Question

question 9 dew point... a is always reached in desert areas. b is the temperature to which the air would have to be warmed for saturation to occur. c is the temperature that needs to be reached in order for clouds, fog, or dew to form. d can never be reached in air that is already very moist.

Explanation:

The dew - point is the temperature at which air must be cooled to become saturated with water vapor. When this temperature is reached, condensation occurs, leading to the formation of clouds, fog, or dew. Desert areas are dry and may not always reach the dew - point. The air needs to be cooled, not warmed, to reach saturation for the dew - point concept. Very moist air can reach its dew - point.

Answer:

C. is the temperature that needs to be reached in order for clouds, fog, or dew to form.
