The cooling of the ground to produce dew is mainly the result of
A) conduction.
B) radiational cooling.
C) cooling due to the release of latent heat.
D) advection.

Question

Quizplus · Accepted Answer

Radiational cooling occurs when the ground loses heat through radiation. As the night sky is usually clear and devoid of clouds, the ground loses heat to space, causing the surface to become cooler than the surrounding air. This process leads to the formation of dew as the moisture in the air condenses on the cooler surface. Conduction (A) is the transfer of heat between two objects in contact, which is not the primary mechanism for the ground to cool for dew formation. Cooling due to the release of latent heat (C) occurs when water vapor in the air condenses, but this is a separate process from ground cooling to cause dew formation. Advection (D) is the horizontal movement of air, which does not contribute to ground cooling for dew formation.
