  2. Condensation during day and evaporation at night
  3. Only rainfall and snowfall
  4. Only air pressure change
Hard · Level 87 · tropical ocean,evaporation,water vapour
View options
  1. Because both heat and water surface are highly available there
  2. Because air there contains no moisture
  3. Because oceans prevent evaporation
  4. Because the equator receives no solar energy
Hard · Level 87 · frost,condensation,freezing surface
View options
  1. Surface temperature below freezing and air reaching a very low dew point
  2. Very high surface temperature and dry air
  3. Strong hot wind and low radiational cooling
  4. Only presence of sea waves
Hard · Level 87 · water vapour,relative humidity,saturation
View options
  1. Because air moves closer to its saturation limit
  2. Because saturation limit suddenly becomes infinite
  3. Because moisture has no effect at constant temperature
  4. Because vapour makes air pressure zero
Hard · Level 87 · indoor humidity,evaporation,water surface
View options
  1. Because evaporation adds water vapour to room air
  2. Because water pulls oxygen from air
  3. Because a closed room makes temperature zero
  4. Because vapour cannot leave so rainfall occurs immediately
Hard · Level 87 · condensation,cold surface,dew point
View options
  1. Moist outside air cools and condenses on the bottle surface
  2. Water inside the bottle leaks through glass
  3. The bottle changes oxygen into water
  4. The cold bottle makes air completely dry
Hard · Level 87 · agriculture,humidity,condensation
View options
  1. Because moisture persists on surfaces and supports fungal growth
  2. Because high humidity turns soil into stone
  3. Because vapour eliminates sunlight
  4. Because humidity makes plant water zero
Hard · Level 87 · cloud formation,condensation nuclei,saturation
View options
  1. Because saturation, cooling and condensation nuclei may also be needed
  2. Because vapour does not participate in cloud formation
  3. Because clouds are only smoke
  4. Because clouds always form without air
Hard · Level 87 · moist air,latent heat,condensation
View options
  1. Because cooling can cause condensation and release latent heat
  2. Because moist air has no energy
  3. Because dry air always produces rainfall
