Detailed explanation-1: -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: -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-3: -Carbon dioxide is one of the greenhouse gases and an increase in the carbon dioxide content in the atmosphere would cause more heat to be retained by the atmosphere and lead to global warming.
Detailed explanation-4: -Water vapour is water in gaseous instead of liquid form. It can be formed either through a process of evaporation or sublimation. Unlike clouds, fog, or mist which are simply suspended particles of liquid water in the air, water vapour itself cannot be seen because it is in gaseous form.
