Clouds - Coggle Diagram

- - - - Puffy, white clouds that tend to have flat bottoms are called cumulus clouds.
      - Cumulus clouds form when warm air rises. These clouds generally indicate fair weather.
      - When these clouds get taller, they produce thunderstorms.
      - Thunderstorms come from a kind of cloud called a cumulonimbus cloud.
      - Clouds that have names that include -nimbus or nimbo- are likely to produce precipitation.
    - - Clouds called stratus clouds are clouds that form in layers.
      - Stratus clouds cover large area of the sky and often block out the Sun.
      - Usually they stretch across the sky in long, horizontal layers. These clouds are caused by a gentle lifting of a large body of air into the atmosphere.
      - Stratus clouds are smooth because they form without strong air movement.
      - Nimbostratus clouds are dark stratus clouds that usually produce light to heavy continuous rain.
      - Fog is a stratus cloud that has formed near the ground.
    - - Cirrus clouds are thin, feathery, white clouds found at high altutudes.
      - The great height of cirrus clouds makes them appear to be hardly moving.
      - Sometimes, they are moved by strong winds at speeds of 100 to 200 miles an hour.
      - Cirrus clouds are made up entirely of ice crystals and are so thin that at night you can sometimes see the stars shining through them.
      - If they get thicker, cirrus clouds indicate that a change in weather is coming.
  - - - is used to describe clouds that form at high altitudes (above 21,000 feet).
      - Because of the cold temperatures at high altitude, high clouds are made up of ice crystals. A cumulus cloud that form high in the atmosphere is called a cirrocumulus cloud.
    - - is used to describe clouds that form at middle altitudes.
      - Middle clouds (7,500 to 21,000 feet) can be made up of both water droplets and ice crystals).
    - - is used to describe clouds that form at low altitude (below 7,500 feet). Low clouds are made up water droplets.
