Water vapor - Wikipedia
Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is …
Steamy Relationships: How Atmospheric Water Vapor Amplifies …
2022年2月8日 · Water vapor is Earth’s most abundant greenhouse gas. It’s responsible for about half of Earth’s greenhouse effect — the process that occurs when gases in Earth’s atmosphere trap the Sun’s heat.
Why do we blame climate change on carbon dioxide, when water vapor …
2023年11月3日 · Even the exhaust coming from a coal power plant—the classic example of a climate-warming greenhouse gas emission—contains almost as much water vapor as CO 2. 2 It’s why that exhaust forms a visible cloud. But water vapor differs in one crucial way from other greenhouse gases like CO 2, methane, and nitrous oxide.
Water Vapor - NASA Earth Observatory
Water vapor is also the most important greenhouse gas in the atmosphere. Heat radiated from Earth's surface is absorbed by water vapor molecules in the lower atmosphere. The water vapor molecules, in turn, radiate heat in all directions.
Chapter 4: Water Vapor – Atmospheric Processes and Phenomena
Water can exist as a solid, liquid, or gas at typical conditions found on Earth. As we learned, the process of liquid water becoming water vapor is called evaporation and this process absorbs or requires energy. The opposite process is called condensation, where water vapor becomes liquid water, releasing energy.
WATER VAPOR AND THE DYNAMICS OF CLIMATE CHANGES
2010年7月2日 · Water vapor is not only Earth's dominant greenhouse gas. Through the release of latent heat when it condenses, it also plays an active role in dynamic processes that shape the global circulation of...
Condensation and the Water Cycle | U.S. Geological Survey - USGS.gov
2019年9月8日 · Condensation is the process of gaseous water (water vapor) turning into liquid water. Have you ever seen water on the outside of a cold glass on a humid day? That’s condensation.
Is Water Vapor a Greenhouse Gas? - ANAB Blog
2024年11月21日 · Water Vapor Is the Only Greenhouse Gas Whose Concentration Increases . Sincethe atmosphere is warming, water vapor is the only greenhouse gas whose concentration increases and thus climate change causes it to warm even more. Essentially, as the climate warms, water vapor levels will rise in the atmosphere because warmer air can hold more of it.

2021年8月17日 · When water warms and evaporates from the Earth’s surface it becomes gaseous in the form of water vapor, H2O. As water vapor rises into the atmosphere, it cools and can condense into clouds which can produce rain or snow bringing water back to the Earth’s surface. And the cycle begins again.
