In vaporization a liquid becomes a gas. This is common in nature and can be seen when water boils on a stove.

In condensation a gas becomes a liquid. This is also common in nature and can be seen when a cold drink is taken outside on a hot humid day and water collects on the surface of the cup. The cold drink condenses the water vapor in the air. 

(Was very confusing to me as a child, I thought the drink was oozing out of the cup. lol)

Condensation is also very important in stellar metamorphosis, as it is very important to a wide range of specific chemicals being present on/inside the Earth. Condensation just doesn't happen with water, its a gas to liquid thermodynamic phase transition.
