Some weather conditions are shown: • Cold front moves the warm air forcefully and creates an unstable atmosphere • Strong winds • hailstones Which type of severe event is MOST likely to occur during these weather conditions? A. tornado B. flood C. drought D. hurricane
Which best explains the effect a tornado has on normal wind speed and direction? A. A tornado does not affect wind speed or direction. B. A tornado increases wind speed and may change its direction. C. A tornado decreases wind speed and may change its direction. D. A tornado causes wind direction to reverse and may change its speed
Which best describes how changes in air pressure can affect the development of a hurricane? A. Cooling ocean water causes air pressure to drop. This causes high winds and rain to develop, which may become a hurricane. B. Cooling ocean water causes air pressure to rise. This causes light winds and snow to develop, which may become a hurricane. C. Warming ocean water causes air pressure to rise. This causes light winds and sleet to develop, which may become a hurricane. D. Warming ocean water causes air pressure to drop. This causes high winds and thunderstorms to develop, which may become a hurricane.

5. Which is most likely an effect of the Gulf Stream? a.heavy rains in California b.severe drought in Australia c.milder winter temperatures in Florida
In which way are the Gulf Stream and the jet stream similar? a.Both are air current that flow in a certain direction b.Both are ocean currents that flow in a certain direction c.Both bring dry weather to the United States d.Both affect local weather in the United States
