5. Sunny Days 4 Click the pic The sun’s relationship to earth determines the season. About one million Earth’s could fit inside the sun. Photosynthesi s is a process which uses the sun’s light to grow flowers. It takes 8 minutes for the sun’s light to reach Earth.

6. 5 The clouds in our sky!

7. 6 High Altitude Clouds Cirrus clouds are thin and wispy. Cirrocumulus clouds have a patch like appearance. Cumulonimbus clouds produce lightning, heavy rains, hail, strong winds and tornados. Multi –layer clouds Nimbostratus clouds are very dark associated with large areas of precipitation. Above 18,000 feet

8. 7 Stratus are generally the lowest (besides fog) and don’t have much definition. Cumulus are puffy with distinct edges and have a bit of height Stratocumulus are generally clusters and have a popcorn like appearance. Mid-level clouds Altostratus covers the sky uniformly and it makes it hard to see individual features. Altocumulus are either patchy & scattered or linear bands.

10. 9 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 Rain starts off as ice or snow crystals at cloud level.
