Humidity, evaporation, and condensation

Question 1MediumLevel 87

Why is evaporation considered an initial link of the water cycle?

AIt carries water to the atmosphere as moistureBIt turns rainfall into rockCIt removes all gases from airDIt permanently freezes oceans

Question 2MediumLevel 87

Which sequence correctly explains the process?

AEvaporation then water vapour then cooling then condensationBCondensation then evaporation then drought then frostCPrecipitation then rock then vapour then pressureDMoisture then earthquake then cloud then salinity

Question 3HardLevel 85

If actual vapour pressure remains constant and temperature rises what is the main reason for relative humidity decreasing?

AActual vapour pressure decreasesBWater vapour immediately becomes rainfallCSaturation vapour pressure increasesDAir pressure always becomes zero

Question 4HardLevel 85

In a closed room temperature is lowered but the actual amount of water vapour does not change which result is most likely?

ARelative humidity will increaseBRelative humidity will always be zeroCAbsolute humidity will automatically doubleDCondensation will be impossible

Question 5HardLevel 85

In which situation will the difference between dew point and air temperature be smallest?

AVery dry airBNearly saturated airCStrong hot desert airDCompletely dust free air

Question 6HardLevel 85

At a sea coast strong daytime wind increases evaporation because what does wind do?

AMakes water solidBStops solar radiationCRemoves sea salinityDRemoves the moist layer near the surface

Question 7HardLevel 85

Which statement shows that absolute humidity and relative humidity are not the same?

AOne is actual vapour amount and the other is percentage of capacityBBoth always give the same numberCBoth measure only rainfall heightDBoth tell only cloud colour

Question 8HardLevel 85

If air expands and cools while rising after which point is condensation likely to begin?

ASea levelBMaximum pressure pointCDew point temperatureDMaximum wind speed

Question 9HardLevel 85

Two places have the same actual water vapour but one place is warmer why may the warmer place have lower relative humidity?

ANo water vapour remains thereBAir saturation capacity is higher thereCClouds always form thereDRain gauge is wrong there

Question 10HardLevel 85

At night a clear sky cools the ground rapidly why does this increase the chance of dew formation?

AAir pressure increases and creates vapourBSolar heat increasesCRain starts immediatelyDGround temperature may reach near dew point

Question 11HardLevel 85

In which condition will evaporation of sweat be slowest?

AHigh relative humidity and calm airBLow relative humidity and strong windCHigh temperature and dry airDLow temperature and strong dry wind

Question 12HardLevel 85

Which option best explains the function of condensation nuclei?

AThey always keep temperature constantBThey directly change rain into iceCThey provide tiny surfaces for vapour to form dropletsDThey remove salinity from oceans

Question 13HardLevel 85

If relative humidity is (80%) what is its most appropriate meaning?

AAir has (80%) oxygenBAir holds (80%) of its saturation capacity of water vapourCRain chance is certainly (80%)DTemperature is (80^\circ)

Question 14HardLevel 85

Under which condition is fog formation more likely?

AHot dry afternoonBBright sunshine and low moistureCHigh temperature and very little vapourDMoist air near the surface cooling to dew point

Question 15HardLevel 85

If water takes heat from surroundings during evaporation what effect can it have on the surroundings?

ASurroundings may feel coolerBEarthquake always occurs in surroundingsCSurrounding pressure becomes zeroDWater vapour ends in surroundings

Question 16HardLevel 85

In which condition may rainfall not reach the ground even after cloud formation?

AWhen droplets become large in cloudBWhen lower air is very dry and droplets evaporateCWhen relative humidity is (100%)DWhen condensation nuclei are present

Question 17HardLevel 85

Why is understanding the combined effect of transpiration and evaporation important in water budget?

AIt shows seismic energyBIt completely removes sea salinityCIt estimates total moisture going from surface to atmosphereDIt only changes cloud colour

Question 18HardLevel 85

In a valley cold air collects at night and humidity is high near the surface which event is likely?

ASand stormBSea tideCBoiling of waterDValley fog

Question 19HardLevel 85

If actual vapour pressure and saturation vapour pressure are equal what will relative humidity be?

A(100%)B(50%)C(0%)D(10%)

Question 20HardLevel 85

Why do cloud droplets not fall immediately as rain after they form?

AThey immediately become gasBThey are very small and can remain suspended in air currentsCThey turn into rockDThey change air to zero pressure
