Practice questions
Why is evaporation considered an initial link of the water cycle?Which sequence correctly explains the process?If actual vapour pressure remains constant and temperature rises what is the main reason for relative humidity decreasing?In a closed room temperature is lowered but the actual amount of water vapour does not change which result is most likely?In which situation will the difference between dew point and air temperature be smallest?At a sea coast strong daytime wind increases evaporation because what does wind do?Which statement shows that absolute humidity and relative humidity are not the same?If air expands and cools while rising after which point is condensation likely to begin?Two places have the same actual water vapour but one place is warmer why may the warmer place have lower relative humidity?At night a clear sky cools the ground rapidly why does this increase the chance of dew formation?In which condition will evaporation of sweat be slowest?Which option best explains the function of condensation nuclei?If relative humidity is (80%) what is its most appropriate meaning?Under which condition is fog formation more likely?If water takes heat from surroundings during evaporation what effect can it have on the surroundings?In which condition may rainfall not reach the ground even after cloud formation?Why is understanding the combined effect of transpiration and evaporation important in water budget?In a valley cold air collects at night and humidity is high near the surface which event is likely?If actual vapour pressure and saturation vapour pressure are equal what will relative humidity be?Why do cloud droplets not fall immediately as rain after they form?
