3. The Wacky Weather Phenomenon of HAIL AND SLEET Katherine Cook Mrs. Shott Period 8

4. What is your phenomena Give a definition of what your phenomena is Any graphic that enhances your presentation

5. What is Hail? Hail is a damaging form of precipitation that is similar to a small chunk or ball of solid, hard ice.

6. Is sleet the same as hail? No, sleet is winter precipitation in the form of small pellets of ice. It can make a thin sheet of ice on anything.

7. How does it occur 1 to 2 slides that thoroughly explains how your weather phenomena occurs. Any graphic that enhances your presentation

8. How does hail start? Hail starts as tiny pellets that collide with water droplets that get thrown up and down in the cloud until they are heavy enough to fall. = ice pellets

9. Features of hail Hail has many layers form being thrown up and down in the cloud. Hailstones can be as big as baseballs.

10. How does sleet occur? It starts when snowflakes that melt into raindrops when passing through warmer air. Then they refreeze into ice particles. WARM AIR COLD AIR REFREEZE

11. Where is it? Tell where your phenomena occurs Include a map that shows where your phenomena occurs

12. Where does hail and sleet occur? Hail and sleet occur most everywhere, however some places get more severe storms than others. = severe hail = severe sleet

13. What to do What preparations/precautions do humans need to take to prepare themselves for this phenomena Any graphic that enhances your presentation

14. What can hail do to humans? If hailstones are large enough, they can knock humans unconscious or even kill them.

15. What to do if Hail Occurs Go inside your house or a covered shelter. Avoid going outside unless absolutely necessary. Listen to a local radio or TV station to see when it is safe to come out of cover. Stay off of phones and other appliances during a hail storm.

16. Effects? How does the outcome of your phenomena occurring affect: –Humans –Land –Business Any graphic that enhances your presentation

17. Can hail effect businesses? YES! Hail has been responsible for billions of dollars worth of crop damage and livestock deaths

18. How can hail affect us? Can cause more than $500 million in damage annually. A hailstorm in Prescott Arizona last year destroyed all the cars and trucks at one of the car distributorships

19. Facts Other interesting information about your phenomena. Any graphic that enhances your presentation

20. Wacky facts When hailstones rise and fall, they hit each other, make electric charges, and lightning occurs. Hail falls in the Nandi Hills of Kenya, Africa about 132 days a year!

21. Other Cool Facts The largest hailstone ever fell on Coffeyville, Kansas in 1970. It measured 17.5 inches in circumference and weighed 1.67 pounds.

22. The End Thank you for watching my presentation. I hope you learned something about hail and sleet!!!
