+ Cloud, Cloud classification:
  * Clouds are classified according to how they look and how high the base of the cloud is in the sky. This system was suggested in 1802. There are different sorts of clouds because the air where they form can be still or moving forward or up and down at different speeds. Very thick clouds with large enough water droplets can make rain or snow, and the biggest clouds can make thunder and lightning.
+ Fact, Facts as statements, Examples of fact statements: Philosophy
  * Clouds are usually white.
+ Global dimming, Causes and effects: Climate change :: Environmental issues
  * Clouds stop the heat from both going in and out from the earth. This process is complex and it changes according to the time, location and the height above the sea level. During the day, more sunlight stops from going in. This cools down the Earth. During the night, the heat in earth stops from going out. This slows down the heat from going out the earth.
  * The atmosphere always has a little bit of water vapor that humans can not see. Clouds form when the atmosphere can no longer hold all the invisible air vapor. Any more water vapor condenses into very small water drops. That is what a cloud is.
  * Clouds are heavy. The water in a cloud can have a mass of several million tons. Cloud droplets are also about 1000 times heavier than evaporated water, so they are much heavier than air. When water changes from gas to droplets, this makes heat.
