5.  What is wind?

9.  What influences wind direction?
 What influences wind speed?

15.  Let’s figure out step-by-step, what happens to a
rising air parcel.

16. 33%
33%
33% 1. Will rise
2. Will sink
3. Will maintain its vertical position

17. 50%
50% 1. Be subject to lessening air pressure
2. Be subject to increased air pressure

18. 33%
33%
33% 1. Expand in volume
2. Contract in volume
3. Stay the same size

19. 50%
50% 1. Collide with each other more
2. Collide with each other less

20. 50%
50% 1. Speed up
2. Slow down

21. 50%
50% 1. Less kinetic energy, lower temperature
