man·tle1 / ˈmantl/ • n. 1. a loose sleeveless cloak or shawl, worn esp. by women. ∎ fig. a covering of a specified sort: the houses were covered with a thick mantle of snow. ∎ (also gas mantle) a fragile mesh cover fixed around a gas jet, kerosene wick, etc., to give an incandescent light when heated. ∎ Ornithol. a bird's back, scapulars, and wing coverts, esp. when of a distinctive color. ∎ Zool. an outer or enclosing layer of tissue, esp. (in mollusks, cirripedes, and brachiopods) a fold of skin enclosing the viscera and secreting the substance that produces the shell. 2. an important role or responsibility that passes from one person to another: the second son has now assumed his father's mantle. 3. Geol. the region of the earth's interior between the crust and the core, believed to consist of hot, dense silicate rocks (mainly peridotite). ∎ the corresponding part of another planetary body: the lunar mantle. • v. 1. [tr.] poetic/lit. clothe in or as if in a mantle; cloak or envelop: heavy mists mantled the forested slopes. ∎ archaic (of blood) suffuse (the face): a warm pink mounted to the girl's cheeks and mantled her brow. ∎ [intr.] (of the face) glow with a blush: her rich face mantling with emotion. ∎ [intr.] archaic (of a liquid) become covered with a head or froth. 2.

mantle
mantle portion of the earth 's interior lying beneath the crust and above the core. No direct observation of the mantle, or its upper boundary, has been made; its boundaries have been determined solely by abrupt changes in the velocities and character of seismic waves passing through the earth's interior (see seismology ). Samples of the upper mantle may be provided by some volcanic eruptions in ocean areas, e.g., the Hawaiian Islands. The continental and ocean crusts, along with part of the solid upper mantle, make up the lithosphere to a depth of about 62 mi (100 km). Within the lithosphere is the Mohorovičić discontinuity, or Moho, considered to be the mantle's upper surface, at depths ranging from 4 to 43 mi (7 to 70 km). Analysis of seismic waves indicates that rocks below the Moho are less rigid and slightly more dense than rocks making up the crust. A zone of low seismic velocity and rigidity just below the lithosphere, called the asthenosphere , is present in the upper part of the mantle, from 62 mi (100 km) to 156 mi (250 km). Its presence is of critical importance to plate tectonics . The mantle continues to the Gutenberg discontinuity at the liquid outer core, with the base of the mantle located about 1,800 mi (2,900 km) below the earth's surface. The entire mantle constitutes about 84% of the earth by volume. Its composition is thought to be similar to peridotite, an igneous rock of mostly magnesium-rich silicate. |

Mantle
MantleThe mantle was an all-purpose overgarment that was worn consistently throughout the Middle Ages (c. 500–c. 1500). Mantles were extremely simple: they consisted of a large piece of cloth, rectangular, semicircular, or circular, that was wrapped across the shoulders and fastened. In the eleventh and twelfth centuries the mantle was typically fastened at the right shoulder with a small metal clasp or brooch. By the late twelfth century, however, people began to drape the mantle over both shoulders and fasten it at the center of the chest. New fastenings included cords that tied or a button and loop. The simplicity of the mantle made it very adaptable. Poor people might wear a mantle of undyed wool with a crude clasp. But wealthy people could wear mantles made of rich silk, trimmed with soft fur, and fastened with an expensive jeweled brooch. Some form of the mantle has been worn throughout the history of human dress: the basic form had been worn in ancient Greece and Rome, and were called chlaina, diplax, and chlamys, and people still wear capes to this day.

mantle
mantle Layer of the Earth between the crust and the core, which extends to a depth of 2890km (1795mi). The mantle forms the greatest bulk of the Earth: 82% of its volume and 68% of its mass. The uppermost part is rigid, solid and brittle and, together with the Earth's crust, forms the lithosphere. Between a depth of about 60km (40mi) to 200km (125mi), the mantle has a soft zone that is called the asthenosphere. Here, temperature and pressure are in balance so that much of the mantle material is near melting point or partly melted and capable of flowing. The remainder of the mantle is thought to be more solid but still capable of creeping flow. In the lower mantle, several changes in seismic velocity can be detected. The chemical constitution of the mantle is uncertain, but it is thought to be made up of iron-magnesian silicates.

mantle
mantle
1. (pallium) In molluscs and some brachiopods (in which it is known as the mantle lobe), a fold of skin on the dorsal surface that encloses a space (the mantle cavity) containing the gills. The mantle is responsible for the secretion of the shell. 2. In Cirripedia (barnacles), the name often given to the carapace. 3. The zone lying between the Earth's crust and core, approximately 2300 km thick, and representing about 84 per cent of the Earth's volume and 68 per cent of its mass. |

A mantle is present in most terrestrial planets and the Moon, but is of a different composition in each case. 2. (pallium) In Brachiopoda and Mollusca, a layer of tissue that covers the body and is responsible for the secretion of the shell. |
