Solomon Islands is an island country in the South Pacific Ocean, that lies east of Papua New Guinea.
Islands
[edit]The major part of the nation of Solomon Islands is the mountainous volcanic islands of the Solomon Islands (archipelago), which includes Choiseul, the Shortland Islands, the New Georgia Islands, Santa Isabel, the Russell Islands, the Florida Islands, Tulagi, Malaita, Maramasike, Ulawa, Owaraha (Santa Ana), Makira (San Cristobal), and the main island of Guadalcanal. (The largest island in the archipelago is Bougainville, but it is politically an autonomous region of the neighbouring country of Papua New Guinea.) Solomon Islands also includes isolated low-lying atolls and volcanic islands such as Sikaiana, Rennell Island, Bellona Island, the Santa Cruz Islands and the remote, tiny outliers, Tikopia, Anuta, and Fatutaka.
The distance between the most western and most eastern islands is about 1,500 km (930 mi). Especially the Santa Cruz Islands, north of Vanuatu, are isolated at more than 200 km (120 mi) from the other islands. The total land size is 29,000 km2 (11,000 sq mi).[3][4] It has the 22nd largest Exclusive Economic Zone of 1,589,477 km2 (613,701 sq mi).
Geology and ecology
[edit].svg)
Volcanoes with varying degrees of activity are situated on some of the larger islands, while many of the smaller islands are simply tiny atolls covered in sand and palm trees.
The baseline survey of marine biodiversity in the Solomon Islands that was carried out in 2004,[5] found 474 species of corals in the Solomons as well as nine species which could be new to science. This is the second highest diversity of corals in the World, second only to the Raja Ampat Islands in eastern Indonesia.[6]
Climate
[edit]The climate is tropical, though temperatures are rarely extreme due to cooling winds blowing off the surrounding seas. Daytime temperatures are normally 25 to 32 °C (77 to 90 °F). From April to October (the dry season), the southeast trade winds blow, gusting at times up to 30 knots (56 km/h) or more.
November to March is the wet season—the northwest monsoon—typically warmer and wetter. Cyclones arise in the Coral Sea and the area of the Solomon Islands, but they usually veer toward Vanuatu and New Caledonia or down the coast of Australia.
