Fog that forms when the wind blows relatively warm air over a colder surface Fog that most commonly forms on clear nights, with light or calm winds Beads of water that have condensed onto objects near the surface Fog produced when sufficient water vapor is added to the air by evaporation and the moist air mixes with relatively drier air. Fog that forms as moist air flows upward along an elevated surface A tiny liquid drop of dew that freezes when the air temperature drops below freezing Exhaled breath on a cold morning produces this type of fog Fog that forms as warm raindrops evaporate in a cool air mass Ice particles that develop on objects near the surface when the dew point is at or below freezing When fog "burns off " it does this A. Steam fog (evaporation-mixing fog) B. frost C. dew D. upslope fog E. evaporates F. radiation fog G. frozen dew H. evaporation-mixing fog I. advection fog J. precipitation-frontal fog (evaporation-mixing fog)

When cold air passes over warm surface, it condenses and take a form of fog (smoke like appearance). Fog is classified under various categories. Its called radiation fog.

Explanation:

Condensation means transformation of watervapour into liquid. Some forms of condensation are fog, dew, mist etc.

Land surface and water bodies receive insolation at a same time in a same quantity. But during the radiation process land surface cool down much faster than water bodies.

During winter, length of night time is maximum which provides earth surface maximum time to radiate its energy. When it cool down and warm air passes over it, air molecules condenses and creates fog. that is called radiation fog.  

your answer is rising unemployment and inflation.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
