Which condition(s) is(are) necessary for the formation of dew?
AI Explanation
The correct answer is D) All of the above.
For dew to form, the following conditions must be met:
1) The Earth's surface must be cooler than the dew point of the air, causing water vapor in the air to condense on the surface.
2) Clear skies allow the Earth's surface to radiate heat and cool more effectively.
3) Calm air prevents mixing of the air and disruption of the cooling process.
All three of these conditions - surface temperature below dew point, clear skies, and calm air - are necessary for dew formation to occur. The other answer choices do not fully describe the complete set of required conditions.
