Where does water collect when dew forms?

Correct answer: On grass, leaves, and cool surfaces

Correct answer: D, on grass, leaves, and other cool surfaces. At night, surfaces near the ground can lose heat and become cooler than the surrounding air. Air touching these surfaces may cool to its dew point. At that point, water vapour changes into tiny liquid droplets, and the droplets collect directly on the surface. This is why dew is seen on grass, leaves, plant stems, vehicles, and similar objects in suitable conditions. A is wrong because water vapour or clouds in the upper atmosphere are not dew. B is wrong because dew does not collect below sea level as a defining process. C is wrong because dew is a surface deposit, not water accumulating inside the Earth. D is correct because it identifies the location where the condensation is visible. Do not confuse dew with rain: rain falls from clouds, whereas dew forms quietly on cooled surfaces. Memory cue: dew means droplets deposited on the surface.
