Collect data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions.
Emphasis is on how air masses flow from regions of high pressure to low pressure, causing weather (defined by temperature, pressure, humidity, precipitation, and wind) at a fixed location to change over time, and how sudden changes in weather can result when different air masses collide. Emphasis is on how weather can be predicted within probabilistic ranges. Examples of data can be provided to students (such as weather maps, diagrams, and visualizations) or obtained through laboratory experiments (such as condensation).

Q 1/13
Score 0
What happens when a cold, dry air mass meets a warm, moist air mass?
30
The warm air rises, forming clouds and possible precipitation.
The warm air sinks, causing high pressure.
The cold air rises and clears the skies.
The two masses cancel each other out.
Q 2/13
Score 0
Which statement best explains how different air masses cause weather changes?
30
The interaction of different temperatures and humidity causes changes in weather.
The shape of clouds controls the weather.
All air masses bring the same weather.
Air masses change weather through conduction.
