Geography of the Marshall Islands
The Marshall Islands consist of two archipelagic island chains of 30 atolls and 1,152 islands, which form two parallel groups—the "Ratak" (sunrise) chain and the "Ralik" (sunset) chain. The Marshalls are located in the North Pacific Ocean and share maritime boundaries with Micronesia and Kiribati. Two-thirds of the nation's population lives in the capital of Majuro and the settlement of Ebeye. The outer islands are sparsely populated due to lack of employment opportunities and economic development. Statistics. The country is located about one-half of the way from Hawaii to Papua New  Guinea. The archipelago includes the atolls of Bikini, Enewetak, Kwajalein, Majuro, Rongelap, and Utirik. The total area of the islands is equal to the size of the City of Washington, DC. The largest atoll with a land area of is Kwajalein. The terrain consists of low coral limestone and sand islands. Natural resources include coconut products, marine products, and deep seabed minerals. Current environmental issues are inadequate supplies of potable water; pollution of Majuro lagoon from household waste and discharges from fishing vessels.

Climate. Tropical; hot and humid with a Koeppen-Geiger classification of "Af". The wet season lasts from May to November and the islands border the typhoon belt. Typhoons do pose an infrequent threat from July to mid November. Due to their low elevation, the Marshall Islands are threatened by the potential effects of sea level rise. According to the President of Nauru, the Marshall Islands are the most endangered nation on Earth due to flooding from climate change. A study by the University of Plymouth found that the tides move sediment  to create higher elevation, which may keep the islands habitable. Extreme points. This is a list of the extreme points of the Marshall Islands, the points that are farther north, south, east or west than any other location.
