(meteorology)
The vertical depth, measured in geometric or geopotential units, of a layer in the atmosphere bounded by surfaces of two different values of the same physical quantity, usually constant-pressure surfaces.

Thickness

 

(geology), the thickness of a stratum (vein, lens) or complex of geological deposits (suite, stage, series, system, lava sheets). A distinction is made between the true thickness (t) measured by the length of a perpendicular between the roof and floor of a stratum and the thickness visible on the earth’s surface (s). The true thickness is determined by the formula t = s sin (δ + σ), where δ is the angle of dip of the stratum and σ is the angle of inclination of the earth’s surface. The thickness of each stratigraphic subdivision varies along the strike.
