felületközeli

Felületközeli is a Hungarian term that translates to "near-surface" or "surface-level" in English. It is used in various contexts to describe phenomena, processes, or objects that are located in close proximity to a surface, rather than being deep within a material or far from it.

In geology and soil science, "felületközeli" refers to the uppermost layers of the Earth's crust or soil. This can include processes like weathering, erosion, or the distribution of organic matter, which primarily occur at or near the surface. The properties and composition of these near-surface layers are crucial for understanding ecological systems, agriculture, and land management.

In physics and engineering, the term can describe phenomena occurring at the boundary of two materials. For example, in solid-state physics, "felületközeli" states or effects are those that are localized within a few atomic layers of a material's surface. This is important in understanding surface catalysis, thin-film behavior, and electronic device performance.

The concept also extends to other fields. In fluid dynamics, "felületközeli" flows might describe currents or behaviors that are concentrated near the interface between a fluid and a solid or another fluid. In a more general sense, it can simply indicate something that is not internal or deep, but rather on or very close to the exposed outer layer of an object or system.
