Upwarped mountains are generally the result of broad arching of the crust or sometimes great vertical displacement along a highangle fault. The Black Hills in South Dakota and the Adirondack Mountains in New York are upwarped mountain ranges. Volcanic mountains are the accumulations of large amounts of volcanic lavas and pyroclastic material around the volcanic vent, such as seamounts and stratovolcanoes. The Hawaiian and Aleutian Islands are volcanic mountains. Fault-block mountains result from tensional stress.
Loihi, the newest Hawaiian volcano. The next Hawaiian island that will come into being-already named Loihi-is building on the seafloor southeast of Kilauea. Its top is 1000 m (3000 feet) below the water surface, and it will break the surface in the next 10,000 to 100,000 years.
