What is the formation of aleutian type mountains?

Aleutian type mountains are formed by the subduction of the Pacific Plate under the North American Plate along the Aleutian Trench. This subduction leads to the volcanic activity in the region, forming a chain of volcanic islands known as the Aleutian Islands. As the Pacific Plate sinks beneath the North American Plate, magma rises to the surface, creating the characteristic volcanic peaks of the Aleutian Mountains.
