Here in the Midwest of the good ol’ U.S.A. we are accustomed to drastic shifts in temperature within 24 hours. A 40 degree swing in temperature from one day to the next is not uncommon, for example. Sometimes, I can wake up to frost on the ground, and then during the day, the frost layer disappears despite its temperature remaining below freezing. How can this be explained?
A.The frost evaporates due to the sun heating the solid.
B.The frost cycles as does the saturation level of moisture in the winter air does from night to day.
C.The frost melts due to the sun heating the surface of the car above the melting point.
D.The frost sublimes directly from solid ice to water vapor.
E.none of the above
