Hard · Level 86 · saturation,cooling,moisture addition
View options
  1. Decreasing temperature or increasing water vapour content
  2. Increasing river length or removing mountains
  3. Changing land colour or melting rocks
  4. Increasing sound in air or shortening the day
Hard · Level 86 · water cycle,evaporation,condensation
View options
  1. Evaporation sends water to the atmosphere and condensation turns it into cloud droplets
  2. Both only keep groundwater fixed
  3. Neither has any relation with water vapour
  4. Both only form mountains
Hard · Level 87 · humidity,relative humidity,temperature
View options
  1. It will decrease because warm air has higher moisture-holding capacity
  2. It will increase because temperature directly adds water vapour
  3. It will always become 100 percent
  4. It will remain unchanged because vapour amount is same
Hard · Level 87 · dew point,condensation,saturation
View options
  1. Because air approaches saturation
  2. Because water vapour completely disappears
  3. Because air pressure becomes zero
  4. Because evaporation becomes impossible
Hard · Level 87 · desert air,relative humidity,evaporation
View options
  1. Air has high moisture-holding capacity but actual vapour is low
  2. Sand directly turns vapour into clouds
  3. High temperature always causes condensation
  4. Evaporation never occurs in deserts
Hard · Level 87 · coastal humidity,evaporation,saturation
View options
  1. Because the air already contains high water vapour
  2. Because sea air has no water vapour
  3. Because salt makes relative humidity zero
  4. Because temperature never changes at coasts
Hard · Level 87 · relative humidity,evaporation rate,saturation
View options
  1. Because air is very close to saturation
  2. Because air has no water vapour
  3. Because the Sun gives no energy
  4. Because boiling point of water decreases
Hard · Level 87 · wind speed,evaporation,humidity
View options
  1. Wind removes the moist layer near the surface and increases evaporation
  2. Wind immediately turns water into ice
  3. Wind always makes relative humidity 100 percent
  4. Wind destroys condensation nuclei
Hard · Level 87 · dew,dew point,valley cooling
View options
  1. Because cool dense air collects in valleys and may reach dew point
  2. Because the Sun heats valleys more at night
  3. Because water vapour is always absent in valleys
  4. Because lower altitude makes condensation impossible
Hard · Level 87 · relative humidity,formula,vapour pressure
View options
  1. Saturation vapour pressure
  2. Actual wind speed
  3. Permanent rainfall amount
  4. Ocean salinity
Hard · Level 87 · condensation,dew,fog
View options
  1. When vapour condenses as dew or fog on a surface or in air
  2. When air is completely dry
  3. When temperature is above boiling point of water
  4. When there are no dust particles in air
Hard · Level 87 · saturated air,cooling,condensation
View options
  1. Extra water vapour begins to condense
  2. It can remain in air in infinite amount
  3. It changes into oxygen
  4. It removes air pressure
Hard · Level 87 · transpiration,humidity,forest microclimate
View options
  1. Because transpiration adds water vapour to air
  2. Because trees destroy atmospheric vapour
  3. Because forests always have zero temperature
  4. Because leaves eliminate air pressure
Hard · Level 87 · fog,mist,dew point
View options
  1. Because the air cools to its dew point
  2. Because the cold surface heats the vapour
  3. Because moisture in air falls to zero
  4. Because sea waves make clouds
Hard · Level 87 · absolute humidity,relative humidity,weather comfort
View options
  1. Because it shows nearness to saturation according to temperature
  2. Because it shows only wind direction
  3. Because it is total annual rainfall
  4. Because it measures ocean depth
Hard · Level 87 · humidity,sweat,evaporation
View options
  1. High relative humidity slows evaporation
  2. High temperature turns sweat into stone
  3. Humid air has no water vapour
  4. Solar energy stops evaporation
Hard · Level 87 · temperature,relative humidity,saturation capacity
View options
  1. Because cooler air has lower saturation capacity
