Forms of condensation: dew, frost, fog, and mist
Practice questions
If there is dew in a field in the morning but visibility is normal, which conclusion is correct?White frost after a clear calm winter night is the result of which combined condition?If on a clear night grass temperature falls below dew point but remains above freezing point which form is most appropriate?If surface temperature is below freezing and water vapour directly deposits as ice crystals what will be the result?Why is it most correct to call fog a cloud near the ground?Which statement correctly explains the visibility-based difference between mist and fog?What is the main reason for less dew formation on a cloudy night?How can strong wind affect dew formation?What may cause fog to persist more in a valley during morning?If warm moist air flows over a cold land surface which type of fog may form?Why can fog form when relatively warm moist air moves over cold water?Why can steam-like mist appear when cold air moves over a warm lake?How can urban pollution particles help make fog denser?Why can fog remain for longer during a temperature inversion?If field leaves have white crystals instead of liquid droplets what is the correct identification?What mainly decides whether dew or frost forms?What is the main process-related difference between fog and rainfall?What is the physical explanation for low visibility in dense fog?If both fog and mist form from tiny droplets why are they differentiated?Why can frost form more easily in an open field?
