Final answer:
When the water-vapor content of air exceeds the saturation point, all of the listed options are possible. Cloud formation, snowfall, rainfall, and a change in global circulation pattern can occur when there is excess water vapor in the air.
Step-by-step explanation:
When the water-vapor content of air exceeds the saturation point, all of the listed options are possible.
Excess water vapor in the air can lead to cloud formation, which can then result in snowfall, rainfall, or a change in global circulation pattern. Cloud formation occurs when the air becomes saturated with water vapor and the water vapor condenses into tiny droplets or ice crystals to form clouds.
These clouds can then release precipitation in the form of rain, snow, or other types of precipitation. In addition, the excess water vapor and cloud formation can also affect global circulation patterns, which can lead to changes in weather patterns and climate.
