covered with or as if with clothes or a wrap or cloak; "leaf-clothed trees"; "fog-cloaked meadows"; "a beam draped with cobwebs"; "cloud-wrapped peaks"
(From the base of the crust to the outer core 2,900 km deep) There are upper and lower layers In the 250 km below the surface, it becomes plastic: this part is called the asthenosphere, over which the lithosphere floats The thickness of the lithosphere varies between 80 and 120 km It is more rigid and its temperature can reach 1,500°C
The layer of a planet between the core and the crust In the Earth, the mantle is about 2900 km thick and is composed rocks of iron and magnesium combined with silicon and oxygen
A portion of the body wall of a mollusc In snails, clams and other molluscs with shells, the mantle secretes the shell In octopus and squid, the mantle is the outside of the body
If you take on the mantle of something such as a profession or an important job, you take on the responsibilities and duties which must be fulfilled by anyone who has this profession or job. Glasgow has broadened its appeal since taking on the mantle of European City of Culture in 1990
That part of the Earth beneath the crust but above the molten iron/nickel core The mantle makes up the greatest volume of the Earth and is composed of iron-magnesium silicate minerals
The layer of the earth lying between the CRUST and the CORE The mantle extends between depths of about 30 kilometers (19 miles) in the continential areas and 2,800 km (1,790 miles), where the core begins
The layer of rock that lies between the crust and the outer core of the Earth It is approximately 2900 kilometers thick and is the largest of the Earth's major layers
The middle layer of the Earth, lying just below the crust and consisting of relatively dense rocks The mantle is divided into two sections, the upper mantle and the lower mantle; the lower mantle has greater density than the upper mantle See also core and crust
that portion of the Earth below the crust and reaching to about 2,780 km, where a transition zone of about 100 km thickness separates it from the core It has a high iron, magnesium and nickel composition
(Geology) The division of the earth's interior between the core and the crust It is composed mainly of silicate rock and is around 2,900 kilometers (1,800 miles) thick
A rock layer, about 2,894 kilometers thick, between the Earth's crust and core Like the crust, the upper part of the mantle is relatively brittle Together, the upper brittle part of the mantle and the crust form tectonic plates
The solid bulk of the earth's interior, ranging from the core boundary, at 3400 km, to the crust, (about 6400 km) The mantle is made up of a mixture of metamorphic rocks, with minerals rich in Mg and Fe Mantle samples are denser than crustal rocks (3 3 and up, in contrast to 3 0 and less) The rocky meteorites, the moon, and most of Mars are basically the same material as the earth's mantle Subtle compositional and isotopic differences have been used to work out the early history of the rocky planets
(zoology) a protective layer of epidermis in mollusks or brachiopods that secretes a substance forming the shell the cloak as a symbol of authority; "place the mantle of authority on younger shoulders"
A mantle of something is a layer of it covering a surface, for example a layer of snow on the ground. The parks and squares looked grim under a mantle of soot and ash. = blanket see also mantel. to cover the surface of something. That part of the Earth that lies beneath the crust and above the central core. On average, the mantle begins about 22 mi (35 km) below the surface and ends at a depth of about 1,800 mi (2,900 km). Predominant in the rock material are olivines, pyroxenes, and the silicate perovskite, a dense form of enstatite
