Where are atolls usually located around? around submerged, extinct volcanoes around rich iron deposits around larger continents around population centers?

An atoll is a ring-shape coral reef that is usually located around extinct volcanoes that have been partially submerged in seawater. Beside extinct volcanoes, atolls are around found around sea mountains. The Pacific and the Indian ocean contain most of the atolls in the world.
