Why does water vapour in the atmosphere affect weather?
Answer and explanation
Correct answer: It is linked with clouds and rainfall
Water vapour is water in gaseous form, and it is always present in varying amounts in the atmosphere. It is important for weather because it can change into tiny liquid droplets or ice crystals when air cools. This process, called condensation, helps form clouds. When droplets or crystals grow large enough, they may fall as rain, snow, or another form of precipitation.
Option B is correct because atmospheric water vapour is directly linked with cloud formation and rainfall. It does not form rocks, dry up the oceans, or stop the movement of Earth. The amount of vapour also affects humidity and the energy involved in atmospheric processes. Thus, water vapour is an essential component of weather and helps explain changing atmospheric conditions.
