How does *lunar regolith* differ from 'moondust' in conveying information?
Answer
It implies known physical characteristics and location over bedrock.
The term lunar regolith is authoritative because it conveys precise, actionable information: it locates the material as the specific outermost layer covering the bedrock and implies a known set of physical characteristics, such as its abrasive quality, chemical makeup, and particle size distribution. While 'moondust' offers a simple visual connection, 'lunar regolith' immediately signals that the discussion requires technical understanding relevant to spacecraft design, life support, and hazard mitigation, reflecting a move from casual description to technical classification.
