zone

Definitions:

  • None
  • An area or a region distinguished from adjacent parts by a distinctive feature or characteristic.
  • A section of an area or territory established for a specific purpose, as a section of a city restricted to a particular type of building, enterprise, or activity.
  • An area of a given radius within which a uniform rate is charged, as for transportation or shipping.
  • None
  • Any of the five regions of the surface of the earth that are loosely divided according to prevailing climate and latitude, including the Torrid Zone, the North and South Temperate Zones, and the North and South Frigid Zones.
  • A similar division on any other planet.
  • A portion of a sphere bounded by the intersections of two parallel planes with the sphere.
  • An area characterized by distinct physical conditions and supporting a particular type of flora and fauna.
  • A ringlike or cylindrical growth or structure.
  • A region or stratum distinguished by composition or content.
  • A zone defense.
  • A belt or girdle.
  • To divide or designate into zones.
  • To surround or encircle.
  • To focus or concentrate on something.
  • To lose concentration or become inattentive.
  • (<em>in the zone</em>) In a state of focused attention or energy so that one's performance is enhanced.
  • To encircle with or as if with a zone; bring within a zone, or divide into zones or belts, in any sense.
  • To be formed into zones.
  • A girdle or belt worn as an article of dress.
  • A belt or band round anything, as a stripe of different color or substance round an object; figuratively, any circumscribing or surrounding line, real or imaginary; a circuitous line, path, or course; an inclosing circle.
  • Specifically, in <em>geography</em>, one of five arbitrary divisions of the earth's surface, bounded by lines parallel to the equator, each named according to its prevailing temperature; a climatic belt.
  • Any continuous tract or belt differing in character from adjoining tracts; a definite area or region within which some distinguishing circumstances exist or are established: as, the <em>zones</em> of natural history, distinguished by special forms of vegetable or animal life; a <em>zone</em> of free trade; a free <em>zone</em> on the border of a country or between adjoining states.
  • In <em>mathematics</em>, a part of the surface of a sphere included between two parallel planes.
  • In <em>crystallography</em>, a series of planes having their lines of intersection parallel.
  • A portion of the surface of a sphere cut off by one plane.
  • A belt on the surface of the earth or of the celestial sphere included between two parallels to the equator.
  • In <em>phytogeography</em>, a vegetation ring or belt: referring more directly to the plant-content itself or to the areas marked by œcological difference.
  • One of the different levels of a shaft-furnace, characterized according to the reaction which takes place in it: as, the <em>zone</em> of fusion, reduction-<em>zone</em>, etc.
  • Transition climate, in which the variation is greater than 15° C. and less than 20° C.
  • Land climate, in which the variation is greater than 20° C. and less than 40° C.
  • Extreme continental climate in which the variations are greater than 40° C. <em>Koeppen's climatic zones</em> are arbitrary divisions based upon temperature considerations as follows: A tropical zone having an average temperature of over 68° F.
  • A subtropical zone which has the same temperature during 4 to 11 months.
  • A constant temperate zone with a temperature between 50 and 68° F.
  • A hot summer temperate zone which has an average temperature that sometimes falls below 50° F.
  • A moderate summer and cold winter temperate zone with a temperature between 50 and 68° F.
  • A cold zone with a prevailing temperature below 50° F.
  • A polar zone with an average temperature always below 50° F. <em>Wojeikoff's climatic zones</em> are distinguished according to the quantity and character of the rainfall. Twelve climatic regions are shown upon his maps as follows: A zone of ocean trades with very rare rainfalls.
  • A region of equatorial rains, including the zone of calms.
  • A region of rain which prevails throughout the year.
  • A subtropical zone with rainless summers.
  • A zone of the fall and winter rains of middle latitudes.
  • The zone of summer rainfall of middle latitudes.
  • The zone of equal distribution of rain throughout all seasons.
  • A polar region with light snows in winter.
  • Deserts and semi-deserts with an annual precipitation less than 250 mm. (10 in.).
  • (10) The region of the Australian monsoons.
  • (11) The region of the Asiatic monsoons.
  • (12) The region of the African monsoons. Climatic zones in altitude correspond to climatic zones in latitude and are marked by the retardation of the dates of the development of vegetation; this retardation amounts to about ten days for every 300 meters of increase in altitude in the Alps, or four days for 800 meters in France.
