Answer:
B. cloud formation
Explanation:
The event that will most likely occur is cloud formation. This is because Rising Air is the key process in the production of clouds and precipitation.

Thus, one atom of carbon will combine with two atoms of oxygen to form the molecule CO 2 ( carbon dioxide ). (b) From the chemical formula of the compound aluminium oxide Al 2 O 3 , the valency of aluminium can be determined. ... Hence the valency of aluminium is 3
