Across
- 2. Heated air does this
- 4. Balance of incoming & outgoing solar energy
- 9. The amount of water vapour in the atmosphere
- 10. When water vapour turns into a liquid
- 14. Air pressure does this when air is heated
- 17. This type of humidity is expressed as a %
- 18. This occurs unevenly across the Earth's surface
- 19. These are held aloft by the movement of air
- 20. This provides the energy to produce the weather
Down
- 1. These clouds tend to be layered
- 3. Process of watering turning from liquid to gas
- 5. These clouds are fluffy
- 6. These clouds are wispy white
- 7. Without this, Earth would be like the moon Vapour / Water exists in the atmosphere in this form
- 8. May result from large scale cooling of clouds
- 11. Results from a land-sea temperature difference
- 12. These clouds tend to be dark and grey
- 13. Moving masses of air
- 15. This effect results from the rotation of the Earth
- 16. Wind may result from heating and expansion of this
