Horizontal vs. Horizon — What's the Difference?

Of, relating to, or near the horizon.

The horizon is the apparent line that separates the surface of a celestial body from its sky when viewed from the perspective of an observer on or near the surface of the relevant body. This line divides all viewing directions based on whether it intersects the relevant body's surface or not.

Parallel to or in the plane of the horizon.

The apparent intersection of the earth and sky as seen by an observer. Also called apparent horizon.

At right angles to a vertical line.

See sensible horizon.

Occupying or restricted to the same level in a hierarchy

See celestial horizon.

(Medicine) Of or relating to transmission of infection by contact with or physical proximity to an infected individual or fomite.

The limit or edge of the observable universe.

Something, such as a line, plane, or object, that is horizontal.

The range of one's knowledge, experience, or interest.

Perpendicular to the vertical; parallel to the plane of the horizon; level, flat.

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.

(marketing) Relating to horizontal markets

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.

(archaic) Pertaining to the horizon.

(Archaeology) A period during which the influence of a specified culture spread rapidly over a defined area

(wine) Involving wines of the same vintages but from different wineries.

The visible horizontal line (in all directions) where the sky appears to meet the earth in the distance.

Having the two notes sound successively.

(figuratively) The range or limit of one's knowledge, experience or interest; a boundary or threshold.

Relating to sexual intercourse.

The range or limit of any dimension in which one exists.

A horizontal component of a structure.

(geology) A specific layer of soil, or stratum

(geology) Horizon.

A cultural sub-period or level within a more encompassing time period.

A Tasmanian shrub or small tree whose main trunk tends to lean over and grow horizontally, Anodopetalum biglandulosum

Any level line or surface.

Pertaining to, or near, the horizon.

(chess) The point at which a computer chess algorithm stops searching for further moves.

Parallel to the horizon; on a level; as, a horizontalline or surface.

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.

Measured or contained in a plane of the horizon; as, horizontal distance.

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 sensible horizon.

Something that is oriented horizontally

The epoch or time during which a deposit was made.

Parallel to or in the plane of the horizon or a base line;

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; as, children raised in the inner city have limited horizons.

A boundary point or line, or a time point, beyond which new knowledge or experiences may be found; as, more powerful computers are just over the horizon.

The line at which the sky and Earth appear to meet

The range of interest or activity that can be anticipated;

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
