ETYM Latin crusta: cf. Old Fren. crouste, French croűte.
The outermost part of the structure of Earth, consisting of two distinct parts, the oceanic crust and the continental crust. The oceanic crust is on average about 10 km/6.2 mi thick and consists mostly of basaltic types of rock. By contrast, the continental crust is largely made of granite and is more complex in its structure. Because of the movements of plate tectonics, the oceanic crust is in no place older than about 200 million years. However, parts of the continental crust are over 3 billion years old.
Beneath a layer of surface sediment, the oceanic crust is made up of a layer of basalt, followed by a layer of gabbro. The composition of the oceanic crust overall shows a high proportion of silicon and magnesium oxides, hence named sima by geologists. The continental crust varies in thickness from about 40 km/25 mi to 70km/45 mi, being deeper beneath mountain ranges. The surface layer consists of many kinds of sedimentary and igneous rocks. Beneath lies a zone of metamorphic rocks built on a thick layer of granodiorite. Silicon and aluminium oxides dominate the composition and the name sial is given to continental crustal material.
1. A hard outer layer that covers something; SYN. incrustation, encrustation.
2. The outer layer of the Earth; SYN. Earth's crust.
3. The trait of being rude and impertinent; inclined to take liberties; SYN. gall, impertinence, impudence, insolence, cheekiness, freshness.
ETYM Latin depositum, from depositus, p. p. of deponere: cf. French dépôt, Old Fren. depost. Related to Deposit, Depot.
1. The act of depositing; SYN. deposition.
2. The phenomenon of sediment or gravel accumulating; SYN. sedimentation, alluviation.
1. A relatively thin sheetlike expanse or region lying over or under another SYN. level, stratum, sheet.

3. Thin structure composed of a single thickness of cells.
ETYM AS. lâd way, journey, from lîthan to go. Related to Lead to guide, and cf. Load a burden.
A deposit of valuable ore occurring within definite boundaries separating it from surrounding rocks; SYN. load.
Vein of ore. Geological deposit rich in certain minerals, generally consisting of a large vein or set of veins containing ore minerals. A system of veins that can be mined directly forms a lode, for example the mother lode of the California gold rush.
Lodes form because hot hydrothermal liquids and gases from magmas penetrate surrounding rocks, especially when these are limestones; on cooling, veins of ores formed from the magma then extend from the igneous mass into the local rock.
1. A collection of objects laid on top of each other; SYN. heap, mound.
2. A column of wood or steel or concrete that is driven into the ground to provide support for a structure; SYN. spile, piling, stilt.
3. Informal: a large sum of money.
4. The yarn (as in a rug or velvet) that stands up from the weave.
5. Upside-down wedge at an acute angle on a coat of arms
6. In nuclear physics, controlled arrangement of fissionable material for producing a chain reaction.
1. A lump of hard consolidated mineral matter; SYN. stone.
2. Material consisting of the aggregate of minerals like those making up the Earth's crust; SYN. stone.
3. Pitching dangerously to one side; SYN. careen, sway, tilt.
4. Constituent of the Earth's crust, composed of mineral particles and/or materials of organic origin consolidated into a hard mass as igneous, sedimentary, or metamorphic rocks.
1. The act of storing something.
2. The commercial enterprise of storing goods and materials.
ETYM Old Eng. stor, stoor, Old Fren. estor, provisions, supplies, from estorer to store. Related to Store.
Or shop; A building or part of a building used for the retail sale of goods. Roman stoae were market stalls enclosed by an arcaded walkway; stores changed little from ancient times until the latter part of the 19th century, when concentration of population and greater availability of manufactured goods gave rise to the department store, in effect a number of small specialty shops under one roof, and to the chain store and the supermarket.
With the spread of chain stores to several cities, all having the same ownership, the relationship between retailers and manufacturers changed. Direct links with factories bypassed middlemen (wholesalers) and lowered costs, in some cases forcing small independent stores to focus on narrow specialties not otherwise available. In the 1970s in the US, to coincide with the population shift out of urban centers, enclosed shopping malls of up to 250 specialty stores, anchored by at least one large department store, were constructed in many suburban areas. These “controlled shopping environments” have music, free parking, movie theaters, restaurants, and, in some instances, even child-care facilities. The idea has been adopted in the UK and elsewhere, although resistance is rising from those who wish to preserve the viability of downtown (urban center) areas.
A supply of something available for future use; SYN. stock, fund.
Layers or beds of sedimentary rock.
ETYM Latin, from sternere, stratum, to spread.
(Irregular plural: strata).
One of several parallel layers of material arranged one on top of another (such as a layer of tissue or cells in an organism).
