1. Warm air is forced upwards Meets up with cold air Then both cool and condense around dust particles.

2. Classified by shape and size Shape and size vary with … temperature air pressure Amount of water vapor in the atmosphere (humidity)

3. Some clouds are Low and flat Extend high into the sky Some dense clouds bring Rain Snow On sunny days… thin and wispy clouds appear in the sky.

4. The three main cloud types by shape stratus, cumulus, and cirrus

5. form layers of Flat, smooth, even sheets of clouds in the sky. Stratus clouds usually form at low altitudes Stratus Clouds

6. masses of puffy, white clouds Cumulus clouds…Puffy Found at all heights/altitudes

7. Cirrus Clouds Cirrus clouds are curly, almost like hair Very cold and produce snow or ice crystals Form very high in the stratosphere

8. A cloud can have a prefix or suffix that tells more about it like where the cloud is located in the atmosphere… Cirro= high altitude Alto = middle altitude Strato=low altitude Nimbus =bad/ precipitation COMBO-CLOUDS

9. Examples: Prefix Cloud Type Suffix Cirro- cumulus Alto- cumulus Strato- cumulus Cirro- stratus Alto- cirrus Alto- stratus Stratus- nimbus Cumulus- nimbus Alto- cumulus- nimbus Alto- stratus- nimbus = Cirrocumulus = Altocumulus = Stratocumulus = Cirrostratus = Altocirrus = Altostratus = Stratusnimbus = Cumulonimbus = Altocumulonimbus = Altostratusnimbus
