Lapisanlapisan

Lapisan-lapisan is an Indonesian term that describes multiple layers or strata arranged in a vertical sequence. The form combines lapisan (layer) with reduplication to indicate plurality or repetition of layers. It is used across disciplines to refer to structures characterized by stacking, from natural deposits to engineered materials.

In geology and soil science, lapisan-lapisan denotes stratified deposits and soil horizons. Sedimentary rocks accumulate in successive layers called beds, each recording the conditions at the time of deposition. Soils develop horizons with distinct color, texture, and mineral composition, reflecting processes of weathering, leaching, and organic matter input.

In biology, layered organization appears in tissues and epithelia, where cells are arranged in strips or strata. The concept also appears in anatomy and developmental biology when describing hierarchical tissue architecture.

In atmospheric and environmental contexts, the atmosphere and other media are described as layered, with properties that vary with altitude or depth, such as the troposphere and stratosphere.

In engineering and materials science, lapisan-lapisan refers to laminated or stratified structures where different layers contribute to strength, insulation, or other function. Recognizing layering aids interpretation of history, performance, and design.
