cent of the country's land is composed of coral islands that rise less than one metre above sea level.

The reef is composed of coral debris and living coral. This acts as a natural barrier against the sea, forming lagoons. Other islands, set at a distance and parallel to the reef, have their own protective fringe of reef. An opening in the surrounding coral barrier allows access to the calmer lagoon waters. The barrier reefs of the islands protect them from the storms and high waves of the Indian Ocean.

The limited vegetation and land wildlife is supplemented by the abundance of marine life. The waters around the Maldives are abundant in rare species of biological and commercial value. Tuna fisheries are one of the main commercial resources. The Maldives have an amazing diversity of sea life, with corals and over 2,000 species of fish, ranging from reef fish to reef sharks, moray eels, and a wide variety of rays: Manta rays, Stingrays, and Eagle rays. The Maldivian waters also host whale sharks and hawksbill and green sea turtles.
