1. Today is Tuesday, December 11, 2012
Homework:
Study for Chapter 7 Test
Warm Up:
Brainstorm with your shoulder partner different types of PRECIPITATION

2. Goal for Today
SWBAT demonstrate an understanding of the different forms of precipitation by describing the formation of rain, freezing rain, sleet, hail and snow.

3. Types of Precipitation

4. Rain
Rain
Ice crystals up high, water droplets down lowerwarmer air below melts it into water

6. Freezing Rain
Ice crystals up highmelt in warmer aircold air close to the ground causes water to freeze when it lands

9. Sleet
Ice crystals up highmelt in thin layer of warm air high above the groundcold air above ground causes rain to freeze before it hits the ground

13. Ice crystals fall from clouds all the way down in cold air
Snow
Ice crystals fall from clouds all the way down in cold air

16. Hail
Strong winds blow upward in a cloud, blowing ice crystals back up into the cloud and making them freeze again. They get blown over and over again, freezing multiple layers of ice onto the outside until they become too heavy and fall to the ground
