Vaporization is the process that turns a liquid into a gas. Vaporization can occur in two ways:
Evaporation is vaporization below the boiling point. Furthermore, evaporation only occurs at the surface of a liquid. That explain why evaporation will not cause bubbles to form.
Conversely, boiling is vaporization throughout a liquid. Because liquid is being turned into vapor at all parts of the liquid, the lower density vapor rises toward the surface. That's why boiling liquids bubble.
As for how vaporization and evaporation are similar, you can say that they both focus on a liquid changing into the vapor state.
The difference between those two terms is bit more difficult. I've illustrated the difference between boiling and evaporation. One difference between vaporization and evaporation could be stated as follows. Evaporation is always a form of vaporization, but vaporization isn't always evaporation. Vaporization could be boiling. It's kind of like saying that all Popes have been Catholic, but not all Catholics have been Popes.
