ETYM Old Eng. mantel, Old Fren. mantel, French manteau, from Latin mantellum, mantelum, a cloth, napkin, cloak, mantle (cf. mantele, mantile, towel, napkin); prob. from manus hand + the root of tela cloth. Related to Manual, Textile, Mandil, Mantel, Mantilla.
Intermediate zone of the Earth between the crust and the core, accounting for 82% of the Earth's volume. It is thought to consist of silicate minerals such as olivine.
The mantle is subdivided into three shells: the upper mantle that extends to 400 km/250 mi beneath the surface; the transition zone 400–650 km/250–400 mi down; and the lower mantle 650–2,900 km/400–1,800 mi down.
It mantle is separated from the crust by the Mohorovicic discontinuity, and from the core by the Gutenberg discontinuity. The patterns of seismic waves passing through it show that its uppermost as well as its lower layers are solid.
However, from 72 km/45 mi to 250 km/155 mi in depth is a zone through which seismic waves pass more slowly (the “low-velocity zone”). The inference is that materials in this zone are close to their melting points and they are partly molten. The low-velocity zone is considered the asthenosphere on which the solid lithosphere rides.
