Task: Class Definition Understanding (ontology: Earth_Environment/SWEET)

Which of the following definitions best describes 'haze'?

A. A fog the droplets of which freeze upon contact with exposed objects and form a coating of rime and/or glaze.
B. Particles suspended, reducing visibility by scattering light; often a mixture of aerosols and photochemical smog.
C. Fog associated with frontal zones and frontal passages. It is usually divided into three types: warm-front prefrontal fog; cold-front post-the concept; and frontal-passage fog. The first two types are a result of rain falling into cold stable air and raising the dewpoint temperature. Frontal-passage fog can result from the ?mixing of warm and cold air masses in the frontal zone? or by ?sudden cooling of air over moist ground.?
D. Fog formed as a result of evaporation of water that is warmer than the air.

Answer: Particles suspended, reducing visibility by scattering light; often a mixture of aerosols and photochemical smog.
