straturi

Straturi is the Romanian noun that denotes layers or levels—objects, materials, or concepts arranged in a vertical sequence or in a hierarchical order. The word comes from Latin stratum, meaning “bed” or “layer.” It is used across scientific, technical, and everyday contexts to describe a stacked or layered structure.

In geology and stratigraphy, straturi geologice are the successive beds of rock or sediment that record past environments. Stratigraphy studies these layers to understand Earth’s history, using principles such as superposition, correlation, and lithology. Fossil content and radiometric dating within strata help establish relative and absolute ages.

In soils and ecology, straturi refer to soil horizons. Common horizons are O, A, E, B, and C, reflecting organic matter accumulation, leaching, and weathering processes. The arrangement of these layers influences water movement, nutrient availability, and plant growth.

In the atmosphere and biology, straturi describe concentric or functional layers, such as atmospheric strata (troposferă, stratosferă) or tissue layers in organisms (epidermis, dermis). In technology, straturi denote layers within computer architectures, neural networks, and data-processing pipelines, where each layer performs distinct functions.

The concept of layering also appears in everyday life and culture, with foods, fabrics, and constructions described by their component strata, emphasizing how combining layers creates a composite whole.
