  "term": "Fog horizon",
  "field": "Chemistry",
  "definition": "The top of a fog layer, held down by a low-level temperature inversion, which looks like a horizon line when seen from a hillside or an aircraft. The sharp upper surface forms because the warmer air of the inversion stops the fog rising, leaving clearer air overhead. The real horizon lies behind the fog and is hidden by it.",
