Final answer:
The advancing front may have provided a lifting mechanism for the air leading to clouds and precipitation.
This correct answer is A.
Step-by-step explanation:
The advancing front may have provided a lifting mechanism for the air leading to clouds and precipitation.
The process of condensation and precipitation plays a key role in the formation of clouds and the occurrence of precipitation.
As air rises and cools, it can reach its dew point where water vapor condenses into liquid droplets, forming clouds. If the droplets continue to grow, they fall as precipitation.
This correct answer is A.
