Weather Exam Study Guide
AIR PRESSURE
1. Air is made out of:
2. Density = mass/ volume
When something is more dense, what is
going on with the molecules? Draw
When something is less dense,
what is going on with the molecules? Draw
3. Circle the correct answers that correspond to warm air or cold air:
Warm Air
Less dense
High air pressure
Molecules close
Floats to top
More mass
More dense
Low air pressure
molecules far
sinks to bottom
less mass
Cold Air
Less dense
High air pressure
molecules close
floats to top
more mass
More dense
Low air pressure
molecules far
sinks to bottom
less mass
