Aleutian Trench

There are several other ways that the collision of the two plates is currently making the Alaska we see today. Where the heavier Pacific Plate collides with the lighter North American Plate, it is forced under the 60-mile-thick North American Plate. At this subduction zone, a huge trough called the Aleutian Trench is created in the ocean.  The Aleutian Trench is over 2,000 miles long, 20 to 100 miles wide, and has a depth of over 25,000 feet.  This is deeper than Denali is tall, and one of the deepest places on Earth!
