Passage: Bahrain is a generally flat and arid archipelago in the Persian Gulf. It consists of a low desert plain rising gently to a low central escarpment with the highest point the 134 m (440 ft) Mountain of Smoke (Jabal ad Dukhan). Bahrain had a total area of 665 km2 (257 sq mi) but due to land reclamation, the area increased to 765 km2 (295 sq mi), which is slightly larger than Hamburg or the Isle of Man.Often described as an archipelago of 33 islands, extensive land reclamation projects have changed this; by August 2008 the number of islands and island groups had increased to 84. Bahrain does not share a land boundary with another country but does have a 161 km (100 mi) coastline. The country also claims a further 22 km (12 nmi) of territorial sea and a 44 km (24 nmi) contiguous zone. Bahrain's largest islands are Bahrain Island, the Hawar Islands, Muharraq Island, Umm an Nasan, and Sitra. Bahrain has mild winters and very hot, humid summers. The country's natural resources include large quantities of oil and natural gas as well as fish in the offshore waters. Arable land constitutes only 2.82% of the total area.
