Forms of condensation: dew, frost, fog, and mist
Practice questions
If a desert night is very cold but the air is extremely dry, why will dew formation be limited?Why may a steam-like mist appear over a lake on a cold morning?Which statement is most helpful in identifying frost?Why can wind speed help disperse fog?What may happen if temperature falls below freezing after dew has formed?In which condition is dew more likely than fog?Why does visibility reduce in fog even though droplets are tiny?Which classification is correct on the basis of surface condensation and lower-air condensation?If on a clear night the surface cools to dew point but remains above freezing point which form is most likely?If water vapour directly deposits as ice crystals on a very cold surface which form does it explain?Why can fog persist longer in a valley during temperature inversion?Which meteorological criterion is most useful to distinguish mist from fog?What is the most correct role of clear sky in dew formation?If the night is clear but wind is very strong why can dew formation decrease?What is the main mechanism of fog formation when warm moist air moves over cold land?Which combined effect works when steam-like mist forms over a warm lake under cold air?What can be the role of tiny dust and smoke particles in urban fog?Dew and frost may have the same water vapour source yet why are their final forms different?If fog is dense only over a river and not on nearby land what is the most suitable reason?What is the most accurate physical reason for very low visibility in dense fog?
