1. Clouds

2. Cloud Formation Clouds form as warm air rises and cools to its dew point Condensation nuclei (small particles of dust, salt in air) must be present for clouds to form

3. 3 ways clouds form 1. Warm air rising by convection 2. Warm air forced over a mountain (Orographic lifting) 3. When warm and cold air collide in atmosphere

4. Types of Clouds 1. Cirrus- high clouds, thin and whispy, can indicate storm is on the way 2. Cumulus- thick, puffy fair weather clouds 3. Stratus- low dark blanket of clouds, light drizzle Cumulonimbus- large, vertically rising storm clouds

5. Nimbo= rain
