Forms of condensation: dew, frost, fog, and mist

Question 1ExpertLevel 90

If frost warning is given which process does a farmer try to reduce by covering crops?

AExcessive radiational heat loss from surfaceBSoil salinityCRiver erosionDSea tide

Question 2ExpertLevel 90

What is the main exam-worthy difference between frost and snowfall?

ABoth are completely identicalBFrost deposits on surface while snowfall falls from cloudsCFrost forms below sea floorDSnowfall is unrelated to water vapour

Question 3ExpertLevel 90

If fog begins to clear as the day advances what is the most likely reason?

AAir becoming stoneBPermanent disappearance of water vapourCLower air warms and evaporates dropletsDSun becoming cold

Question 4ExpertLevel 90

If no droplets are present on the surface but the air is hazy which clue is strongest?

APresence of tiny droplets suspended in airBFrost on surfaceCDew on surfaceDSalinity in soil

Question 5ExpertLevel 90

If air is near saturation but the lower air layer is continuously mixing what may happen to fog formation?

AFog will necessarily become denseBFog formation may be hinderedCFrost will necessarily formDWater vapour will disappear

Question 6ExpertLevel 90

If mist seems to gradually turn into dense fog which change is most likely?

AAir is becoming completely dryBWater vapour is disappearingCDroplet concentration is increasing and visibility is decreasingDSurface is becoming lava

Question 7ExpertLevel 90

If very cold but very dry air blows over a field what will be the biggest limitation for frost formation?

AExistence of surfaceBNight timeCCold temperatureDAvailability of water vapour

Question 8ExpertLevel 90

Why can dew droplets dry quickly after strong wind begins?

AWind removes moist layer near surface and increases evaporationBWind turns droplets into rockCWind removes the SunDWind makes air pressure zero

Question 9ExpertLevel 90

If a surface does not reach dew point though air has moisture why will dew not form?

AMoisture always forms frostBSufficient cooling of surface is necessary for condensationCDew has no relation to vapourDDew forms only in clouds

Question 10ExpertLevel 90

Why can dew on a surface and light mist in air form together?

AAir becomes completely dryBNo water vapour remainsCBoth surface and lower air cool with moisture presentDOnly earthquake occurs

Question 11ExpertLevel 90

If frost forms on a surface why will it not be called fog?

ABecause frost has no waterBBecause fog forms inside EarthCBecause frost is always liquid dropletDBecause frost is solid ice crystals on surface and fog is droplets in air

Question 12ExpertLevel 90

If fog is denser on a lower road section which topographic cause is likely?

AAccumulation of cold moist air in the lower partBUpper air becoming zeroCMelting of roadDSoil becoming lava

Question 13ExpertLevel 90

If frost has formed and clouds arrive what may happen to further temperature fall?

ATemperature fall will always become infiniteBClouds can reduce further radiational heat lossCVapour will always disappearDFrost will immediately become rock

Question 14ExpertLevel 90

Why may rainfall not occur even when visibility is low in fog?

AFog has no waterBVisibility has no relation with waterCFog droplets are tiny and suspendedDFog is always dry air

Question 15ExpertLevel 90

In which condition is frost more likely than dew?

ASurface above freezing and near dew pointBSurface hot and dryCSurface temperature below freezing and moisture availableDStrong noon sunshine

Question 16ExpertLevel 90

If a polluted city has high humidity and calm air why does fog risk rise?

APollution removes the SunBHigh humidity prevents fogCCalm air is always dryDParticles provide nuclei and calm moist air lets droplets persist

Question 17ExpertLevel 90

What common scientific element connects mist fog and cloud?

AAll three may contain condensed tiny water droplets or ice particlesBAll three form from rocksCAll three are vapour-freeDAll three deposit only on surfaces

Question 18ExpertLevel 90

If frost remains longer on shaded grass than on sunny grass in morning what is the reason?

AFrost continuously forms in shadeBIce crystals melt later because shaded area receives less heatCSunlight turns frost into stoneDWater vapour is absent in shade

Question 19ExpertLevel 90

If liquid droplets on surface and suspended droplets in air appear together what is the correct matching?

AFrost and snowfallBRain and frostCDew and mistDSalinity and hot wind

Question 20ExpertLevel 90

In which decision is it most necessary to consider both dew point and freezing point?

ADifference between fog and wind directionBDifference between tide and waveCDifference between river and lakeDDifference between dew and frost
