Kasastus

Kasastus is a Finnish noun derived from the verb kasata, meaning to pile up or accumulate. It denotes the act of piling up, accumulation, or buildup of a substance, material, or other entities, resulting in a mass or layer. The term is used in everyday language to describe general accumulation (for example, dust, costs, cargo) and in more specialized contexts in science and engineering to refer to systematic deposition or aggregation over time.

In geology and sedimentology, kasastus can describe the process by which sediments accumulate in a basin or as a sequence of layers. In biology or ecology, it may refer to the accumulation of biomass or organic matter in an environment. In engineering or materials science, it can denote the buildup of deposits that may affect equipment performance, such as fouling or scale formation. The nuance depends on context, with kasastus implying gradual growth through successive additions rather than a single event.

Related terms include kasata (to pile up) and kasautuminen (buildup or clustering). Kasastus is a standard Finnish term, typically found in formal or technical language rather than everyday speech.
