900.8 mb
1000.8 mb

Why is it possible for no rain to be falling from a cloud?
The water droplets are too small to fall.
The cloud is water vapor.
The dewpoint has not yet been reached in the cloud.
There are no condensation nuclei in the cloud.
Most clouds form in the atmosphere when moist air
rises, expands, and cools to the dewpoint
rises, expands, and warms to the dewpoint
sinks, compresses, and cools to the dewpoint
sinks, compresses, and warms to the dewpoint
Under which atmospheric conditions will water most likely evaporate at the fastest rate?
hot, humid, and calm
hot, dry, and windy
cold, humid, and windy
cold, dry, and calm
As the temperature of a given volume of saturated air decreases, condensation
Increases
Remains the same
Decreases
On an afternoon in NYS, the barometric pressure drops to 28.5 inches falling. This most likely indicates
A Storm is approaching
Skies are rapidly clearing
Continuous fair weather
Conditions gradually improving
