What is the main source of water vapor?
Water vapor can form from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, as are most components 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 is true that water vapor is the largest contributor to the Earth's greenhouse effect. On average, it probably accounts for around 60% of the heating effect. However, water vapor does not control the Earth's temperature, but is instead controlled by the temperature.
Why is water vapor another heat source?
Water vapor is thus another source of heat (besides sunlight) on the earth's surface. These maps show the average amount of water vapor in an atmospheric column in a given month.
What is more important CO2 or water vapor?
Answer: “Forget CO 2. Water vapor is the most important greenhouse gas. It controls the temperature of the earth.”. It is 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 by warm updrafts into the atmosphere. It condenses into clouds, is blown by the wind, and then falls back to Earth as rain or snow. This cycle is an important way in which heat and energy are transferred from the Earth's surface to the atmosphere,…
Which gas is the fourth most abundant in the atmosphere?
On average, the amount of water vapor is 0.25% of the atmosphere, measured 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
