View options
  1. It will generally decrease
  2. It will always be (100%)
  3. It will be below zero
  4. Water vapour will disappear
Expert · Level 87 · vapour pressure gradient,evaporation,near surface humidity
View options
  1. Because the vapour pressure gradient decreases
  2. Because vapour instantly becomes oxygen
  3. Because surface area becomes zero
  4. Because water temperature becomes infinite
Expert · Level 87 · dew,cloudy night,longwave radiation
View options
  1. Clouds reduce surface cooling by trapping longwave radiation
  2. Clouds completely dry the surface
  3. Clouds remove all vapour
  4. Clouds always make dew point zero
Expert · Level 87 · humidity,sweat evaporation,body cooling,heat index,atmospheric moisture
View options
  1. Because reduced evaporation of sweat decreases body cooling
  2. Because humid air increases heat production inside the body
  3. Because the amount of oxygen in humid air becomes zero
  4. Because water vapour changes into ice particles in warm humid air
Expert · Level 87 · temperature inversion,pollution,fog
View options
  1. Because vertical mixing is weak and particles act as condensation nuclei
  2. Because inversion makes air completely dry
  3. Because pollution destroys vapour
  4. Because fog persists only with strong mixing

View options
  1. Bergeron process
  2. Only evaporation process
  3. Permanent dryness process
  4. Salinity process
Expert · Level 87 · dew point,temperature,actual moisture
View options
  1. Air is warming and actual moisture may also be increasing
  2. Air is definitely becoming completely dry
  3. Relative humidity will always become (100%)
  4. Condensation will stop in every case
Expert · Level 87 · water vapour,local climate,radiation
View options
  1. Because water vapour is linked with radiation, clouds, and rainfall processes
  2. Because vapour is the main solid material of Earth
  3. Because vapour has no relation with energy
  4. Because vapour exists only in rocks
Expert · Level 87 · saturation,condensation,deposition
View options
  1. It may condense or deposit
  2. It always becomes nitrogen
  3. It removes gravity
  4. It permanently dries the ocean

View options
  1. Evaporation rate may decrease
  2. Evaporation will become infinite
  3. The lake will freeze instantly
  4. Vapour in air will be zero
Expert · Level 87 · condensation nuclei,cooling,cloud formation
View options
  1. When condensation nuclei are very scarce
  2. When vapour is available in air
  3. When the surface is cold
  4. When (RH) is increasing
Expert · Level 87 · vapour pressure,partial pressure,humidity
View options
  1. Because it is the pressure exerted only by water vapour in the air mixture
  2. Because it applies only on mountains
  3. Because it is greater than total air pressure
  4. Because it measures sound in air
Expert · Level 87 · maritime air,convection,condensation
View options
  1. Because moisture, heat, and uplift together enhance condensation
  2. Because maritime air has no vapour
  3. Because warm land pushes air downward
  4. Because uplift prevents condensation
