How is fog formed?
Water vapor is always around us in the atmosphere, in varying amounts according to pressure and temperature. When the temperature drops suddenly, these water vapor particles condense on the dust specks in the air, and this produces the haze we call ‘fog’.
‘Smog’ is a combination of smoke and fog. And is a particular menace in the industrial cities of America, but surprisingly it is Athens in Greece which suffers badly from smog. Smog eats away at the classical Greek building there, such as the Parthenon, at an amazing rate, causing serious damage.

What is trivia? the word has an origin with two Latin roots: tri meaning three and via meaning roads.
Trivia refers to a place near Rome where three roads met and people gathered to talk about things of little consequence. Thus the modern day "trivia".
