Clouds and precipitation

Question 1ExpertLevel 93

Why is it scientifically incomplete to treat cloud and precipitation as the same process?

AA cloud is a group of condensed particles and precipitation occurs when they become fallableBEvery cloud gives heavy rainCPrecipitation forms from rockDClouds have no water

Question 2ExpertLevel 93

If the atmospheric column has moisture but a dry layer in the middle what effect can occur on surface rainfall?

AThe dry layer can reduce or evaporate falling particlesBSurface rainfall will always doubleCDry layer turns hail into lavaDThere will be no effect

Question 3ExpertLevel 93

If widespread layered clouds gradually change into vertically developed clouds how can rainfall style change?

AFrom steady light rain toward local intense rainBFrom rain toward earthquakeCFrom cloud toward rockDFrom snow toward lava

Question 4ExpertLevel 93

If large particles form in a cloud but strong uplift continues why may they not fall immediately?

ARising air can oppose their fallBThey become vapour freeCGravity disappearsDParticles become rocks

Question 5ExpertLevel 93

If clouds appear in a rain shadow area but rainfall remains low what conclusion is appropriate?

ACloud presence always gives heavy rainBDroplet growth or lower dryness can limit rainCThere is no air thereDClouds are made of rock

Question 6ExpertLevel 93

If turbulence is high in a cloud what balanced effect on droplet size is possible?

ACollision growth and breakup both can occurBAll droplets become soilCDroplets become waterlessDPrecipitation always stops

Question 7ExpertLevel 93

If moisture is high and uplift is continuous why is precipitation chance from cloud strong?

AContinuous cooling supports condensation and droplet growthBUplift always removes moistureCMoisture stops precipitationDCloud becomes rock

Question 8ExpertLevel 93

If only high thin cirrus clouds are present why is heavy surface rainfall unlikely?

AThey are made of rockBThey are generally thin ice-crystal clouds with limited precipitation particle growthCThey are at the groundDThey always give hailstorm

Question 9ExpertLevel 93

If droplets fall from a cloud but both melting and evaporation are possible in lower air what will final precipitation depend on?

ATemperature and humidity conditions of the whole air columnBColour of rocksCSea tideDName of the ground

Question 10ExpertLevel 93

If moist air keeps rising on a windward slope for a long time why can rainfall persist?

AContinuous uplift maintains cooling and condensationBMountain ends the airCRising air is always dryDRain has no relation with moisture

Question 11ExpertLevel 93

If below-freezing zones are small in a storm cloud what will hinder large hail growth?

ATime and zone for ice-layer growth will be limitedBThere will be no air in cloudCNo droplets will ever form rainDUpdraft will remove gravity

Question 12ExpertLevel 93

If raindrops are large and wind is also strong why can surface impact increase?

ALarge drops and wind can bring greater kinetic impactBLarge drops contain no waterCWind removes gravityDRain becomes rock

Question 13ExpertLevel 93

Why can it be wrong to use only colour in cloud classification?

AColour alone does not fully show height form and particle natureBColour always tells cloud nameCCloud shape is unimportantDHeight has no relation to clouds

Question 14ExpertLevel 93

If small liquid drops are continuously falling from a cloud but they are not large raindrops which form is likely?

AHailstormBSnowfallCDrizzleDFrost

Question 15ExpertLevel 93

If droplet growth is rapid and lower air is not very dry why does surface rainfall chance increase?

ADrops can become fallable and reach surface with less evaporationBDrops become rocksCLower air always stops precipitationDRapid growth destroys water

Question 16ExpertLevel 93

If a cloud has enough moisture uplift and condensation nuclei yet rain is low what cause is possible?

ADroplets did not grow to fallable sizeBCloud had no waterCUplift always prevents rainDCondensation nuclei are rocks

Question 17ExpertLevel 93

If low clouds form above a river valley while higher clouds occur nearby which local factor can help explain it?

AValley moisture and local cool airBMelting of rockCDrying of seaDComplete absence of air

Question 18ExpertLevel 93

If heavy rain occurs at the surface in a short time what immediate water cycle effect can occur?

ARapid surface runoff can increaseBEvaporation will completely stopCWater vapour will become rockDClouds will become permanent

Question 19ExpertLevel 93

If supercooled liquid droplets exist in a cloud why are they considered different from ordinary liquid droplets?

AThey can remain liquid below freezing pointBThey are waterlessCThey are only rockDThey always stay on ground

Question 20ExpertLevel 93

If a weather system first gives widespread layered rain and later local thunder rain what change is indicated?

AUplift nature changed from layered to convectiveBWater vapour disappearedCClouds became rocksDPrecipitation lost relation with cloud
