What is the major source of water vapor?
Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.
Is water vapor the most powerful greenhouse gas?
Water vapor is the most important greenhouse gas. It’s true that water vapor is the largest contributor to the Earth’s greenhouse effect. On average, it probably accounts for about 60% of the warming effect. However, water vapor does not control the Earth’s temperature, but is instead controlled by the temperature.
Why is water vapor a second source of warmth?
Thus, water vapor is a second source of warmth (in addition to sunlight) at the Earth’s surface. These maps show the average amount of water vapor in a column of atmosphere in a given month.
Which is more important CO2 or water vapor?
Reply: “Forget the CO 2. Water vapor is the most important greenhouse gas. It controls the Earth’s temperature.”. It’s true that water vapor is the largest contributor to the Earth’s greenhouse effect.
How is water vapor transferred to the atmosphere?
Water Vapor. Water evaporates from the Earth’s surface and rises on warm updrafts into the atmosphere. It condenses into clouds, is blown by the wind, and then falls back to the Earth as rain or snow. This cycle is one important way that heat and energy are transferred from the surface of the Earth to the atmosphere,…
Which is the 4th most abundant gas in the atmosphere?
On average, the amount of water vapor is 0.25% of the atmosphere, by mass (4th most abundant gas). Warm air holds more water than cool air. On a much smaller scale, near the surface forests, the amount of oxygen and carbon dioxide can vary slightly from day to night. Gases in the Upper Atmosphere
