The average starting wage of an apprentice is about 50% of a journey worker's rate of pay. Programs are required to progressively increase the apprentices wages provided the on-the-job training and school performance is satisfactory and in accordance with apprenticeship committee.
The Aleutian Trench formed as the Pacific Plate converged with the North American Plate forcing the Pacific's oceanic plate into the mantle because the Pacific Plate is denser than the North American Plate. The Aleutian Trench and other Trenches formed a subduction zone by converging with other plate tectonics.
The Aleutian Trench is effectively buried east of Kodiak Island in the Gulf of Alaska. There the ocean floor is smooth and flat. To the west, farther from the sediment supply of Alaska, the trench reaches depths of more than 7 km (about 4 miles).
