Laagide

Laagide is a term used in Estonian to denote layers or strata within a material or environment. In scientific literature, it is applied to any horizontal or near-horizontal division that differs from adjacent portions in composition, texture, color, or physical properties.

In geology and sedimentology, laagide refer to beds or stratigraphic units in rock and sediment sequences. They record the history of deposition, diagenesis, and erosion, and are used to interpret past environments. Layering can arise from changes in sediment supply, climate, or tectonic conditions, and can vary in thickness from millimeters to meters.

In soil science, laagide correspond to soil horizons within a soil profile. Distinct layers such as organic-rich layers, mineral horizons, and transition zones reveal soil formation processes, drainage patterns, and fertility. The arrangement of laagide influences water movement, root penetration, and nutrient cycling.

In hydrological and atmospheric sciences, layering describes vertical stratification in water bodies and the atmosphere. In lakes and oceans, features such as thermoclines or haloclines create laagide that affect mixing and heat transfer. In the atmosphere, stratified layers separate air masses and influence weather and climate patterns.
