There is no one layer. The throphsphere is the closest layer to earth, and associated with cold fronts, and thunder storms. The Stratosphere is the second most closest to earth, and is associated with warm fronts (usually a steady rain for a day or so). Then there is the Ionosphere, the most highest clouds which is Ice particles that contain no water vapors that will fall to earth.
the layer (of the earth) that contains the most water vapor is the troposphere
The stratosphere contains almost no water vapor.
Condensation
troposphere
Water vapor and clouds are the stages of the water cycle. The sun (without it water cycle count repeat.) shines on the water causing gas to form above the ground and in the air. This is called water vapor. Water vapor accumulates and forms clouds. Once dense enough from all the water vapor it will then precipate as raindrops.
the layer (of the earth) that contains the most water vapor is the troposphere
It forms clouds.
condensation
The stratosphere contains almost no water vapor.
Troposphere contains nearly all of the atmosphere's clouds. This is for 2 reasons: first, almost all water vapor is contained in this layer. Second, the air is inherently unstable, since it is warmest at the bottom. The causes the air to always want to rise, creating clouds under the right conditions.
Liquid water is changed to water vapor by the process of evaporation (or boiling)Water vapor forms into clouds (liquid droplets) by the process of condensation
Forms clouds
Clouds form when water vapor condenses into liquid water.
Clouds are water vapor, made from Hydrogen and Oxygen -- H2O.
