One of the most imitated scenes in movie history. On the Waterfront is the movie that finally won Marlon Brando a Best Actor Academy Award. I say finally because it was his 4th consecutive nomination. In 1951 he was nominated for A Streetcar Named Desire but lost to Humphrey Bogart in The African Queen.
Basically, fog forms when warm air meets colder air. When this happens, water vapor in the air â a gas â is cooled enough for the gas to turn to a liquid in the form of tiny water droplets. This process is called condensation.. We see those groups of tiny droplets as clouds or, when they're close to the ground, as fog.
Condensation results mainly from the cold air mixing with the air that is in contact with the water surface. However, convection also occurs, because the water is so much warmer than the overlying air. This convection causes the mixed air to rise a metre or more, thus enhancing the process of fog formation. Because of the convection, the water appears to âsteamâ. The photo shown was taken in the Canadian province of Quebec.
