The Mariana Islands are the southern part of a submerged mountain range that extends 1,565 miles (2,519 km) from Guam to near Japan. Geographically, the Marianas are the northernmost islands of a larger island group called Micronesia, situated between 13° and 21°N latitude and 144° and 146°E longitude.

The Mariana Islands have a total land area of 389 square miles (1007 km²).[2] They are composed of two administrative units:
• Guam is a US territory.
• The Northern Mariana Islands (including the islands of Saipan, Tinian and Rota) make up a Commonwealth of the United States.

The island chain geographically consists of two subgroups, a northern group of ten volcanic main islands, of which only four (Agrihan, Anatahan, Alamagan and Pagan) are inhabited; and a southern group of five coralline limestone islands (Rota, Guam, Aguijan, Tinian and Saipan), all inhabited except Aguijan. In the northern volcanic group a maximum elevation of about 2,700 feet (820 m) is reached; there are craters showing signs of activity, and earthquakes are not uncommon. Coral reefs fringe the coasts of the southern isles, which are of slight elevation.
Near the islands can be found the lowest point in the Earth's crust, the Mariana Trench.
All the islands except Farallon de Medinilla and Uracas or Farallon de Pajaros (in the northern group) are more or less densely wooded, and the vegetation is dense, much resembling that of the Carolines, and also of the Philippines, from where species of plants have been introduced. Owing to the moistness of the soil cryptogams are numerous, as are also most kinds of grasses. On most of the islands there is a plentiful supply of water.
The fauna of the Marianas, though inferior in number and variety, is similar in character to that of the Carolines, and certain species are indigenous to both island groups. The climate though damp is healthy, while the heat, being tempered by the trade winds, is milder than that of the Philippines; the variations of temperature are not great.
