  4. Only seismic waves
Expert · Level 87 · diurnal humidity,temperature,relative humidity
View options
  1. Temperature rises by day and falls at night
  2. Vapour disappears by day
  3. Air has no moisture at night
  4. Saturation capacity remains same day and night
Expert · Level 87 · moist air,density,molecular weight
View options
  1. At the same temperature and pressure, vapour can replace heavier molecules of dry air
  2. Vapour has no mass
  3. Moist air is always heavier than dry air
  4. Vapour exists only as solid
Expert · Level 87 · wet soil,evaporation,saturated air
View options
  1. Because air has little capacity to accept extra vapour
  2. Because wet soil has no water
  3. Because saturated air is completely dry
  4. Because evaporation needs no air condition
Expert · Level 87 · coalescence,warm cloud,rainfall
View options
  1. In warm clouds, small droplets collide and form larger drops
  2. In dry air, drops form without water
  3. All cloud droplets instantly become vapour
  4. Rainfall forms only by earthquakes
Expert · Level 87 · dew point spread,dry air,evaporation demand
View options
  1. Air is dry and evaporative demand may be high
  2. Air is fully saturated
  3. Rainfall is certain
  4. Dew formation is very likely
Expert · Level 87 · vertical distribution,water vapour,troposphere
View options
  1. Sources are near the surface and temperature is lower aloft
  2. Oceans are more common aloft
  3. Evaporation sources are greater in upper air
  4. Vapour forms only from space
Expert · Level 87 · fog dissipation,sunrise,relative humidity
View options
  1. Surface warming moves air away from saturation
  2. Air cools further and becomes more saturated
  3. The Sun converts vapour into nitrogen
  4. Visibility remains permanently zero
Expert · Level 87 · uplift,cloud formation,moisture
View options
  1. Because the process cooling air to dew point remains weak
  2. Because moisture prevents cloud formation
  3. Because uplift has no relation with condensation
  4. Because vapour turns into rock only at surface
Expert · Level 87 · cloud droplets,suspension,precipitation
View options
  1. Because they are very small and weak upward motion can support them
  2. Because they have no mass
  3. Because gravity does not act on clouds
  4. Because they instantly become solid rock

  1. (20)
  2. (15)
  3. (75)
  4. (90)
Expert · Level 87 · fog,mist,visibility
View options
  1. Because droplet concentration or effect can be greater in fog
  2. Because mist has no water droplets
  3. Because fog is always dust-free
  4. Because visibility has no relation with moisture
Expert · Level 87 · water cycle,evaporation,latent heat
View options
  1. Because water becomes vapour and carries latent heat
  2. Because only rocks are transferred
  3. Because energy has no relation with water
  4. Because no matter changes in evaporation
Expert · Level 87 · relative humidity,moisture indicator,dew point
View options
  1. Because it is a temperature-dependent percentage, not actual vapour amount
  2. Because (RH) has no calculation
  3. Because (RH) only tells air colour
  4. Because (RH) is always zero
Expert · Level 87 · condensation nuclei,cloud seed,local rainfall
View options
  1. Because vapour gets fewer bases to form droplets
  2. Because fewer particles always make more rain
  3. Because vapour does not need temperature
