Across 2. short term variations in atmosphere phenomenon that interact and affect the environment and life on Earth 4. to soak up 10. the change that Earth’s rotation causes in the motion of objects and that explains how the winds curve; the combination of the Coriolis Effect and the Earth’s heat imbalance, creates the trade winds, polar easterlies, and prevailing winds 13. two global wind systems that flow between 300 north and south latitudes, where air sinks, and warm and returns to the equator in westerly direction 15. global wind systems that line between latitudes 600N and 600S and the poles and is characterized by cold air 18. outermost layer of the Earth’s atmosphere that is located above the thermosphere with no clear boundary at the top; transitional region between Earth’s atmosphere and outer space 19. the transfer of thermal energy between objects in contact by the collisions between the particles of the objects 20. layer of the atmosphere closest to Earth’s surface mass of where most of the atmosphere is found and in which most weather takes place and air pollution collects

Down 1. region area over which an air mass forms 3. the transfer of thermal energy by electromagnetic waves; the transfer of thermal energy from the sun to the Earth by radiation 5. layer of Earth’s atmosphere above the stratopause 6. global wind system that lies between 300 and 600 north and south latitudes where surface air moves toward the poles in an easterly direction 7. boundary between two air masses of differing densities; can be cold, warm, stationary, or occluded and can stretch over large areas of Earth’s surface 8. narrow wind band that occurs above large temperatures contrasts and can flow as fast as 185km/hr. 9. cutoff, as in a front where warm air is caught between two cooler air masses 11. layer of Earth’s atmosphere that is located above the tropopause and is made up primarily of ozone 12. layer of Earth’s atmosphere that is located above the mesopause; oxygen atoms absorb solar radiation causing the temperature to increase in this layer 14. the transfer of thermal energy by the movement of heated material from one place to another 16. large volume of air that has the characteristics of the area over which it forms 17. the long-term average of variations in weather for a particular area
