View options
  1. Because both heat and broad water surface are available there
  2. Because oceans prevent evaporation
  3. Because there is no air in the tropics
  4. Because seawater is completely solid
Expert · Level 86 · molecular evaporation,cooling,latent heat
View options
  1. The remaining surface may become relatively cooler
  2. The remaining surface necessarily starts boiling

View options
  1. Saturation is not a sufficient condition for rainfall
  2. There is no water vapour in air
  3. Condensation never occurred
  4. Temperature has no importance
Expert · Level 86 · contact cooling,fog,condensation sequence
View options
  1. Contact cooling then dew point then condensation
  2. Evaporation then dryness then frost
  3. Boiling then rainfall then dry air
  4. Zero pressure then cloud
Expert · Level 86 · absolute humidity,relative humidity,definitions
View options
  1. Relative humidity gives ratio to capacity while absolute humidity gives actual amount
  2. Both tell only wind direction
  3. Both are same as rainfall
  4. Absolute humidity is always 100 percent

View options
  1. Evaporation will slow down
  2. Evaporation will necessarily become maximum
  3. Water will immediately boil
  4. Condensation nuclei will disappear
Expert · Level 86 · orographic cloud,moisture,dew point
View options
  1. Even on reaching dew point there will be little condensable vapour
  2. Rising air never cools
  3. Mountains destroy all condensation nuclei
  4. Low moisture always gives heavy rainfall
Expert · Level 86 · evaporation factors,temperature,wind humidity
View options
  1. Higher temperature increases energy availability but humidity and wind also affect it
