5. 1,2 Thunderstorms form in what type of clouds? What atmospheric conditions are needed for this storm to form? Cumulonimbus/warm air rises rapidly

6. 1,3 A scientist who studies the weather is a.. meteorologist

7. 1,4 At what temperature would precipitation change from rain to snow? 0 and 32

8. 2,1 What type of air mass would form over the North Atlantic Ocean? What would its temp. and humidity be like? Maritime Polar/Cool and humid

9. 2,2 Name 3 states that are part of Tornado Alley Kansas, Oklahoma, Texas

10. 2,3 Name 4 types of information that weather satellites collect? Temp, clouds, storms, barometric pressure

11. 2,4 What are the 2 main factors that influence climate? Name two factors that affect Boston Precipitation and temperature, nearness to large body of water, ocean currents

12. 3,1 Name two winds that move air masses in the United States Westerlies /Jet Stream

14. 3,3 Name 3 technological tools used in gathering weather data and improving accuracy of weather forecasts. Balloons, satellites, computers, weather station models

15. 3,4 Name climate region that is most likely in an area located in the interior of a large continent, on the eastside of a major mountain range, with prevailing blowing from west to east Dry or desert

16. 4,1 A major difference between cyclones and anticyclones is.. What type of weather is a cyclone generally associated with? Direction of their winds/ wet, cloudy

17. 4,2 Use the standard two-letter air mass symbols to identify air masses X and Y. Name one safety precaution that should be taken to avoid possible injury from this tornado? X-CP/Y MT

18. 4,3 What is an isobar? Name one unit used to measure air pressure and the instument that does it Equal pressure, mb or inches of mercury/ barometer

19. 4,4 Name a place in the polar region that has a ice cap. Greenland, Antartica

20. 5,1 Name the four types of fronts What type of front(s) would be responsible for several days of rain and clouds? Cold/Warm/StationaryOccluded..stationary

21. 5,2 What is one of the most deadly parts of a hurricane, tornado, and snow storm? Wind

22. 5,3 Why do sea breezes occur in Boston? Explain when and why Daytime land heat up faster than ocean, cool air above ocean replaces the air rising of land

23. 5,4 What causes the monsoons to form? Unequal heating of land and water. Why are they needed in Thailand and/or India?
