Summarize this article for a 10 year old
The coral reefs of Tuvalu consist of three reef islands and six atolls,[1] containing approximately 710 km2 (270 sq mi) of reef platforms.[2] The islands of the Tuvalu archipelago are spread out between the latitude of 5° to 10° south and longitude of 176° to 180°, west of the International Date Line.[1] The islands of Tuvalu are volcanic in origin. On the atolls, an annular reef rim surrounds the lagoon, and may include natural reef channels.[3] The reef islands have a different structure to the atolls, and are described as reef platforms as they are smaller tabular reef platforms that do not have a salt-water lagoon,[4] although they may have a completely closed rim of dry land, with the remnants of a lagoon that has no direct connection to the open sea or that may be drying up.[5]
