Skikt

Skikt is a Swedish noun meaning layer, tier, or stratum. In scientific and technical Swedish, skikt denotes a distinct horizontal or near-horizontal division within a material, substance, or environment. The term is used across disciplines to describe how properties vary with depth, height, or position.

In geology and sedimentology, a skikt refers to a layer within rock or sediment with relatively uniform characteristics, such as grain size, mineral composition, color, or cementation. Sequences of skikt form stratigraphic units that record depositional history and geological events.

In soil science, soil profiles are described in terms of horizons or skikt. Individual skikt reflect processes such as organic matter accumulation, leaching, and mineral weathering, producing typical sequences such as organic horizons and mineral A-, E-, and B-horizons.

In atmospheric science, the atmosphere is described as consisting of sequential skikt such as the troposphere and stratosphere, each associated with characteristic temperature gradients, chemical composition, and weather or climate behavior.

In materials science and engineering, skikt denote layers in composites, coatings, multilayer films, or laminated structures. The arrangement and thickness of these skikt determine properties such as strength, thermal conductivity, and optical performance.
