THREE BASIC REASONS:
14
This can lead to afternoon thunderstorms.
15
Which sequence of events affecting moist air within Earth’s atmosphere causes cloud formation? (1) rising → expanding → cooling → condensation (2) rising → contracting → warming → evaporation (3) sinking → expanding → warming → condensation (4) sinking → contracting → cooling → evaporation

19
The result is a “rain shadow” caused by mountain ranges.
22
The cross section below shows the direction of air flowing over a mountain. Points A and B are at the same elevation on opposite sides of the mountain. Compared to the air temperature and humidity at point A, the air temperature and humidity at point B are usually (1) cooler and drier (3) warmer and drier (2) cooler and wetter (4) warmer and wetter
24
more dense less dense
25
The storm symbols probably result from (1) Decreasing atmospheric moisture (2) Increasing humidity (3) Higher atmospheric pressure
