Weather – Study Questions
When water droplets in a cloud
combine, become too heavy, and fall
to the ground as rain, snow, sleet, or
hail, we are experiencing ____.
Masses of puffy, white clouds,
often with flat bases, that form
when air currents rise are
called ____ clouds.
____ forms when raindrops
pass through a layer of
freezing air near Earth's
surface, forming ice pellets.
____ forms when the air
temperature is below freezing
and water vapor changes directly
to solid.
To keep track of high-and lowpressure areas, weather maps are
drawn with lines connecting points
of equal atmospheric pressure.
These lines are called ____.
Weather expected?
Clouds form as warm air rises,
expands, cools, and becomes
saturated, and then ____
condense(s) into tiny drops,
which collect.
____ humidity is a measure of the
amount of water vapor that air is
holding compared to the amount
needed for saturation at a specific
temperature.
