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

Question 1MediumLevel 89

Which measure is most useful while differentiating dense fog and light mist?

ASea wave heightBRock hardnessCVisibility distanceDSoil colour

Question 2MediumLevel 89

Which statement correctly matches dew and frost?

ADew is solid and frost is liquidBBoth only float in airCDew does not form on leavesDDew is liquid droplet and frost is ice crystal

Question 3MediumLevel 89

Why can the environment near a water body be favourable for mist formation?

AIt gives moisture to the airBIt completely burns airCIt always keeps temperature very highDIt removes water vapour

Question 4MediumLevel 89

If small droplets are on the outer surface of a car in the morning what may be their source?

AFuel inside the carBMoist air of the atmosphereCRoad rockDMelting of car metal

Question 5MediumLevel 89

Why is air near saturation needed for fog formation?

ABecause only then water vapour can turn into tiny dropletsBBecause saturation turns air into stoneCBecause saturation removes all moistureDBecause saturation stops the Sun

Question 6MediumLevel 89

Which one among frost and dew can be more harmful to crops?

ADew because it is liquidBBoth always give equal benefitCMist because it deposits on surfaceDFrost because ice crystals can damage tissues

Question 7MediumLevel 20

In which form do droplets remain deposited on a surface and not suspended in air?

ADewBFogCMistDSmoke

Question 8MediumLevel 89

Why are dew frost fog and mist placed in the same group?

ABecause all are sea wavesBBecause these are forms linked with condensation of atmospheric water vapourCBecause all are rocksDBecause these are types of earthquakes

Question 9MediumLevel 89

If light mist is seen over an open water body on a cold morning what is the most appropriate reason?

AMoisture from the water body and cooling of lower airBWater of the reservoir turning into stoneCComplete absence of water vapour in airDSudden disappearance of solar heat

Question 10MediumLevel 89

How is the role of temperature best understood in identifying frost and dew?

ATemperature has no relation with eitherBAbove freezing liquid dew and below freezing icy frost can formCFrost forms only at very high temperatureDDew always forms as ice crystals

Question 11MediumLevel 89

Why are objects ahead not clearly visible in dense fog?

ATiny droplets in air scatter lightBGravity disappears in airCGround changes into seaDFog is only dry dust

Question 12MediumLevel 90

If air is moist but wind is very strong why may less dew form?

AStrong wind prevents a stable cool moist layer near the surfaceBStrong wind always turns vapour into iceCStrong wind makes the Sun hotterDStrong wind changes the surface into soil

Question 13MediumLevel 89

What is the correct reason for calling mist a lighter form than fog?

AMist has no water dropletsBMist always forms from ice crystalsCVisibility in mist is not as low as in fogDMist forms only inside the Earth

Question 14MediumLevel 90

What is the main similarity between fog and cloud?

ABoth may consist of tiny water droplets or ice crystalsBBoth are made only of dustCWater vapour has no role in eitherDBoth form only in deserts

Question 15MediumLevel 90

What is the main basis for distinguishing mist from fog?

AAmount of rainfallBRange of visibilityCSoil fertilityDDistance of the Sun

Question 16MediumLevel 90

What is the most important difference between dew and frost?

ADew forms as liquid droplets and frost as ice crystalsBDew forms only on mountains and frost only over seasCDew has no condensation and frost has evaporationDThere is no temperature difference between them

Question 17MediumLevel 90

Why do clear nights help dew formation?

AThe surface cools rapidly by longwave radiationBThe Sun gives more heat at nightCWater vapour is destroyed in airDThe surface always remains warm above freezing

Question 18MediumLevel 90

How does strong wind affect the chance of dew formation?

AIt can reduce dew by removing saturated air near the surfaceBIt always greatly increases dewCIt turns water vapour into stoneDIt has no effect

Question 19MediumLevel 90

Which air condition near the surface is more necessary for fog formation?

ASaturated or nearly saturated airBCompletely dry airCVery hot and dust-free airDAir containing only oxygen

Question 20MediumLevel 90

Why can fog be common in valleys during morning?

ACold dense air collects in valleysBThe Sun never rises in valleysCThere is no water vapour thereDValleys are always below sea level
