It is the outermost solid part of the earth normally about 8 40 kms thick.
Movement in the mantle caused by variations in heat from the core cause the plates to shift which can cause earthquakes and volcanic eruptions. Isostacyaccording to this concepts blocks of the earths crust because of variations in density would rise to different levels and appear on the surface as mountains plateaux plains or ocean basins see box for details. Movement in the mantle caused by variations in heat from the core cause the plates to shift which can cause earthquakes and volcanic eruptions. In relative terms its thickness is like that of the skin of an apple.
