Practice questions
Why is abundance of water vapour in the troposphere important for meteorology?If the ground cools rapidly but the air is very dry why will less dew form?Which calculation correctly uses relative humidity?Direct change of water vapour into ice crystals is an example of which process?What is the main reason clouds form more on the windward slope in mountains?If temperature at height is below freezing in what form can condensed moisture remain in cloud?Why does body temperature regulation become difficult in sultry weather?Under which condition is evaporation from a water surface most likely to be low?If the dew point of a place is far below the current temperature what does it indicate?Why may dew be seen on grass in the morning but less on a nearby warmer road?Which option gives the correct energy relation and state change for evaporation and condensation?Under which condition can air reach saturation quickly?If actual water vapour content remains the same but temperature rises, why does relative humidity generally decrease?Why is dew point temperature considered a more reliable indicator of moisture content?What is the most suitable combined reason for rapid evaporation on a hot and dry day?If air is saturated and water is available at the surface, why will evaporation still be very low?Why is water vapour alone not enough for condensation to begin?What is the main process behind cloud formation in air rising along a mountain slope?Despite high evaporation over oceans, why does relative humidity not always remain the same?Why is dew more likely to form on clear nights?
