7.3 CW 3

3. Transition zone where two air masses meet, producing changes in temperature, wind, and precipitation
6. Large body of rising air that often produces clouds, wind, and precipitation
8. Apparent curving of winds and ocean currents due to Earth’s rotation
9. Large body of air with distinct temperature and moisture characteristics
12. A circulation pattern created by fluids (gases or liquids) in which less dense fluids rise and denser fluids sink
13. Steady winds that blow toward the equator, influencing tropical weather and ocean currents
15. Amount of water vapor in the air
17. The variations of weather conditions over long periods of time
18. winds that blow mostly in one direction, moving air masses
19. Boundary between two air masses where weather changes often occur

1. Boundary where a warm air mass slides over a cold air mass, producing gentle rain or steady clouds
2. Process of gases in the atmosphere like carbon dioxide, methane, and water vapor that absorb infrared light and redirect it back toward Earth, which keeps Earth warm
4. Boundary where a cold front overtakes a warm front, lifting warm air and causing complex precipitation
5. Boundary between air masses that moves little, often bringing clouds and steady precipitation
7. Continuous movement of ocean water driven by wind, temperature, and salinity differences
10. Increase in Earth’s average surface temperature over the past century
11. Large body of sinking air that brings clear skies and calm, dry weather
14. Violent winter storm with freezing temperatures, strong winds, and blowing snow
16. Fast-moving band of air in the upper atmosphere that influences weather and storm paths
17. Boundary where a cold air mass pushes under a warm air mass, often causing storms or heavy rain
