WHY is it more likely to be frost on a clear night than in à cloudy night?

Frost forms when the temperature of surfaces drops below the dew point, causing moisture in the air to condense and freeze. On clear nights, heat from the ground escapes into the atmosphere more readily, leading to cooler surface temperatures. In contrast, clouds act as an insulating layer, trapping heat and preventing significant temperature drops. Therefore, clear nights are more conducive to frost formation compared to cloudy nights.
