horizon

Definitions:

  • The apparent intersection of the earth and sky as seen by an observer.
  • None
  • None
  • None
  • The limit or edge of the observable universe.
  • The range of one's knowledge, experience, or interest.
  • None
  • A specific position in a column of rock layers, usually designated by the occurrence of one or more distinctive fossils or by a distinctive sediment bed, that is used in stratigraphy.
  • A layer of soil that can be distinguished from adjacent layers of soil and that is characterized by a certain color, texture, structure or chemical composition.
  • A period during which the influence of a specified culture spread rapidly over a defined area.
  • To limit or bound by a horizon.
  • The circle which at sea forms the apparent boundary between sea and sky, and on land would bound the sky were all terrestrial obstructions down to the sea-level removed. Called the <em>apparent, sensible</em>, or <em>visible horizon</em>, in distinction from the <em>astronomical horizon</em> (which see, below).
  • Hence The line that bounds the view; the limit of vision.
  • Figuratively, the limit of intellectual perception, of experience, or of knowledge.
  • In <em>geology</em>, a stratum or group of strata characterized by the presence of a particular fossil not found in the underlying or overlying beds, or of a peculiar assemblage of fossils.
  • In <em>zoology</em> and <em>anatomy</em>, a level or horizontal line or surface: as, the <em>horizon</em> of the teeth; the <em>horizon</em> of the diaphragm
  • The line which bounds that part of the earth's surface visible to a spectator from a given point; the apparent junction of the earth and sky.
  • None
  • A plane passing through the eye of the spectator and at right angles to the vertical at a given place; a plane tangent to the earth's surface at that place; called distinctively the <ex>sensible horizon</ex>.
  • A plane parallel to the sensible horizon of a place, and passing through the earth's center; -- called also <altname>rational horizon</altname> or <altname>celestial horizon</altname>.
  • The unbroken line separating sky and water, as seen by an eye at a given elevation, no land being visible.
  • The epoch or time during which a deposit was made.
  • The chief horizontal line in a picture of any sort, which determines in the picture the height of the eye of the spectator; in an extended landscape, the representation of the natural horizon corresponds with this line.
  • The limit of a person's range of perception, capabilities, or experience.
  • A boundary point or line, or a time point, beyond which new knowledge or experiences may be found.
  • See under <er>Apparent</er>.
  • a level mirror, as the surface of mercury in a shallow vessel, or a plane reflector adjusted to the true level artificially; -- used chiefly with the sextant for observing the double altitude of a celestial body.
  • See def. 2, above.
  • the vertical angle between the sensible horizon and a line to the visible horizon, the latter always being below the former.
  • See def. 2, above.
  • None
  • See definitions 1 and 2, above.
  • The <xref>horizontal</xref> line that appears to <xref>separate</xref> the <xref>Earth</xref> from the <xref>sky</xref>.
  • The <xref>range</xref> or <xref>limit</xref> of one's <xref>knowledge</xref>, <xref>experience</xref> or <xref>interest</xref>.
  • A specific <xref>layer</xref> of <xref>soil</xref> or <xref>strata</xref>
  • A cultural sub-period or level within a more encompassing time period.
  • a specific layer or stratum of soil or subsoil in a vertical cross section of land
  • the great circle on the celestial sphere whose plane passes through the sensible horizon and the center of the Earth
  • the line at which the sky and Earth appear to meet
  • the range of interest or activity that can be anticipated
