An observer measured the air temperature and the dew-point and found the difference between them to be 12 degrees Celsius. One hour later, the differences between the air temperature and the dew-point was found to be 4 degrees Celsius. Which statement best describes the changes that were occurring?
The relative humidity was decreasing and the chance of precipitation was increasing
The relative humidity was increasing and the chance of precipitation was increasing
The relative humidity was increasing and the chance of precipitation was decreasing

A strong west wind steadily blew over Lake Ontario picking up moisture. As the moist air flowed over the Tug Hill Plateau, the plateau received a 36-inch snowfall. This snow fell from clouds that formed when rising air was
warmed by expansion, causing water vapor to evaporate
cooled by expansion, causing water vapor to condense
cooled by compression, causing water vapor to condense
warmed by compression, causing water vapor to evaporate
When clouds form, heat energy is released into the atmosphere by
expanding air
condensation nuclei
falling precipitation
condensing water vapor
Winds move from regions of
high precipitation towards regions of low precipitation
high humidity toward regions of low humidity
high temperature toward regions of low temperature
high pressure toward regions of low pressure
A container of water is placed in an open outdoor area so that the evaporation rate can be observed. The water will most likely evaporate fastest when the weather is
warm, humid and calm
cool, dry and windy
warm, dry and windy
cool, humid and windy
