Question

Why are water vapor and aerosols important constituents of earth's atmosphere?

Answer 1

Water vapor is important because it is the source of all clouds and precipitation and like carbon dioxide, it is also a heat absorber. Aerosols are important bc many acts as surfaces on which water vapor can condense, an important function in the formation of clouds.

Water vapor, steam, or steam is the gas phase of water. The state of water in the hydrosphere. Water vapor is produced by evaporation or boiling of liquid water or sublimation of ice. Water vapor, like most components of the atmosphere, is transparent. Under typical atmospheric conditions, water vapor is continuously produced by evaporation and removed by condensation. It is less dense than most other components of air and causes convection currents that lead to cloud formation.

As part of the Earth's hydrosphere and the water cycle, it is particularly abundant in the Earth's atmosphere, where it acts as a greenhouse gas and warming feedback, and is a more global gas than non-condensable gases such as carbon dioxide and methane. Contribute to the greenhouse effect. The use of water vapor as steam has been important since the Industrial Revolution as a major component of cooking and power generation and transportation systems.
