In which direction is Hawaii's chain of islands moving?
A map of the Pacific Ocean shows a chain of islands. There is a compass rose in the bottom left corner with an arrow for north pointing toward the top of the map. The first island, labeled Hawaii is in the bottom right corner. Moving toward the upper left corner are the following islands in order: Kahoolawe, Maui, Lanai, Molkokai, Oahu, Niihau and ending with Kauai in the uper left corner of the map.
