It
is called condensation, when the water vapor condenses in the atmosphere to
form a clouds. This happens when the air cools to the point and mixed with the
dust in the air. Once the cloud is formed, the condensation process still
continues until the air into the clouds
contains water vapor and liquid. Once the clouds get heavy because of the
liquid inside, it will then start to pour that makes it rain. Due to the
unstable atmosphere, sometimes the process of condensation became a strong
thunderstorm.
