Naturalists formerly divided the sea-bottom into five zones in accordance with the depth of water covering each, which was supposed to determine its fauna and flora. They were called respectively littoral, circumlittoral, median, inframedian, and abyssal. Later researches have proved that the assumed facts were to a great extent erroneous, organisms supposed to be confined to the littoral zone having been found at the greatest depths. In geology zone has nearly the same meaning as horizon. A stratum, or a group of strata, may be characterized by the presence of a certain assemblage of fossils, or by one particular fossil; in such cases the most abundant or typical fossil may give a name to the subdivision in which it occurs, which will then be designated as the zone of that particular species. Thns, the Lower and the Middle Lias have together been divided into twelve zones, each characterized by the presence of a certain species of ammonite: as, the “zone of the Arietites (Ammonites) raricostatus,” etc.

Comfort zone - It is the temperature range in which the body doesn't shiver or sweat, but has an idiomatic sense of a place where people feel comfortable, where they can avoid the worries of the world. It can be physical or mental.
In the zone - If you are in the zone, you are very focused on what you have to do.

These excluded zones should not be considered a real effect; slight changes in model parameters can move these zones around without changing the overall model conclusions, and increased sampling of the core mass function beyond three masses (0.3, 1, and 3 M⊙ ) are likely to fill in at least some of them.
