Across
- 3. Circular movements of air or liquid caused by heat differences.
- 7. The distance north or south of the Equator, measured in degrees.
- 8. A boundary where cold air moves in and pushes warm air up, often causing storms.
- 9. A large, rotating storm system with strong winds and heavy rain that forms over warm ocean water.
- 12. A warm air mass that forms near the Equator.
- 17. A boundary where warm air moves in over cold air, bringing light rain.
- 18. A scale used to measure tornado intensity based on wind speed and damage.
- 20. A rapidly rotating column of air that touches the ground, causing destruction.
- 25. The pressure exerted by the atmosphere, measured in millibars.
- 26. The transfer of heat through direct contact between substances.
- 27. The different gases and substances that make up Earth's atmosphere.
- 30. A cold air mass that forms near the poles.
- 31. A wind that blows from the land toward the ocean at night.
- 34. The amount of water vapor in the air.
- 35. A rise in sea level caused by a hurricane’s strong winds pushing water onto land.
- 37. The third layer of the atmosphere, where meteors burn up.
- 39. The process by which gases in the atmosphere trap heat, keeping Earth warm.
- 41. A region near the Equator with little wind and calm weather.
- 42. A scale used to classify hurricanes based on wind speed and damage potential.
- 43. Winds that form in warm regions and influence tropical weather.
- 44. Calm areas around 30° north and south of the Equator where winds are weak.
Down
- 1. Sinking cool air that spreads out at the surface, often causing strong winds.
- 2. Winds that blow from west to east in the middle latitudes.
- 4. Rising warm air that fuels storms and tornado formation.
- 5. A space station in low Earth orbit where astronauts live and work.
- 6. Fast-moving air currents high in the atmosphere that influence weather patterns.
- 8. The transfer of heat by the movement of fluids (liquids or gases).
- 10. A boundary where a cold front catches up to a warm front, causing complex weather.
- 11. A moist air mass that forms over oceans.
- 13. A part of the thermosphere with charged particles that reflect radio waves.

- 20. Steady winds that blow from east to west near the Equator.
- 21. The lowest layer of Earth's atmosphere where weather occurs.
- 22. A boundary where warm and cold air masses meet but do not move, causing prolonged weather conditions.
- 23. The second layer of the atmosphere, containing the ozone layer.
- 24. The transfer of heat through electromagnetic waves, such as sunlight.
