Practice questions
If evaporation is rapid and air is continuously removed, why can surface cooling increase?What may happen when strong daytime evaporation occurs over a warm lake and cooler air arrives in the evening?In which condition is evaporation most likely to be maximum?Dew on leaves in the morning and its disappearance by afternoon shows which sequence?Why are tropical oceans a major source of atmospheric water vapour?Which condition is most necessary for frost formation on clear winter nights?If water vapour increases while temperature remains constant, why does relative humidity rise?Why can humidity gradually increase if an open bucket of water is kept in a closed room?What is the correct reason for water droplets forming outside a cold bottle?Why can high humidity increase crop diseases in agricultural areas?Why is water vapour alone not always enough for cloud formation?Why can rising moist air produce more weather change than rising dry air?In which condition can relative humidity approach 100 percent without rainfall?If air temperature falls while vapour amount does not change, what happens in relation to dew point?Why do clothes take longer to dry on a day with high relative humidity?How can pollution particles help fog formation in urban areas during morning?When evaporation occurs from salty seawater, what mainly enters the atmosphere?Why can a small amount of vapour in cold air still give high relative humidity?What is the basic similarity between dew and fog?If air temperature and dew point temperature become nearly equal, what will be the atmospheric condition?
