Latin = a covering sheet, or layer.
Layer of sedimentary rock compromised of one rock type. Layers of strata containing different rocks may form parallel bands of different rock. Strata is the plural form of stratum.
L. = layer, bed-covering, sheet; of layers in the skin: cf. basale, spinosum, germinativum, granulosum; lucidum, corneum; rete Malpighii.
pl. strata: A layer within the earth's crust that generally consists of the same kinds of soils or rock material.
(STRA·tum), plural, strata. Subdivision of the period, based on stratigraphic evidence of a major cultural break, connected with a series of loci or layers, and supported by ceramic, architectural, and object data. Often radical changes, such as destruction layers, mark a stratum at its beginning and end.
an abstract place usually conceived as having depth; "a good actor communicates on several levels"; "a simile has at least two layers of meaning"; "the mind functions on many strata simultaneously"
a sedimentary unit included between two boundary gbc surfaces
(pl. strata) A subpopulation, usually referring to the collection of all those individuals sharing some characteristic.
organizational layers in a managerial hierarchy. The work in a given stratum is characterized by a specific range of complexity.
A single bed of sedimentary rock, generally consisting of one kind of matter representing continuous deposition.
A layer in a community produced by the occurrence at approximately the same level of an aggregation of plants of the same habit. Beadle and Costin, 1952; NVIS
A layer or horizon of sedimentary rock.
A sedimentary bed or layer that generally consists of the same kind of soils or rock material.
a layer of earth that is distinct and discrete from those above or below.
(plural strata) • A layer or sedimentary rock laid down at a particular time in a past.
pl. strata. - layer of material, in this case formed naturally; often one of a number of parallel layers, placed one upon another..
A layer of rock or soil, of the same composition, distinguishable (but not necessarily of different composition) from surrounding layers. Lower stratum are geologically older than those above (except in rare cases). This is referred to as the Law of Superposition.
A layer of material deposited by cultural or geological processes.
A tabular or sheet-like mass, or a single, distinct layer of material of any thickness, separable from other layers above and below by a discrete change in character of the material or by a sharp physical break, or by both. The term is generally applied to sedimentary rocks, but could be applied to any tabular body of rock. (see also Bed)
One of a series of layers or levels in an ordered system.
Divisions of a field that enhance sampling designs. For representative sampling, each field may be divided into four or more strata.
A layer of rock (plural strata).
A bed or layer of sediment.
(The plural is strata.) A single depositional layer, usually seen as part of more complex stratigraphy consisting of several strata.
In geology and related fields, a stratum (plural: strata) is a layer of rock or soil with internally consistent characteristics that distinguishes it from contiguous layers. Each layer is generally one of a number of parallel layers that lie one upon another, laid down by natural forces. They may extend over hundreds of thousands of square kilometers of the Earth's surface.
