Clouds and precipitation

Question 1MediumLevel 93

Why is the presence of cloud alone not enough for rainfall?

ADroplets must also grow to a fallable sizeBEvery cloud never has waterCClouds are made of rocksDRainfall is unrelated to clouds

Question 2MediumLevel 93

If falling raindrops evaporate in dry lower air what will happen at the ground?

ARain will reach little or not reach the groundBHail will necessarily formCFrost will form on groundDCloud will become rock

Question 3MediumLevel 93

What clearly shows the main difference between drizzle and normal rain?

ABy the size of dropsBBy colour of rocksCBy name of windDBy distance of the Sun

Question 4MediumLevel 93

What may happen if snowfall passes through a warm lower layer below the cloud?

AIt may melt and become rainBIt will become lavaCIt will become rockDIt will always return upward

Question 5MediumLevel 93

Why are strong updrafts important in hail formation?

AThey repeatedly carry ice particles upward in the cloudBThey remove all moistureCThey turn cloud into groundDThey cool the Sun

Question 6MediumLevel 93

Why can both water droplets and ice crystals be present together in a cloud?

ADifferent parts of cloud can have different temperaturesBCloud is always rockCAir has no water vapourDAll clouds are on ground

Question 7MediumLevel 93

Why do dense clouds appear dark from below?

AThey block more sunlightBThey are made of black stoneCThey contain no waterDThey always form at night

Question 8MediumLevel 93

What is the contribution of condensation nuclei in cloud formation?

AThey give vapour a surface to form dropletsBThey always stop rainfallCThey make air rockyDThey burn all droplets

Question 9MediumLevel 93

What is the correct shape-based difference between stratus and cumulus clouds?

AStratus are layered and cumulus are heap-likeBStratus are hail and cumulus are rainCBoth are always invisibleDCumulus is only frost

Question 10MediumLevel 93

What change occurs in the water cycle when precipitation falls from clouds?

AAtmospheric water returns to the groundBRock moves to the SunCSea becomes earthquakeDAir completely ends

Question 11MediumLevel 93

If air has moisture but no cooling what problem will occur in cloud formation?

AVapour will not condense into dropletsBHail will form immediatelyCClouds will become stonesDRainfall will be compulsory

Question 12MediumLevel 93

In which situation will orographic rainfall be higher?

AMoist air rising on windward slopeBDry air descending on leeward slopeCCompletely dry air in plainDFrost on surface

Question 13MediumLevel 93

If droplets in a cloud are very small how can they remain in the air?

AThey can remain suspended because they are lightBThey become rockCGravity does not act on themDThey are unrelated to Earth

Question 14MediumLevel 93

Cumulus clouds are most related to which air movement?

ARising of warm airBDescending of cold rockCDrying of seaDAbsence of air

Question 15MediumLevel 93

If a cloud is very thin and high why may rainfall reach the ground less?

AGrowth of rain-sized drops may be limitedBIt is made of rockCIt is only inside EarthDIt has no light

Question 16MediumLevel 93

Which is the correct example of solid forms of precipitation?

ASnowfall and hailBDew and fogCRain and drizzleDMist and frost

Question 17MediumLevel 93

Cyclonic rainfall is linked with which basic process?

AMeeting and uplift of different air massesBMelting of rocksCDrying of seaDComplete absence of air

Question 18MediumLevel 93

Clouds are generally classified on which two bases?

AHeight and formBRock and soilCRiver and seaDVolcano and earthquake

Question 19MediumLevel 93

If clouds are spread like a uniform layer in the sky which cloud type is likely?

AStratusBCumulusCCirrusDCumulonimbus

Question 20MediumLevel 93

How can droplet size in a cloud affect rainfall intensity?

ALarger and more numerous drops can give heavier rainBSmall droplets always give heavy rainCDroplet size is unimportantDDroplets become rocks
