Power point on the water cycle and severe weather.

1. The Water Cycleand Severe Weather

2. Water Cycle Water moves from the surface of the earth to the air and then back again. Never ending process

3. Parts of the Water Cycle Evaporation Condensation Precipitation

4. Evaporation Process by which a liquid changes into a gas

5. Condensation Process by which a gas changes into a liquid

6. Precipitation Rain Snow Sleet Hail

7. Rain Liquid precipitation Most common precipitation Temp > 0˚Celsius (32˚Farhenheit)

8. Snow Solid precipitation Ice crystals Water vapor turns to ice

9. Sleet Solid precipitation Frozen rain Ice pellets

10. Hail Solid precipitation Frozen rain Round pieces of ice

11. Severe Storms Thunderstorms Tornadoes Hurricanes

12. Thunderstorm Lightning Strong winds Heavy rains

13. Tornado Fast-spinning spiral of wind Stretches from thunderstorm clouds to ground Winds can be greater than 400 kph (250 mph) 800-1000 tornadoes in U.S. per year

14. Hurricane Large tropical storm Winds speeds of 119 kph (74 mph) or more Form over warm water

15. Weather Safety *Severe storms are dangerous! *Watch TV or listen to radio for directions during severe weather. *Be alert for weather sirens. *Be prepared with a emergency supply kit.
