The volcanoes that formed the Aleutian Islands are the result of a process called subduction. The Pacfic Plate is sliding or subducting under the northern part of the North American Plate at about 3 inches per year. As this oceanic plate dives into the mantle it takes some seawater with it. The water seeps into the hot rocks of the mantle, lowering the melting point. The resulting molten rock or mantle then rises through the North American Plate then erupts through the North American Plate, forming volcanoes.
