The provided question, "How CloudFormation?", is incomplete. It appears to be asking how clouds form (cloud formation), but could also be a fragmented reference to AWS CloudFormation. Given the available reference text which discusses water vapor and cloud formation, this answer will focus on how clouds form.
Here's a breakdown of the cloud formation process, leveraging the provided reference:
The Cloud Formation Process
Clouds form through a process involving water vapor, air temperature, and air pressure. The key steps are:
-
Evaporation: Water on the Earth's surface (oceans, lakes, rivers, etc.) evaporates, turning into water vapor. This is mentioned implicitly in the title of the reference, "Water Vapor Evaporates Into the Air."
-
Air Cooling & Pressure Drop: As air rises, it cools. As the air cools and/or the air pressure drops, the water vapor can no longer remain in a gaseous state.
-
Condensation: The cooling and/or pressure drop causes the water vapor to condense. According to the reference, "When air cools, some of the water vapor condenses. As air pressure drops, some water vapor condenses too."
-
Cloud Formation: The condensed water vapor forms tiny water droplets. These droplets clump together to form a visible cloud. The reference states: "The vapor becomes small water droplets and a cloud is formed."
In summary: Water evaporates, the air carrying the water vapor cools and/or experiences a drop in air pressure, the water vapor condenses into water droplets, and these droplets form a cloud.
