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 Earthâs crust and upper mantle (lithosphere) is divided into many plates, which are in constant motion. Where plate edges meet and one plate may slide past another, one plate may be driven beneath another (subduction). Upwelling volcanic material pushes plates apart at mid-ocean ridges. Continental plates are made of less dense rocks (granites) that are thicker than oceanic plates (basalts) and thus, ârideâ higher than oceanic plates.
