9. Key Questions  SWBAT describe the main kinds of storms, and how they form.  SWBAT explain what measures you take to ensure safety in a storm.

10. Storm A violent disturbance in the atmosphere

11. Thunderstorm A small storm with heavy precipitation and frequent thunder and lightning.

12. Lightning A sudden spark as charges jump between parts of a cloud, or cloud and ground.

13. Tornado A rapidly whirling, funnel-shaped cloud that reaches down from a storm cloud to touch Earth’s surface.

14. Hurricane A tropical cyclone that has winds of 119 km/h or higher (about 73 mph)

15. Storm Surge A “dome” of water that sweeps across the coast where the hurricane lands.

16. How Thunderstorms Form Thunderstorms form in large cumulonimbus clouds, also known as thunderheads.

17. Thunderstorm Damage Trees can be uprooted, or areas can be flooded.

18. Thunderstorm Damage Trees can be uprooted, or areas can be flooded.

19. Thunderstorm Safety

20. How Tornadoes Form Different wind speeds will create rotation of the cloud. It will tighten and can reach the ground.

21. Tornado Safety

22. Snowstorms If you are caught in a snowstorm, try to find shelter from the wind.

23. How Hurricanes Form

24. Hurricane Movement

26. Key Questions  What are the main kinds of storms, and how do they form?  Thunderstorms form in large cumulonimbus clouds.

27. Key Questions  What are the main kinds of storms, and how do they form?  Thunderstorms form in large cumulonimbus clouds.  Tornadoes develop in thick cumulonimbus clouds.

28. Key Questions  What are the main kinds of storms, and how do they form?  Thunderstorms form in large cumulonimbus clouds.  Tornadoes develop in thick cumulonimbus clouds.  Most precipitation begins in clouds as snow. If the air is colder than 0 degrees Celsius all the way to the ground, the precipitation falls as snow.
