Is Alaska near a plate boundary?

Alaska’s high mountains, volcanoes, and earthquakes result from this plate movement, called plate tectonics. The state’s location at the boundary between two major plates—the North American plate and Pacific plate—makes Alaska one of the most geologically active regions in the world.

Which type of convergent plate boundary formed the Aleutian Islands of Alaska?

Examples of ocean-ocean convergent zones are subduction of the Pacific Plate south of Alaska (creating the Aleutian Islands) and under the Philippine Plate, where it creates the Marianas Trench, the deepest part of the ocean.
