Which term has a primary implication of 'Geological layer, composition, hazard'?

Answer

Lunar Regolith

The term Lunar Regolith carries the highest level of specificity and technical implication, signifying not just the appearance of loose material but its status as a defined geological layer whose composition and known physical characteristics, including inherent hazards, are documented. This designation is authoritative in scientific research, engineering design, and mission planning because it immediately flags the material's known properties. In contrast, 'Moondust' implies only visual appearance, and 'Fine Powder' only the texture.
