Answer 1

The most likely cause of clouds forming in a previously clear sky is: A colder air mass moves into the area and rises.

When a colder air mass moves in, it can cause the warmer air that is already present to rise. As the warm air rises, it cools, and if it cools to its dew point, condensation occurs, leading to cloud formation.
