Description : Why cloudless nights are better for dew deposits than cloudy nights ?

Description : Cloudy nights are wanner compared nights, because clouds mainly – (1) Absorb heat from the atmosphere send it towards earth (2) Prevent cold waves from the sky descending on earth (3) Reflect back the heat given by earth (4) Produce heat and radiate it toward earth
