Detailed explanation-1: -Steamy Relationships: How Atmospheric Water Vapor Amplifies Earth’s Greenhouse Effect. 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.
Detailed explanation-2: -Water vapour is also an effective greenhouse gas, as it does absorb longwave radiation and radiates it back to the surface, thus contributing to warming. When compared to other greenhouse gases, water vapour stays in the atmosphere for a much shorter period of time.
Detailed explanation-3: -Although water vapor probably accounts for about 60% of the Earth’s greenhouse warming effect, water vapor does not control the Earth’s temperature. Instead, the amount of water vapor is controlled by the temperature.
Detailed explanation-4: -Greenhouse gases include carbon dioxide, methane, nitrous oxides, and water vapor.
