WebAug 20, 2016 · The five mechanical layers of the earth are defined by how the layers move. The layers can be described as rigid, plastic or liquid in consistency. The outermost mechanical layer is the lithosphere. The lithosphere is rigid, and it includes the crust and the uppermost part of the mantle.
