Horizon vs. Sunset: What's the Difference?

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

The event or time of the disappearance of the upper circumferential edge of the sun as it sets below the horizon.

See sensible horizon.

The sky as the sun sets

See celestial horizon.

A decline or final phase

The limit or edge of the observable universe.

(Law) The automatic expiration of a statutory provision on a previously established date, in the absence of reauthorization

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

(Law) Providing for an automatic expiration.

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.

To expire on a previously established date, as a statutory provision.

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.

To provide for the expiration of (a program or agency) by means of a sunset provision.

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

The moment each evening when the sun disappears below the western horizon.

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

The changes in color of the sky before and after sunset.

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

(figuratively) The final period of the life of a person or thing.

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

(attributively) A set termination date.

(geology) A specific layer of soil, or stratum

The region where the sun sets; the west.

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

To phase out.

Any level line or surface.

The descent of the sun below the horizon; also, the time when the sun sets; evening. Also used figuratively.

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

Hence, the region where the sun sets; the west.

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.

The time in the evening at which the sun begins to fall below the horizon

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.

Atmospheric phenomena accompanying the daily disappearance of the sun

The epoch or time during which a deposit was made.

The daily event of the sun sinking below the horizon

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.

Of a declining industry or technology;

The limit of a person's range of perception, capabilities, or experience; as, children raised in the inner city have limited horizons.

Providing for termination;

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
