View options
  1. Moist maritime air and cold coastal surface
  2. Dry desert air and hot sand
  3. Ice-free surface and complete dryness
  4. Zero vapour and strong sunshine

View options
  1. Surface warming and air becoming unsaturated
  2. Water vapour always becoming solid rock
  3. Visibility disappearing by gravity
  4. Condensation nuclei changing into ocean
Hard · Level 90 · dew,surface property,cooling rate
View options
  1. Their thermal properties and cooling rates differ
  2. Each surface follows a different planetary vapour law
  3. Temperature never changes in metal
  4. Water vapour never reaches grass
Hard · Level 90 · fog,cold air,saturation capacity
View options
  1. Saturation can be reached with less moisture
  2. Cold air cannot contain any moisture
  3. Cold air always creates dry desert
  4. Cold air increases visibility without droplets
Hard · Level 90 · dew,dry air,moisture requirement
View options
  1. Enough water vapour is not available
  2. The surface is not cold
  3. Dew point is always below freezing so water cannot form
  4. The Sun is very strong at night
Hard · Level 90 · fog,cloud,ground level
View options
  1. Because both may contain suspended tiny water droplets or ice crystals
  2. Because both are only dry dust
  3. Because both have no air
  4. Because both form only below the sea
Hard · Level 90 · dew,sequence,saturation
View options
  1. Surface cooling then dew point then saturation then droplets
  2. Evaporation then dryness then earthquake then droplets
  3. Solar heating then unsaturation then frost
  4. Dust removal then zero pressure then dew
Hard · Level 90 · frost hollow,cold air drainage,frost
View options
  1. Cold dense air accumulates in low-lying areas
  2. Warm air always settles in valleys
  3. Sun never reaches valleys so there is no moisture
  4. Oxygen becomes zero in air
Hard · Level 90 · dew,frost,surface condensation
View options
  1. Because they deposit on surfaces rather than remaining suspended in air
  2. Because both form only above clouds
  3. Because neither involves water vapour
  4. Because both are ocean currents
Hard · Level 90 · fog,humidity,droplet formation
View options
  1. Because saturation, cooling, moisture, and tiny droplet conditions must combine
  2. Because humidity has no relation with water vapour
  3. Because fog forms only by earthquakes
  4. Because high humidity always causes dryness
Hard · Level 90 · radiation fog,advection fog,comparison
View options
  1. Radiation fog forms by local surface cooling and advection fog by moist air moving over a cold surface
  2. Both form only from volcanoes
  3. Radiation fog forms in sea and advection fog only in space
  4. Condensation occurs in neither
