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.
Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle. (The mantle is the hotter layer under the crust.). Tectonic plates can transport both continental crust and oceanic crust, or they may be made of only one kind of crust.Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust.ectonic plates can transport both continental crust and oceanic crust, or they may be made of only one kind of crust.
