Clouds and precipitation

Question 1HardLevel 92

Which is the correct sequence for higher rainfall on the windward side in orographic rainfall?

AMoist air rises cools condenses and gives rainBAir descends warms and gives rainCAir dries then clouds formDAir becomes rock then water falls

Question 2HardLevel 92

Why does warm air rise over cold air in cyclonic rainfall?

ABecause warm air is less denseBBecause warm air becomes stoneCBecause cold air always disappearsDBecause water vapour has no effect

Question 3HardLevel 92

If moist air from the sea strikes a coastal mountain on which side is heavy rain more likely?

AOn the windward sea-facing slopeBOn the leeward dry slopeCInside the ground below the mountainDAlways equally on both sides

Question 4HardLevel 92

What is the main physical difference between cloud droplets and raindrops?

ACloud droplets are small and suspended while raindrops are larger and fallBCloud droplets are rocksCRaindrops contain no waterDThere is no size difference

Question 5HardLevel 92

If ice crystals formed aloft completely melt while descending what precipitation will reach the ground?

ARainBFrostCMistDHail

Question 6HardLevel 92

Which change is most important for cumulus to become cumulonimbus?

AStrong vertical growth and unstable moist airBCloud becoming rockCAir becoming completely dryDFrost depositing on surface

Question 7HardLevel 92

Why is drizzle lighter than normal rain?

ABecause very small droplets fall in itBBecause icy stones fall in itCBecause it has no waterDBecause it is only an earthquake

Question 8HardLevel 92

If the upper layer of a cloud has ice crystals and the lower layer has liquid droplets what is the cause?

ADecrease of temperature with heightBAbsence of water vapourCCloud being rockDOcean salinity

Question 9HardLevel 92

Why do dark rain clouds appear darker from below?

ABecause they are dense and transmit less sunlightBBecause they are made of black stonesCBecause they have no water particlesDBecause they always form at night

Question 10HardLevel 92

In which condition is rainfall intensity more likely to be high?

AWhen drops are numerous and largeBWhen drops are only invisible gasCWhen cloud has no waterDWhen air is completely dry

Question 11HardLevel 92

If condensation occurs in a cloud but droplets do not grow what result is most likely?

ACloud will remain but precipitation will be weak or absentBHeavy hail will be compulsoryCAll droplets will become rocksDEarthquake will occur at the surface

Question 12HardLevel 92

What can be the weather indicator importance of cirrus clouds?

AThey may sometimes indicate approaching weather changeBThey always indicate earthquakesCThey indicate drying of the seaDThey always give immediate heavy rainfall

Question 13HardLevel 92

If a cloud is low layered widespread and giving long lasting light rain which cloud is more likely?

ANimbostratusBCirrusCCumulusDCumulonimbus

Question 14HardLevel 92

Why do fewer clouds form in a rain shadow region due to descending air?

ADescending air warms and becomes more unsaturatedBDescending air is always coldCAir ceases to existDMountain increases vapour there

Question 15HardLevel 92

Cloud and fog may have similar structure yet why are they named differently?

AThe main difference is their location or heightBFog has no waterCCloud is always rockDNeither has tiny droplets

Question 16HardLevel 92

If moisture is sufficient but air does not rise and cool what is the obstacle to cloud formation?

ANecessary cooling for condensation will not occurBMoisture will always form cloudsCAir will immediately form hailDVapour will become rock

Question 17HardLevel 92

In which process do small droplets collide and join to form larger drops?

ACollision and coalescenceBEarthquake and volcanoCSalinity and tideDWeathering and erosion

Question 18HardLevel 92

If a storm cloud has strong upward motion and rainfall downward what cloud does it indicate?

ACumulonimbusBCirrusCLight stratusDFog

Question 19HardLevel 92

If a mountain is high but the air is dry why will orographic rainfall be limited?

ABecause there will not be enough water vapour for condensationBBecause mountains stop all rainCBecause dry air always gives heavy rainDBecause height has no relation with cooling

Question 20HardLevel 92

Rain and drizzle are both liquid precipitation yet why are they differentiated?

AOn the basis of drop size and falling intensityBBecause drizzle has no waterCBecause rain is always solidDBecause both are rock processes
