Geography
Forms of condensation: dew, frost, fog, and mist
Practice questions
If the night is calm and clear but air is very dry why will dew formation be low?Why is frost considered more dangerous for crops than dew?Why is cooling of air to dew point necessary for fog formation?If mist disappears as the day advances what is the most likely reason?What is the most correct location-based difference between dew and fog?What is the correct description of the role of dust particles in fog formation?If air is saturated but the ground is warm what condition may be lacking for fog formation?When can surface being colder than air temperature be important in dew formation?What is the common initial requirement for both frost and dew formation?If droplets form on a cold surface and freeze immediately it is most closely related to what?Formation of fog and its later lifting is most related to which daily change?Why is it wrong to call mist only water vapour?In which situation is frost formation least likely?Why do droplets in fog and mist generally not fall to the ground?If dew on leaves disappears soon after sunrise what is the process sequence?Why is the lower air layer important in fog formation?Why can a cloudless cold night help frost formation?If moisture is sufficient but air mixes and moves away from the surface instead of staying near it what happens to dew?Why does water vapour change from invisible gas to visible droplets during fog formation?Why can mist be seen more near open water bodies in the morning?
