Practice questions
Why may less dew form on a cloudy night compared with a clear night?How can strong wind reduce dew formation?How can saturation for fog formation be achieved?Why does fog formation become more likely when dew point and air temperature are very close?When will a white layer on a cold road at night be called frost instead of dew?When very tiny water droplets remain suspended near the ground and reduce visibility, which process is central?Which fog can form from moist air rising along a mountain slope?Which two factors combine to form advection fog on a coast?What can be the most common reason when fog dissipates?Why can different amounts of dew appear on surfaces like grass and metal?How does the lower vapour-holding capacity of cold air help fog formation?If air is dry but the surface is very cold, what may prevent dew formation?Why is fog called a cloud formed near the ground?Which statement gives the correct sequence of dew formation?What is the scientific reason for a local condition called a frost hollow?Why are both dew and frost considered surface forms?Why is it said that fog is not guaranteed by high humidity alone?What is the main difference between radiation fog and advection fog?If the Sun is visible through light haze-like moisture and objects are only slightly unclear, what does it indicate?What is the effect of very small fog droplets on visibility?
