7. Uneven heating on the earth’s surface
Weather on earth is caused by….
Uneven heating on the earth’s surface

8. Name the layer of Earth’s atmosphere where weather happens.
Troposphere

9. The ozone layer is found in which layer of Earth’s atmosphere
Stratosphere

10. What happens to air pressure as you increase altitude?
Decreases

11. Ultraviolet (UV) Radiation
The ozone layer protects us from _________.
Ultraviolet (UV) Radiation

12. The sun heats the earth by radiation
The sun heats the earth by radiation. The earth heats the atmosphere by _____________.
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.

13. The source of energy that drives the water cycle is _____.
The sun

14. Clouds are formed by the ___________ of water vapor in the atmosphere.
Condensation

15. When water evaporates from plants.
Transpiration

16. When water returns to earth in the form of rain, snow, sleet, or hail
Precipitation

17. When liquid water absorbs energy and changes to water vapor (gas).
Evaporation

18. This type of cloud is puffy with a flat bottom and usually means fair weather
Cumulus

19. Temperature and Humidity (moisture)
An air mass is a huge body of air with similar ______________ and ___________.
Temperature and Humidity (moisture)

20. Maritime Tropical (mT); warm and moist
Name and describe an air mass that forms over the Gulf of Mexico.
Maritime Tropical (mT); warm and moist

21. Continental Polar (cP); cold and dry
Name and describe an air mass that forms over northern Canada.
Continental Polar (cP); cold and dry

22. The boundary between 2 air masses.
Front

23. What kind of weather always occurs at fronts and why?
Clouds and precipitation because the warmer, more humid air always rises.

24. What direction does wind spin in a low pressure storm such as a hurricane?
Counter-clockwise
