  1. Clouds Mrs. Wharton’s Science CLass

  2. Clouds • Clouds form when water in the air condenses to form liquid water or ice crystal. • Condensation- The process by which molecules of water vapor in the air become liquid water. • Dew point- the temperature at which condensation begins.

  3. Types of Clouds Classified by altitude and shape • Cirrus • Cumulus • Status

  4. Cirrus • Wispy and feathery • Found at high levels • Made of ice crystals • If the cirrus clouds are isolated, they do not indicate any instability in the weather • If the clouds are dense, they often indicate a storm may be approaching.

  5. Cumulus • Fluffy, rounded piles of cotton • Low level • indicates fair weather

  6. Stratus • Occurs in layers • Low level cloud • Some produce rain or snow • These clouds can produce fog.
