A foundation is the lowest and supporting layer of a structure.

The gorge is littered with blocks of the middle sandstone that broke off as the supporting layer below wore away.

The other aim is to create separate, mutually supporting layers of defense so that a target that slips past one can be attacked by another.

A canopied bed dominated the room, its four stout carved posts supporting layers of sheer drapes, the material hanging in loose folds.

The latter can be demonstrated with special staining techniques (immunohistochemistry for cytokeratins) to identify the basal cells forming the supporting layer of the acinus.

Between ectoderm and endoderm is a supporting layer of structureless gelatinous substance termed mesogloea, secreted by the cell layers of the body wall.

The photographic emulsion used for color photographic materials consists of three color emulsion layers (cyan, yellow, and magenta) along with other supporting layers.

Effused or resupinate fruiting bodies typically consist of two layers - tube layer of vertically arranged tubes that open downwards, and supporting layer called subiculum that supports and attached the tubes to substrate.
