Clouds and precipitation

Question 1ExpertLevel 91

If a cloud has very strong vertical development why can sudden heavy rainfall occur?

ABecause droplets can grow quickly and fallBBecause cloud has no waterCBecause vertical development stops rainDBecause cloud becomes stone

Question 2ExpertLevel 91

What does the presence of both water droplets and ice crystals in a cloud indicate?

AAll particles are rocksBThe cloud has varying temperature and height conditionsCThe cloud has no moistureDPrecipitation is impossible

Question 3ExpertLevel 91

If a cloud is thin and droplet growth is limited what result is more likely?

AVisible cloud but weak or nearly absent precipitationBHeavy hailstorm is compulsoryCEarthquakeDOnly surface frost

Question 4ExpertLevel 91

What is the most correct contribution of tiny dust particles in a cloud?

AThey can provide surfaces for condensationBThey always remove water vapourCThey turn cloud into lavaDThey are unrelated to precipitation

Question 5ExpertLevel 91

If a cumulus cloud is continuously growing vertically what risk may increase?

AStorm rainfall or cumulonimbus developmentBCompletely clear weatherCDrying of riverDOnly surface frost

Question 6ExpertLevel 91

Why is the freezing level important in understanding forms of precipitation?

ABecause it indicates whether falling water remains solid or meltsBBecause it changes river directionCBecause it tells rock ageDBecause it has no relation with water

Question 7ExpertLevel 91

If falling snowflakes partially melt what may reach the ground?

AMixed rain and snowBHailstonesCOnly dustDCompletely dry air

Question 8ExpertLevel 91

If maritime moist air continuously reaches a mountain area why can rainfall be greater on the windward slope?

AMoist air is forced upward and coolsBMoist air descends and warmsCMaritime air has no vapourDMountains always dry air first

Question 9ExpertLevel 91

If raindrops are very large why can their surface impact increase with strong wind?

ABecause large drops can have greater kinetic impactBBecause large drops have no waterCBecause wind removes gravityDBecause rain becomes rock

Question 10ExpertLevel 91

Why are both height and form useful in cloud classification?

ABecause they indicate thermal state and cloud structureBBecause they show rock colourCBecause all clouds are sameDBecause clouds have no relation to weather

Question 11ExpertLevel 91

If coalescence of droplets in a cloud is rapid why does rainfall chance increase?

ADroplets can quickly reach fallable sizeBDroplets always disappearCDroplets become rocksDCoalescence makes rain impossible

Question 12ExpertLevel 91

Less light reaching below a dark cloud can indicate what?

AGreater cloud thickness or densityBAbsence of water in cloudCCloud being rockDCloud always being cirrus

Question 13ExpertLevel 91

In which condition is drizzle from cloud to ground more likely?

ASmall fine liquid droplets fall slowlyBLarge icy balls fallCSnowflakes fall without meltingDFrost deposits on surface

Question 14ExpertLevel 91

If lower air is cold and upper air has ice crystals why does snowfall reaching the ground become more likely?

ABecause ice crystals can avoid meltingBBecause cold air destroys vapourCBecause ice crystals become rocksDBecause cold air always stops precipitation

Question 15ExpertLevel 91

If air becomes warm and dry after crossing a mountain which effect is clear?

ARain shadow effectBConvectional thunderCSea tideDSnowfall increase

Question 16ExpertLevel 91

In which condition is widespread slow rain more likely than sudden hailstorm?

ALayered nimbostratus clouds are presentBStrong cumulonimbus updrafts are presentCLarge hail is circulating in cloudDAir is very unstable

Question 17ExpertLevel 91

If a cloud has enough moisture but very few condensation nuclei what problem may occur in droplet formation?

AVapour will have fewer surfaces to form dropletsBRain will immediately be heavyCCloud will become rockDMoisture will become soil completely

Question 18ExpertLevel 91

Which is the most balanced scientific explanation of clouds and precipitation?

AClouds are condensed particles and precipitation occurs when particles become fallableBEvery cloud gives heavy rainCPrecipitation has no relation with vapourDClouds are rocks

Question 19ExpertLevel 91

If droplets repeatedly move upward in a storm cloud which precipitation hazard can increase?

AHailstormBSurface dewCFogDClear sky

Question 20ExpertLevel 91

If some falling drops evaporate and some reach the ground what effect occurs on rainfall measurement?

AMeasured surface rain may be less than water released from cloudBMeasured rain will always be moreCDrops will become rocksDRain measurement will necessarily be zero
