Here's a breakdown of the terms:

* Vaporization: The general term for the process of a liquid turning into a gas.

* Evaporation: A type of vaporization that occurs at the surface of a liquid, and can happen at any temperature below the boiling point.

* Boiling: A type of vaporization that occurs when a liquid reaches its boiling point and the vapor pressure equals the atmospheric pressure.

So, while evaporation is a specific type of vaporization, both terms describe the process of a liquid becoming a gas.
