Modification• Air masses take on the characteristics of the
surface over which they form but are modified, in whole or in part, as they move over different surfaces.
• If the modification is extensive the air mass may be given a new name.

Congratulations!
You have now completed the Air Masses lesson of the Meteorology Module. Of course, this lesson is always available to you for future reference if required.
You are now ready to move along to the next Meteorology lesson you have not completed or to any other module you wish. You can advance to the Self Test Module if you feel ready to challenge the final exam.
Good Luck!
