Landscape
The Marshall Islands consists of low coral atolls and separate reef islands in the Pacific. Most land occurs as narrow strips around lagoons, with deep ocean between the island groups. There are no high mountain interiors to collect rainfall.
Majuro is an inhabited atoll where settlement follows a narrow reef rim. Other atolls contain more scattered islands and extensive lagoon water. The geographic unit is therefore often the whole reef-and-lagoon system rather than one continuous island.
