5. The clouds in our sky!

6. High Altitude Clouds Above 18,000 feet Cirrocumulus clouds have a patch like appearance. Cirrus clouds are thin and wispy. Cumulonimbus clouds produce lightning, heavy rains, hail, strong winds and tornados. Nimbostratus clouds are very dark associated with large areas of precipitation. Multi –layer clouds

7. Low Clouds Stratocumulus are generally clusters and have a popcorn like appearance. Cumulus are puffy with distinct edges and have a bit of height Stratus are generally the lowest (besides fog) and don’t have much definition. Mid-level clouds Altocumulus are either patchy & scattered or linear bands. Altostratus covers the sky uniformly and it makes it hard to see individual features.

9. Rain starts off as ice or snow crystals at cloud level. Click the pic Rain drops can fall at speeds of about 22 miles an hour. Rain is recycled water evaporated from our worlds lakes, rivers, oceans, etc. Rain drops do not fall in a tear drop shape, they originally fall in the shape of a flat oval

10. Lightning Florida is the lightning Lightning bolts travel capital of the at speeds of up to 60,000 miles per United States Click the pic second Temperatures in the path of a lightning More than 70% of all people bolt can reach as high as Struck by Lightning still 50,000° F survive

11. Rainbow

12. The order of the spectrum is: RED,ORANGE, YELLOW, GREEN, BLUE, INDIGO & VIOLET. • Everyone sees their own "personal" rainbow due to how we each interpret colors. Newton discovered the seven distinct colors of the visible rainbow.

13. Snow

14. The record snow fall in one season is in Buffalo in 1977 (199.4 inches) The largest snowflake recorded was 15 inches wide and 8 inches thick. There are five different shapes of snowflakes Click the pic

15. Hurricane

16. Hurricane Fast Facts Click the pic Hurricanes are rated from 1-4. A category 4 is the strongest hurricane.
