Dew

Dew refers to the water droplets that form on surfaces due to the condensation of moist air. This phenomenon usually occurs on cooler objects found near the ground, such as grass and leaves. As the near-surface layer of air cools faster than the layers of air above it, the water vapor present in the air condenses and settles on these objects. Dew can be observed most commonly in the early morning before the sun rises, and it often disappears as soon as the sun begins to warm the ground. The amount of dew that forms depends on various factors, including the humidity of the air, the temperature of the object, and the amount of water vapor in the atmosphere. While dew represents a crucial source of moisture for some plant species, it can also damage crops, fruits, and vegetables by promoting the growth of certain fungi and bacteria. In meteorology, the amount of dew that forms is used as an indicator of atmospheric humidity and the potential for fog.
